World's smallest cannon

[Solus]

ice cube and a wrist rocket.  Works gerat for deer too.   No vizable damage to the animal, almost no noise, and no projectiles after a it melts.

hmmm...evil mind at work here.

Wonder if an "ice bullet" could be made and loaded and survive firing in a standard pistol?

A bunch of holes with nothing in them to trace.

I guess any lead bullet mold of the right size would work.

Some gentle loading by hand and then keep them in dry ice till ready to load and fire.

[TAB]

nope, even if it could survie the acceleration, the heat coming from the burning power, the air friction would melt it.

[McGyver]

It was tried by MythBusters, didn't work there either!
