Just make a foil pipe. You use a bic pen to make it. Anyone have a page that shows how you do that? Basically pull the ink tube half way out of the plastic pen tube. Wrap foil around the part where the ink tube and plastic tube connect, make the foil about 7 or 8 layers. Then pull the pen and ink tube out and you are left with a foil pipe with a perfectly shaped bowl. This is much better than smoking from a coke can.

Hope you understand what I'm talking about from that short instruction.
