You can make something similar with tennis ball cans - 2 tennis ball cans duct taped end to end (with the bottom cut off one of course) - punch a hole in the side for the butane nozzle, and shove a tennis ball down the thing. Squirt in a little butane, allow a few moments for evaporation and hold the lighter up to the hole. *THOOM!* it'll send a tennis ball skyward at about 100 mph. It's a lot of fun until the tennis ball catches fire. We ended up chasing a flaming tennis ball down the hill because we thought it'd burn someone's house down. Fortunately if you have 2 cans, that's 6 tennis balls!
