Myths Thread

Recommended Posts

Post your myths that you've heard and see if the forum can help enlighten weather there true of false. Or if you know the answer post it up aswell.

This ones from myth busters. Filling a football with helium doesnt make the ball have anymore hang time or go further.

I was told never to swallow chewing gum because it takes years for your stomach to digest. True or false does anyone no the actual answer?

thhnk the actual number they always say is 7, but its in fact bollox, according to someone or other something that small will pass through your digestive system relatively quickly and easily.

If you shot a gun up in the air, would the bullet kill you if it hit you on the way down

Thing about that is, the bullet would go up, likely hit crosswinds, and be blown off course, so when it's gone high enough to lose its speed, it will fall back down, reaching a similar speed, but you would be incredibly unlucky to be hit by it because it would never come back down in the same place.

That said, you might shoot it, wait, think, f**k this its not coming back down, walk off and then it land on your head.

If you masturbate too much you will have a sore dick and no jizz.

:lol:

The bullet one would kill you as much as anything else falling at speed, probably less then a lot more objects.

Denied. Terminal velocity of a falling bullet is different to the velocity of a bullet fired from a gun.

After it stops and turns, no matter how much it's spinning from the gun's rifling, it will tumble, slowing it down. It will never pick up the speed it had as it left the gun's barrel.

As it's so light, it won't have anywhere near enough momentum to do damage enough to kill a person.

Depends on the bullet. If its something like a .50 calbire bullet its got more weight than a penny coin, which can kill you if dropped from the empire state building etc.

That's not true, either. :giggle:

Terminal velocity is just too slow.

A 9mm bullet weighs about 0.03kg, and travels at 900 meters per second. It has a momentum of 27 kg m/s, which is quite a bit.

That's about triple the weight of a penny, which I will say weighs about 0.01kg, meaning it would need to be traveling at 2700m/s to have the same momentum. Which is 6000 miles an hour.

Even if you half that, that's 3000mph.

The Empire State is 381 meters tall, so if the penny is dropped from the top, accelerating at 9.8m/s, when it hits the ground, it will be traveling about 84 meters per second (190mph).

Which leaves it about 16 times too slow to do half the damage of a bullet, before we even look at wind resistance...

What about if the person it hit was looking up at the time and it went in their eye, or it got lodged in their windpipe because they had their mouth open :P

"and a typical 150 g bullet travelling in the downward vertical direction which is returning to earth having been fired upwards or perhaps just dropped from a tower, which has a terminal velocity of about 300 feet per second (90 m/s) according to a 1920 U.S. Army Ordnance study[3]."

Found that on Wiki.

So it appears the Terminal Velocity for the bullet is more than anything else =/
