Frequently Asked Questions
How do you do light an outdoor film?
I am shooting part of a short film in a narrow alleyway at night, and I am having trouble figuring out ways to light it. There isn't enough room for a car, and there aren't any outlets nearby. Are there types of portable lamps of something that would work? Or perhaps a cheap generator of sorts? Thanks!
There are TONS of various types of battery powered video lights, but I don't know of any that are low cost, in fact, they typically cost in the thousands. Generators are also not cheap, as well as being heavy and NOISY.
Here is an idea. Buy up several large LED flashlights and get some friends to shine them into the scene. I have seen these lights for under and, while their quality is nothing great, they do put out some intense light. Get several of them and they will probably take care of your problem unless you are trying to literally illuminate the entire alley.
What do you do to get creative ideas?
I'm trying to get ideas for a short film and I'm having trouble with it. So I was wondering if any of you do things to "get the creative juices flowing"? Like do you draw, paint, what do you do? Any suggestion is good. Thanks (:
Sometimes I just focus on a single object and think about it as much as I can. I make it, in my mind, a hero to mankind. Every object is a wonder of God. Did you know that every single bit of matter, even a piece of cow dung, has enough nuclear energy to power a city for a year? Sounds silly, but it is true. We us uranium to power our nuclear generators because it is more efficient than cow dung, but it is true. I could dwell on this for hours, but there are other questions to answer.
What is the name of the siren the VIP govement cars use?
Hello i would like to know what is the name of that siren or if anyone has an mp3 of i would like to use it in a short film |/////
You ask about a siren sound you have heard, but do
not identify it well. Sirens used by all agencies of
government (federal, state, local, private emergency)
are made by many different companies. Of the many,
the U. S. Government, and most states use sirens
made by one of the most recognized name companies
such as Federal Sign & Signal, or Whelen.
Most all of the siren manufacturers can, and will
have several types of siren sounds that are selected
by the user. Common over the years has been the
'wail'. Others such as the 'Hi-Lo', 'French Police Horn',
'warble', and various types of air horn sounds are in
use today, and usually in all quality sirens. That is,
all of the modern electronic sirens.
The loudest type of siren for a vehicle that is always
heard the best from any angle is the mechanical
pneumatic siren. The loudest, largest of these for
a vehicle is the Federal Q model, which can be
found yet on many fire trucks. This mechanical
siren, while being more easily heard in all directions
has taken a back seat to the electronic only due to
the huge drain on a vehicle electrical system,
which requires the use of much heavier wiring,
battery, and generator. These types of sirens can
use anywhere from 50 to 200 amps just to get
them running. They use a motor to turn the rotor.
The Federal Q uses a motor about like a starter
motor, and the amps used is the same as any
car, or truck starter.
When you are seeking a particular siren sound
you also must take into consideration the
particular manufacturer of the siren used. I have
used sirens from many companies, and even
the 'wail' from one to another can sound much
different. In one vehicle I had a particular Motorola
radio system that also had an electronic siren
also mounted in the trunk with all those controls
right with the radio control head controls. It was
very convenient, took up less space than most
others in the front, but sounded way different.
It was so different a sound in all the variations
of siren sounds that it attracted much more
attention than the sounds of all the most common
manufacturers of sirens. (Wish I still had that one.)
To get an idea of the different sounds you can
go to the following websites to play them. You
will be able to hear the different sounds from
different manufacturers. Then you might be able
to pick out which you heard that you are seeking.
How much water is needed to power a water wheel powering a old fashioned film camera?
I'm doing a project where I want to design a water powered cinema using a water wheel that connects to an old fashioned film camera. However, I have no idea how much water I would need to generate enough electricity to power the film camera. Any help that could be offered would be much appreciated
You need to get the power required in watts. This is volts x amps. I don't know whether you mean a movie camera or a movie projector. Obviously a projector, and maybe a camera, need lights. If these are electrically operated, the specification will be there on the name plate, or maybe in a manual (try the internet). If the power is in VA or KVA, just call that watts, as this relates well to an inverter with a battery. If it is large, it may need three phase power. You need to determine the power supply that is required, the power and the voltage and the frequency. This is complicated by the projector lamp, as it may draw a surge much more than the continuous power, maybe ten times more, but only for a second or less when switched on. A battery and inverter or a generator needs to be able to accommodate this surge. The frequency could be critical, as it affects the projector speed. A battery and true sine wave inverter combination is one way to get that. This might be called an uninterruptable power supply (UPS). They exist in quite large sizes (10kW or more). Note this is not the basic UPS used with a personal computer. However a typical UPS is only intended for brief operation, so it may need a bigger battery and to be down-rated for running your system. You would need to consult with someone on this. It may be possible to split the power supply up into various requirements.
