I know about potato guns and zip guns, but never heard of dry ice bombs till today. That beauty school story was great. I'll bet that one goes over well in the joint *lol*

The old stackable Schlitz cans could be opened at each end and taped together with duct tape. You leave the bottom on the 5th can, and punch a small hole in the bottom. Pour a tablespoon of 90% rubbing alcohol in, and push a tennis ball to the top of the last can.

Flick a bick into the hole, and it sends the tennis ball into the stratosphere. We used to have fights with these "bazookas", and if you took a square hit you went down for more than a minute. I still have a dent in my head from my brother.

Ah childhood... I have other devices we made as kids, using powdered pool chlorine. Alas, these ideas are best left unpublished today.
