Nice one! Another one we used, was a fuse. Blown ones, or ones you'd nick from the fathers shed. lol This was the creme de la creme. Remove cap at each end of fuse. Get role of caps, and fold them up, and then twist them as tight as possible into the fuse. The more you can get in, the better. Stick a match down, leaving half exposed. Light a match, and that ignites your matchstick fuse, and run like f**k!!!! lol