This battery will handle surges in power as might be required, and may allow the battery to deliver more power than the water wheel produces, so long as it is only required some of the time. The inverter provides a precise and stable frequency, something the water wheel will not do well..
Once the power requirement (load) is determined, the power from the water wheel can be determined, after allowing for losses in the generator and other parts. The water wheel power is also measured in watts. It will drive a generator, perhaps through a gearbox. The generator may then charge the battery using a battery charger. How this is done depends on other parts of the system.
Without knowing more details, it is difficult to say what you need, as the whole system depends on the power level, and it seems likely some equipment will be adapted to the task. How big is the UPS, how big is the battery, how will it be operated, what generator is used, and so on.
The power available in the water itself comes from the flow and the head. It is calculated as:
Power_W = (volume_liters x Gravity_m/s/s x Height_m) / time_s
volume is the amount of water passing the wheel, during the time in seconds.
gravity is 9.8m/s/s
height is the head (fall) of the water).
This power required is more than the electrical power, as there are losses in the gears, generator, charger and battery. If a battery is used, the water power can be less than the electrical power, as the battery can be charged over many hours and the cinema used for a much shorter time. Though a battery wastes about 40% of the energy it is charged with, it can be used to give a higher power level. It delivers less energy overall, but can deliver more power (for a shorter time). Energy is power x time.
The link below gives some idea of the design of basic types of water wheels, so you can work out what power your water supply can provide, and see how that matches with what is needed. Then you can ask more questions, unless you can see you need more water than you have.
It is probably cheaper and easier to use a large screen TV with DVD approach. The power will be less too. More in the category of a few large car batteries and a true sine wave inverter.
What would it take to determine if a particular business model will succeed in a particular location?
I had an idea for an 'energy store', where people can buy solar cells, solar heaters, wind generators, fans, and towers, etc.
I think you have a good idea there. I am also interested in solar energy. I just saw a film called "A Crude Awakening: The Oil Crash" and agree that oil will soon run out. My interest in energy is purely investment oriented. energy stocks make up the greatest portion of my portfolio. And year-over-year, the energy stocks have outperformed all of my other holdings (including real estate stocks and physical real estate).
In my profession, I get to analyze real estate investments and figure out how the investment will perform in short-term and long-term durations.
My answer to your question is this, analyze all factors leading to the purchase of solar products. You will want to find information about the following:
physical boundaries of your particular location
size of location
busiest retail locations in your particular location
where are the hardware stores?
can you open close to a home depot or Lowe's?
will they end up carrying the same products you want to carry?
where can the current population go to purchase solar products?
how is your pricing compared to online stores
what's your marketing and advertising plan?
do you think just having a store open is enough?
can you use the press to get publicity?
can you work 12 hours a day, 7 days a week?
These are variable I try to figure out when I analyze an investment. I also do a sensitivity test by guesstimating the expenses and then increasing all expense items to see what the worst case scenario would be.
Hope that helps.
I have to film a movie of type film noir. It is due in 2 days, and i can only use myself as a subject. Help :)?
I don't know what to film, please give me ideas. I am the only one allowed in the film.
I have no access to any greenscreen or such.
The end result should be 5 minutes, i would preferably choose to base my film on a horror.
Wow, why such a short time frame?
Just writing the script and shooting it could take at least that long and then you have all the post production like editing, laying in sound, Foley and music.
I guess to get the flavor of the old time cinematic to describe a stylish Hollywood crime drama with emphasize cynical attitudes and sexual motivations, I would shoot a lot of night shots with fog machines running like crazy and convert the whole video to black and white in the final cut.
Sheesh. This sounds more like TV news feature stuff on a short deadline
By you playing all the parts, you may have to shoot the other "actor(s)", you, against chroma key and insert yourself into the "live" scenes in post How good are you at using different voices?
This could be a fun project, but I would think 2 weeks rather than two days. Yikes!
NOTE: You did not tell us what the final cut runtime is supposed to be? Ten minutes? Less?
You could do a dramatic version of Stan Freebergs "hole in the fence" Bang Gunleigh, US Marshall Field
Night shot, close up of hole in fence and one leg wearing slacks and wingtip shoes and the other leg in some high heel shoes all with dramatic lighting and a fog generator adding to the drama. A hand and lower arm with dangley jewelry and a mans with long sleeved French cuff to reach down that touch the hole in the fence. The dialog could be just as simple as Stan Freebergs in that classic radio show.
