- totorototoro, on 10/11/2007, -9/+181I propose a new unit of measurement, the ROD (Rosie O'Donnell) to measure this new phenomenon.
- Godlesswanderer, on 10/11/2007, -2/+66I don't see why they couldn't have just gotten a big chunk of Gelatin, of course the bullet shock wave is going to shatter the perspex. I don't know about you but I've never seen a fat guy encased in a perspex tube.
- desistere, on 10/11/2007, -2/+49Remember what you have learned today:
The internal organs of inordinately fat individuals would be ruptured by a large helium-powered gun using round ball bearing bullets at supersonic speeds.
The internet allows you to access more information than ever before. Unfortunately, it's mostly trivial or useless except for the porn. - holygram, on 10/11/2007, -2/+38OR....you could be super thin and be more difficult, if not impossible, to shoot.
- ChromaVita, on 10/11/2007, -4/+38Proof it.
- abeg, on 10/11/2007, -2/+35I'm not fat that's my body armor
- SurrealDream, on 10/11/2007, -4/+37I remember in GTA:SA, the more fat CJ had, the more bullets he could withstand before keeling over in a pulped yellow/red mess.
- Meleez, on 10/11/2007, -5/+36If you're fat enough to stop a bullet, you're more likely to die from obesity than the bullet in the first place.
- omnirusa, on 10/11/2007, -2/+32Anyone else hesitate to click on this after reading the title and seeing its from www.thenakedscientist.com
O_o - NihilistZealot, on 10/11/2007, -0/+25If the bullet doesn't kill you, the heart attack will.

"
How fat would you have to be to stop a bullet?
Have you ever wondered how fat you would have to be to stop a bullet? Well we did, and we went to the Cavendish Laboratory to find out. A perspex tube was filled with gelatin, which is a similar density to fat, to act as the target. This was mounted in front of a backstop full of rags. The bullet hits the gelatin at about 500m/s, that is over 1100mph - nearly twice the speed of sound!
We used a gas gun, which is basically a huge air rifle. There is a chamber that is filled with high pressure helium (this is used because it is lighter than air so will expand more quickly). The gun has a 3m long barrel which you load a small ball bearing into. There is a valve between the chamber and the barrel which can be opened very quickly. The gas (at about 70 atmospheres) then expands extremely rapidly forcing the bullet out of the barrel at supersonic speeds.
While the bullet is passing through the jelly it creates a conical shaped hole behind the bullet. This is because to get out of the way of the bullet the jelly has to move very fast, and once the bullet has passed it will keep moving in the same direction expanding into a cone.
Bubbles form in front of the bullet, this would not happen in reality, it is because the perspex tube is stretched where the bullet hits it, and this stretch travels down the perspex as a wave faster than the bullet is moving, so the gelatin is stretched forming cavities.
It all gets too much for the perspex which shatters. The bullet leaves the Gelatin at about 180m/s. This means that by a very rough approximation you would have to have twice this much fat to have stopped a supersonic bullet. That is 72cm of fat and is somewhat unfeasible, We think that bullet proof vests are probably more practical and probably cheaper!
" - lardlung, on 10/11/2007, -1/+16How fat does your server have to be to stop a raging horde of sunday Diggers?
Fatter than theirs... - TheFrod, on 10/11/2007, -0/+15"I don't know about you but I've never seen a fat guy encased in a perspex tube."
I have!! on the internet!!! - Hindu_Wardrobe, on 10/11/2007, -3/+17Mirror?
- daedalus779, on 10/11/2007, -0/+14lets leave the myth busting to the professionals please.
- Moosebern, on 10/11/2007, -2/+16How about how much muscle it would take to stop a bullet? I don't see a really fat guy and say, "Whoa, I bet that ***** could stop a bullet." However, I do see built guys and wonder how much muscle it would take.
NEW EXPERIMENT. - shiznit, on 10/11/2007, -5/+18Lame. For starters use a real gun and real bullets for this experiment or change the title to: "How fat would you have to be to stop a ball bearing from a hacked together helium canon". Second, while 500mps might be impressive to these lab rats, it's not in the world of ballistics. A .30-06 with 168 grain round achieves around 822 mps.
- arcooke, on 10/11/2007, -0/+13If nothing else, she'd make a really fun human shield.
- quomen, on 10/11/2007, -3/+15Lets just say that you have to be PRETTY ***** FAT.
I actually had a roomate that would probably bounce bullets off his goodies. - cimordnilap, on 10/11/2007, -0/+9I read about this also in the book "Does Anything Eat Wasps?" they hypothesized that a dude would need to be 1600 pounds inorder to be bulletproof, although one bullet in the right place could still kill this man. Cant tell if thenakedscientists got the same conclusion since the sites down.
also leads to "yo momma so fat .... she could stop bullets." - luweez90, on 10/11/2007, -1/+10Why does almost every article that appears on here now FAIL so fast? O_o
- strictlybogart, on 10/11/2007, -0/+8clearly it only has FAT16...
