toilet paper roll with the paper taken off.
tin foil
something to poke holes with


cut a hole in the middle of the roll about nickel sized. Make a bowl shape from about a 1.5*1.5" square of aluminum foil. Poke tiny holes in the foil and mold the foil to make a nice bowl and mold it to the shape of the roll. You can poke about 5 or 6 holes.


That's a steamroller. Cover one end with your hand, that's your carb. A big ass carb at that too. It'll hit well, and be simple to use like any other pipe.
