Going off thread with this, but given some of the oddball things that have cropped up I would like to know if anyone else knows of beer can bazookas. I did this when in the Navy. You make a tube from empty beer cans (about 5 cans in length) and a lot of duct tape. Using paper you make a cup around the top end which is cut so as to be completely open and punch a touch hole in the base can. Other empty beer cans serve as ammunition, these are placed in the cup you have fitted at the top end, while the propellent is any lightable aerosel spray/lighter fluid sprayed into the touch hole. This was touched off with a match or taper.

Silly, yes. Foolish, yes. not to be done by normal people, yes. Frowned upon now that I am older, yes. Fun at the time, YES.