Need ideas for my year 12 film class script.?
Its supposed to be a comedy, focusing on how teenagers speak to each other. I dont want it to be cliche, like about drugs and sex (but not as if these things dont exist). I want it to be witty and interesting. Have some ideas but not enough for a five minute short film.
Use power-point or a graphic generator (titles) to make it look like a video teaching aid for substitute teachers (pit out by your local school board). The 'host' explains that the hardest part of teaching kids these days is trying to interpret them. He/she then brings in a few kids (or cuts to them in a hallway). Their conversation uses a lot of slang terms like emo,random, uber,wicked, sick,ill, Snookie, etc.....and the educated host completely misinterprets what the kids are talking about.
Even funnier if you make it look like a Seventies film complete with scratchy film and bad sound.
What are some random plot Ideas?
Im trying to write a story and make it to a short film.
Can you give me an idea or give me a sentence to start the story or work around to create in the story..
Plot generators are helpful because they throw ideas together that many people wouldn't think of. This is one of my favourites (just press F5 to get another plot): http://www.archetypewriting.com/muse/generators/plot.htm
Ran out of idea! Please help :)?
I need to be able to think of short video an short film ideas.... Does anyone know any good ways to get inspired with ideas?
Try googleing "Idea Generator" they're of various qualities but should at least get you thinking of a few topics you wouldnt on your own! good luck!
what kind of lights do i need?
my friends and i are making a short film for the hunger games, and we know all of the equiptment we need, we just need help with lighting. Obviously, the majority of the movie is outside. we'll be filming pretty far out in the woods, so i need a light that doesn't need a plug, unless we can find one that had a fifty food cord. what kind of lights do we need? thanks
A rule of thumb is three point lighting. That'll be your main light, fill light & back light. Three hundred watts for each light is a good a start. Are you going to use tungsten or led lights? 3200K or 5600K temperature lights. You can also adjust the light intensity with diffusion paper or scrims. You will also need gels, CTB or CTO or different color gels for different moods. Also you will need to power the lights with a generator, if you don't mind some noise. 1500 watts minimum for the generator. Have fun in the production. There are a lot more other things but you'll have others that'll have more ideas.
Ideas for teen books?
I love to write and I've been running out of ideas to write about. What would you want to read about? It can be about anything. Also include some ideas for characters. Please ! (:
Copy and pasted from the same exact question that you posted a few hours ago:
Oh, here we go.
I'm guilty, I've asked this question before.
When I was 12, and I had no idea what it meant to be an artist or a novelist.
Well, let me enlighten you in case you are unaware of the definition.
A person who produces paintings or drawings as a profession or hobby.
A person who practices any of the various creative arts, such as a sculptor, novelist, poet, or filmmaker.
A person who has written a particular text.
A person who writes books, stories, or articles as a job or regular occupation
No where in there does it say that they steal ideas from others, right?
It's part of your job as a writer to come up with your own ideas. It's okay to find inspiration- in fact, that's where ALL stories stem from. You can find your ideas by listening to conversations in restaurants or at school, by parts of another story or film, by pictures, anything! But it's your job to come up with it.
Trust me, if I had a decent enough idea that deserved to be written, I'd be writing it. I wouldn't be handing it out to a stranger on the internet.
There are things like the plot generator on seventhsanctum.com that comes up with totally wacky and weird ideas, if that would help you. Sometimes, I like to come up with my characters FIRST and then come up for a story to place them in. Sometimes, vice versa. Whichever way gets the job done, really.
If you don't have an idea now, just write the first thing that comes to mind. Anything. Don't stop and go for five minutes. This is called a free write. If you feel up to it, keep going. If you want, find five or six words and require yourself to fit them in somewhere. Come up with a silly story and write it out. Do research on historical events and come up with something that way. Randomly google search a name, find a photo, read other stories.
In short, you're not gettin' anything from me. That's. Your. Job.

LED Video Lighting *urgent*?
