what happen when you drop a coin off a REALLY tall building?

just wondering about this since i learn harmless water if they go fast enough they can cut through metal and if that the cause what happen if u drop a coin off a high building? heck what happen if u drop off almost outer space then come back down with out getting melted or burn to nothing?

You get a wish if you drop it off a really tall building!

Getting a little excited there aren't you? o.o;

Don't get too excited, and I'm not sure how your water thing goes hand in hand. It rains all the time. Which is higher than a skyscraper. I'm sure if the water was projected at a INCREDIBLE rate, it could do damage to metal.

A penny won't kill anyone either. It was tested on MythBusters

This is what you're probably thinking of.Water Jet Cutter



Otherwise dropping a penny from that high up would be insignificant taking into account wind and all other variables.
If a person was hit by it they would definitely feel it but otherwise I don't think they would suffer any ill effects from the penny.

nothing, coins wont be able to go fast enough from just a drop, if fired thats different
and yeah water is blasted at high pressure, and never think water is harmless its fucking dangerous

damn if a water can cut like that i wonder how far it can go if u just shoot it in the air ... and well that answer my question thought something cool will happen like that part in family guy where peter drop a penny of a tower

well, anything being dropped will reach something called "terminal velocity" the maximum speed anything can travel unaided through the air without any help. a coins terminal velocity is too slow to break through the human skull and kill someone.

it'll hurt like a bitch tho...

Terminal Velocity of your balls dropping OP: 16 years.

IIRC water cutters use the water to carry an abrasive media like sand, so the water itself can't cut the metal/material it's the sand/whatnot doing the cutting.

Beat me to it, good sir.

You should see accidents with high pressure water cleaners.
They can cut through arms and limbs like a hot knife through butter.

Kinsake, the higher you drop doesn't mean the faster it falls. It doesn't keep gaining velocity forever. There's a certain speed that it reaches, and it will keep falling at that speed till it hits the floor.

Like ziggy said, it was tested on Mythbusters and was proved to be false.

Yes, it's terminal velocity

You don't really need the Mythbusters to explain high school physics though...

Your above hypothesis falsified by:
This thread.

I would be hoping for that i would hit someone on there head

You'll just waste money if you drop a coin off a building. Small it may be, but it's still money. The only consolation you'll get is if it hits a bald guy on the head ^_^

true but it heck of a fun to watch XD

You need to drop millions of pennies from thousands of feet in the air so that they melt and become liquid metal rain. That ought to do some damage.