- graystar, on 10/11/2007, -3/+10How about CJ from baywatch? A bit of silicon might help out.
- christoast, on 09/04/2008, -0/+7/r/ mirror
- SurrealDream, on 10/11/2007, -0/+7No no, we all know silicon deflects laser beams.
- strictlybogart, on 10/11/2007, -0/+7you! again! stfu with the tarot card spam.
- Linkage155, on 10/11/2007, -0/+6My Pamela?!
- numeka, on 10/11/2007, -6/+12Just goes to show.. no matter how fat you are, you're still human.
- inactive, on 10/11/2007, -0/+5They should have tested this on better subjects, such as American Idol contestants, pop stars, rappers, or whoever got us into the Iraq war. No wait - is that guy Carrot Top still around? Okay then, Dane Cook.
- Azdak, on 10/11/2007, -1/+6"With pics" is just Diggspeak for "down"
- thunderer, on 10/11/2007, -0/+5Having to scroll down this far to find a mirror? I like the old first comment abuse system better.
Yarrrr digg, listen! - GravitySpec, on 10/11/2007, -0/+4It would be a good experiment. Muscle is much more dense than fat, which should be able to apply more resistance than fat. If anything, this would show an added need to lose weight.
- arcooke, on 10/11/2007, -1/+5That's a big negative
- Hickeroar, on 10/11/2007, -2/+6Well, on top of that, the bullet used, a ball bearing, is high unrealistic (defensive bullets are designed expand and slow down very quickly to remain inside the target's body (plus maximize effectiveness)), and most common bullets fly out of tiny barrels (not 3m) and are just barely at supersonic speeds or far less than supersonic. A .45 cal bullet runs 700-800fps on average. The speed of sound is about 1100fps.
Also, ballistic gelatin doesn't mimic real tissue very well at all, and firing it into an enclosed tube containing gelatin is just stupidity. Tissue stretches a LOT. Gelatin barely stretches at all and the plastic tube stretches NONE. Conversions of distance also often have to be done to see how far a bullet "would have" gone in human tissue as compared to the gelatin performance.
The person running this test needs to re-examine their methodology. - hmunkey, on 10/11/2007, -1/+5Lol... ^^^
Bullet "prove". So, you're pretty much fat and stupid. - Kbiscu1t, on 10/11/2007, -3/+7That's incredible!! Man, I wish I could carry out those experiments....that is, with Gelatin....
- smackywentz, on 10/11/2007, -0/+3...and this didn't even answer the question in the first place. Title should be changed to: "Watch a ball bearing go through some gel."
- kendawg, on 10/11/2007, -0/+3So the answer is 650kg, or about 1450 pounds. That website actually answers the question, rather than showing some video that means nothing.
- heynow21, on 10/11/2007, -4/+7God damnit I've been gorging on food for the last 2 years encasing myself in fat because I assumed I would be invunerable to bullets. I was going to market myself to the CIA as a kind of superhero mercenary and battle Al Qaeda. I guess this article is a blessing, but it's crushed my dreams.
- smackywentz, on 10/11/2007, -0/+3Wow, figure all that out by yourself? You should be a detective.
- jmp478, on 10/11/2007, -0/+3How very mature...
- zeiben, on 10/11/2007, -0/+3Finally. News I can use.
- rouslan, on 10/11/2007, -0/+2I like how the embedded flash player was custom sized to fit the other images.
- alexgg, on 10/11/2007, -3/+5Better link it to a mirror ;)
http://www.thenakedscientists.com.nyud.net:8080/HTML/content/kitchenscience/exp/how-fat-would-you-have-to-be-to-stop-a-bullet/ - Recuso, on 10/11/2007, -0/+2We already have the Rod. And my car gets forty rods to the hogshead and that's the way I likes it.
- hankyone, on 10/11/2007, -1/+3Welcome to the internet, its called the Digg effect / Slashdot effect
- meatwadlurker, on 10/11/2007, -0/+2Everything about this experiment is flawed.
Flawed shape of bullet, speed of projectile, surface that it is hitting are three that radically affect this experiment.
Buried as inaccurate. - mlw4428, on 10/11/2007, -0/+2tinyurl is never a better link.
- fLUx1337, on 10/11/2007, -0/+2sites down...
But it was on UK TV in a "Mythbusters" kinda show...
Think it would be around 1.5m wide for you to be bullet proof..... - psykiv, on 10/11/2007, -0/+2Buried for Strawberry clock.
