hehe... length of pvc pipe around 2 inches in diameter, duct tape that to an old fruit tin, put a small hole at the top of the fruit tin, just under where the duct tape joins it, put a bit of metho in the bottom, say about a table spoon or two, pour it down the pvc pipe, cut a potata so the segments are about 2 inches wide, jam this on the end of your pvc pipe so the 2 inches is length wise down the pipe. Jam it down to the bottom of the pipe with a peice of broom handle, best to measure this before hand so you don't end up pushing the peice of potato into the can. Then! hold the side of the can NOT near the hole, put a match over the hole..

Looks great at night. Theres a new fuel come into the supermarkets, supposed to 100% hydrocarbons, I want to try it in mine, but don't want to.. due to the fact that it could possibly explode.

Oh, make a few wrappings of duct tape around the join.. I've had instances where the thing has weaked cause of the heat that's generated and the flame has burst out the side rather than pushing the potato out the pipe. You have been warned