Hi I've recently been looking for some new more portable and versitile video lights to replace my cheap can light set from Home Depot. I shoot all sorts of things, infomercials, interviews, documentaries, but my real passion is in short films. The problem is I don't have a very large budget to buy different light kits for each job such as softbox fluorescents or anything like that for interviews because I then can't use them when I'm moving from place to place when shoring a short film, most of which i dont have access to power. The bottom line is, I'm looking for an affordable, reliable, and pretty durable LED light kit. I only need 3, as I already have 1 small but suprisingly bright one. They don't need to be anything fancy but something that will get the job done. My price range would be around 0 or less. And yes I've checked and B&H Photo but unfortunately most of it is too out of my price range, I've also hit a dead end at eBay. Amazon is probably the best option I just have no idea what to get.
Summary (sort of):
Need at least 3 LED light panels for video. Preferably AC and DC power able but if needed I can buy a small generator for power
Size: Decent regular size (not the small DSLR hot shoe mount ones)
Wattage: 1000 preferably
Price: under 0 for all 3 maybe can push for 600 but reasonable please
Do not need stands as I have some already
Looking for alternatives... Try guitarcenter.com or musiciansfriend.com. In the DJ lighting area.
AC only... but relatively low power so an inverter and a deep cycle battery or two or a generator should have no problem with them.
http://www.guitarcenter.com/American-DJ-LED-Display-Bar-H70512-i1735297.gc (might not be bright enough)
There are others - most (not all) can go just white, otherwise if all RGB, then that works - and you could put a diffuser in front of them if needed. You can add the DMX controls later if you want dimming. Selecting a single color is easy to do using the DIP switches on the back.
Any GOOD SCIENCE FAIR PROJECT IDEAS?!?!?!?!?!?
I know this type of question doesn't get many answers, but anyone who crosses this and reads this, PLEASE suggest something, and make sure it isn't a dumb one... it has to be one that almost 90% of people wouldn't know what would happen. In other words, no volcanoes and junk with baking soda... or in other words, just don't, and i repeat DON'T, put plain old classics...

Pick one of these short story themes for me?
I'm entering a short story competition, in which we have to use a random story theme generator as a basis for our stories. I have a few themes that i like the look of and i think i could write from, but i just can't choose! They're listed below with a few of my initial ideas. Help me choose?
Your story is about a mortician in a waiting room telling bad jokes:
Covering for an absent receptionist.
Usually an embalmer because of poor people skills.
The dead usually 'laugh' at his jokes. (delusional?)
Telling jokes to a waiting, grieving family.
Dead baby jokes?
Your story is about a house wife in a mental institution fixing a hole puncher:
Desperate housewife/stepford wives type character?
Irony- housewife fixing office equipment
Your story is about a dentist behind closed doors having a baby.
At an abortion clinic?
Leaves the baby behind.
Stuck in a lift?
Your story is about a risk assessor in a car turning into a penguin.
Michael Douglas in 'Falling Down' type character. The film's opening scene- hot, stuffy, irritated in a car.
Assessing the situation.
i tend towards dark humor so go with the funeral home story.
I want to build a transformer for school project ...Suggestions ?
Okay so Here's what I've decided to do ..
(After rejecting several topics like tesla coil, van de graff generator, electroscope,galvanometer, DC-AC converter...I've arrived at this..)
I got 4 days to build it ...
So Im going to take some magnet wire ...say 240 turns..
thats the secondary ...Stuff the cardboard roll (like the one that comes with aluminium foil)with iron nails (to get a partial iron core)...wind the secondary on top of it..
Then wind the primary say 20 turns...
(now the ratio is 12 ...considering pathetic efficiency lets assume it to be 10)
So now I got a potential difference of say 50 volts in the primary ..
what I'll get a in secandory is 500 volt..
I can stick in a multimeter..to confirm the voltages...stick in a diode in the secondary ..and charge a capacitor ( layden jar, also homemade)...then discharge it to observe a awesome lethal spark...
[to the smart people : I know the dangers of high voltage, I will handle it carefully]
Pls understand , I have to create the entire thing myself,and demonstrate it with it's uses..
and also make a report file on it ..
Any suggestions ? pls tell
Any problems with my plan that you spotted ? pls share.
Your ideas are valid. An ignition coil in a car is quite closely related to this.
This is what is called an induction coil. The main issue is what supply to use. Do not even consider connecting it to the mains or a transformer. Another issue is the number of turns to use. I think your primary is about right for a 6 to 12V battery. If you use a car battery it will be easy to burn out the primary wires. Best to use 4 x alkaline D cells or a lantern battery as these will limit the current slightly, make it less likely to accidentally burn out.
