    this is basically a metal tube in which a flammable gas is detonated to make a satisfying BOOM. i have made these before, although not on such a large scale.

     i know that, it's just that if not most, some of us are used to seeing a materials list somewhere around the instructable. Just suggesting you put one up.

     oh, and is something wrong with my comp or is it really there? There's this weird square after the "drill" in no. 5. It says, "5. Drill (square)urn", I'm just wondering what was supposed to be on that square.
