The Black Vault

still with 9-11.

Youes will ....... we will' never ever find out the truth either way.

The laws of physics don't care what a bullet is made of as long as it has sufficient energy. Paper shoots hole through rock, you lose, Cole.

Ehh, not too sure about that.

After all they did destroy that beautiful Phantom by crashing it into a concrete barrier at fairly high speeds, can't remember exactly. Several hundred miles an hour anyway.

So it stands to reason, as I see it, that paper won't shoot through rock regardless of it's velocity, you'd need to alter it's density.

Doesn't it gain density the faster it goes?

Density is mass by volume, so I wouldn't think so, but I've been wrong before.

I would think being hit by a paper ball going 2,000 feet per second would hurt a lot more than something playfully lobbed at me.

Tornados have been known to drive a piece of straw thru a 2x4!

You would think it would be impossible to drive a sewing common straight pin thru a penny, because it will just bend, unless you know how to fool the physics involved. So don't say things are impossible too quickly.

That's to do with momentum, which is mass and velocity.


And yes, it would.

I never said anything was impossible, and I was very careful to say that I wasn't 100% sure.

No fooling of physics involved at all. A bullet is less sharp then a needle, it's about momentum and impact area among a whole bunch of other things, it may appear that the physics have been fooled, but only you're perception and understanding of the underlying physics is fool-able.

AH Indeed. Momentum x mass surely my buddy vulcan6gun can explain this by , say, caliber and feet per second. 9 mils pass right thru where as .40 and .45 knock you on your back side. A weak analogy but never the less accurate.

Twisters drive 2x4's thru walls only if the narrow end strikes the wall, long sides damage the wall but fall victim to the mass of the wall. Pretty simple stuff.

A paper spitball would have to be wrapped extremely tight increasing it's mass before it can maintain enough momentum to pass through a rock.

I don't recall any straw through telephone poles at the WTC site.

Cole

I don't recall any straw through telephone poles at the WTC site.

Or the straw that went right in your right ear and out the left!

Try the penny trick tiarra and let me know if you can hammer a pin thru it or did it just bend.