For high voltage, the number of secondary turns is usually much higher than you have, and it is the rapid collapse of the magnetic field when the contacts open that gives a high voltage, because that generates a high voltage in the primary to start with. However you can expect peaks of 1 or 2 thousand volts if all is well. This will jump a shorter distance maybe 1 or 2 mm. Try reversing the primary connection which may increase the voltage. Do not connect to a multimeter, it will be damaged. Just use sparks to show voltage, maybe 2000V/mm.
As you say the efficiency of this will not be high. Ideally the nails will be thin, and insulated from each other by varnish. The core only needs to be around 1cm diameter. If you arrange the nails in the core so they are all presenting a flat face at one end, they can act as a magnetic pole that can attract an armature made of ferromagnetic material from maybe 1 or 2 mm away.. This armature is held by a spring, so when a battery is connected the armature moves to the pole, and when disconnected, it releases and springs back. The armature is fitted with a contact so the whole thing can be automated. The operation is the same as an electric bell or buzzer.
The capacitor across the contacts improves operation. It could be a leyden jar, but generally the capacitance will be less than you need. You can also make this capacitor from 2 strips of foil say 32mm wide, with a sheet of cling wrap film between, then rolled up into a compact cylinder. The connections to the two sheets of foil are the problem. You are short of time, leave it out, till later. Buy a 0.033uF (33nF) capacitor rated around 600V later to see the result.
Winding the wires:
The layers should be neat and solenoid like, not just scramble wound. There should be insulation tape every few layers. The wire insulation is limited in withstanding voltage. The primary is the inside layer. There should also be a layer of tape between the primary and the secondary. The primary is thick wire, say 1mm diameter, and the secondary can be very thin, in fact like human hair is usual. This is called magnet wire. The modern type is much easier to use than the stuff with silk or cotton insulation used 100 years ago.
The pulse at the secondary is expected to be mainly in one direction (asymmetrical), so no rectifier is needed. The leyden jar will charge to the average voltage. The Leyden jar ends up as if charged from a battery. The second link below shows some experiments based on this, but those charge related experiments will not work well unless the humidity of the air is very low.
The last link shows the voltage across the inductor, however this is asymmetrical because the collapse is faster than the build up generally.
Jurassic Park Reconstruction The Real Deal 2012?
Jurassic Park Reconstruction The Real Deal 2012
Real Jurassic Park? But how? Where? It has been a story for a some time now, Austrailian Billionair "Clive Palmer " is discussing plans to use real DNA working with the same scientist who cologned Dolly the sheep, to create his own Jurassic Park based on the film in 1993.
Palmar plans on building a 5 Star hotel on the deserted island "Flores" in the North Atlantic Ocean, as seen in the movie reinforced high voltage Fence, and cages are expected to be built, along with a Power plant and controled habitat. Along with gift shops the hotel is expected to acomidate, over 1200 rooms 2 restraunts 3 indoor pools and put put golf.
The plan starting in September, 2012 is expected to cost over Billion the begining of the research and construction of reinforced habitats, as of Next year they expect to start the hotel sometime around July 2013.
The project is not expected to be finished untill 2016 also expected ways of travel are by cruise, or fastest by plane.
Good Idea? or Bad Idea? Palmar says if everything goes well, the Fences will all be ran on Back up power 24/7 and anything dangerous will be inforced by fence made from 12" Steel pipe 24' High and each pipe will be within 8" Apart. For The T- Rex also they expect to control that Male and Female Dianasours are seperated, and only a controle number of animals will be on the island at a time.
I think its a good idea, yea we've all seen the movie, and they let 1 guy screw them over by shutting the power off, Let's just not let that happen this time Palmar says the power will be gaurded and well engineered, any chance of power outage 2 Automatic Backup generators are there to automatically take it's place. Also expected to keep daily maintnance and security checks.
Considering that cloned animals today have about a 1/100 chance of surviving past birth, cloning technology is still in it's infancy. Even if cloning dinosaurs becomes possible, it's not going to happen in probably many decades, possibly even centuries, much less four years. That is an entirely unrealistic timeframe. So in short, this isn't going to happen.
How do you think up plots?
I love short story writing. I have characters and situations I can write about, I can never think of a credible start, middle and end. It's like I have a huge case of writers block but JUST about thinking of plots. I can easily create characters, situation, dialogue, etc... but I am always stuck when it comes to crafting a structured story.
Can anyone help? Please don't suggest those "plot generator" websites. They are no help to me. They give you a theme, a name, and a few other things, but I need a way to actually think up a structured plot. What happens at the start, how do you get to the middle and how does it all end?
Has anyone else had problems with this?
