My friends and I used to make dry ice bombs all the time. 3 Liters worked the best. One guy had a 20 oz. go off in his hand. 20-something stitches. The rest got into some trouble with the Atlanta bomb squad. (I'm glad I wasn't with them that night.) Now we just save it for the 4th of July. Nobody calls the cops for loud bangs that night.

I'll have to try this out.