Don't worry. You have the skill, you just start backwards. Since you already have your characters developed and sequence of events, you pretty much 'currently' have somewhat of a plot. I suggest taking a break and listening to some music. Run your story or events through your head like a movie and narrate them (so you have a way of putting what you see into words) and soon your mind will just take off. You'll have millions of ideas in just minutes.
Think of those awesome film previews you see on TV. If it's a horror movie, it seems tense and suspenseful bringing in your undivided attention. Then your eager to go see the movie. Try running your thoughts in that manner. Making you eager to keep going. You'll then know the exact plot/idea of the story.
Hope I helped
How can I assemble a working mechanical powered projector?
I wasn't sure how else to phrase the question above. I'm currently working on a sculpture project that takes found objects TV casings , Bicycles, lights, etc, and combines them together to make a larger complex machine. At the moment the plan is to have a large tv case that you sit behind , using the bike pedals you turn the film reels on the inside of the case. I already know how to provide the musical soundtrack with a music box, the thing is I know that film needs to be projected at a constant speed, 22 fps I believe, I was wondering if anyone knew how or of someone who would know how to set this up so that the film wouldn't tear before the correct speed is achieved or if this idea is even possible.
The film is not going to tear from to low, or to high a speed if it is no being stretched in the process. The tensile strength of the film has it's limits, this is true. That said, the reels should be supplying the motion for the film, with no stretching of the film as the reels move to unwind it, and then rewind it. About the best thing to do, short of figuring out how to make a mechanical system to fit your needs would be to find an old Bell and Howell projector, put a small generator on your contraption, and use the projector to move the film. Short of that, you need a supply reel, which you say that you have as well as the take up reel, that move together at the same speed, as well as a toothed gear to fit into the small holes on the side of the film to move the film at a constant speed through the lens assembly. The reels can't turn to fast, or to slow such as to cause drag, or tension on the film as it enters and leaves the lens assembly. See if you can find a projector as I have named, or a similar one and study how it works. This might help you with your project. Schools, and colleges would be a good place to look for such projectors, as well as on Ebay.
What are her views on 911
On the same airdate as her remarks about the captured British troops, O'Donnell said that 7 World Trade Center had been imploded, in line with 9/11 conspiracy theories. "It is impossible for a building to fall the way it fell without explosives being involved," When asked by a co-presenter who she thought was responsible, she commented that she had no idea, but argued in a blog entry that the building was blown up to destroy evidence of the corporate financial scandals at Enron and WorldCom. O'Donnell said:
“ I do believe that it's the first time in history that fire has ever melted steel. I do believe that it defies physics that World Trade Center tower 7 — building 7, which collapsed in on itself — it is impossible for a building to fall the way it fell without explosives being involved. World Trade Center 7. World Trade Center 1 and 2 got hit by planes — 7, miraculously, the first time in history, steel was melted by fire. It is physically impossible. To say that we don’t know that it imploded, that it was an implosion and a demolition, is beyond ignorant. Look at the films, get a physics expert here [on the show] from Yale, from Harvard, pick the school — [the collapse] defies reason. ”
Her comments were cheered by some of the studio audience. Talk show host Bill O'Reilly implied that "ABC should do something", but stopped short of calling for her firing. O'Donnell responded to O'Reilly's criticism on her blog, claiming that "...he edited my statements to make it seem as he wanted".
On April 2 and 3, 2007 former Congressman Joe Scarborough, on his MSNBC show Scarborough Country explicitly called for ABC to fire O'Donnell.
On March 30, 2007, Popular Mechanics magazine posted a point-by-point response to O'Donnell's claims on its website, which included a scientific correction to O'Donnell's statement about steel and fire: Tower 7 housed the city's emergency command center, so there were a number of fuel tanks located throughout the building—including two 6000-gallon tanks in the basement that fed some generators in the building by pressurized lines. The working hypothesis is that this pressurized line was supplying fuel to the fire for a long period of time. Steel melts at about 2,750 degrees Fahrenheit—but it loses strength at temperatures as low as 400 F. When temperatures break 1000 degrees Fahrenheit, steel loses nearly 50 percent of its strength. It is unknown what temperatures were reached inside WTC7, but fires in the building raged for seven hours before the collapse. O'Donnell responded to the Popular Mechanics article on her blog, stating, "I still believe explosives were used to bring down wtc7".
Rosie is a moron who has brain farts instead of statements. She needs to get out of the View somewhere else where she will only make a total a** out of herself.
