or you could grab a small piece of a rolling paper, stuff that down the pipe before you pack it, and poke a small hole with a paper clip or w/e.

that's what works for me
slpntrx5 Reviewed by slpntrx5 on . New pipe I got this new metal pipe from EDIT, but the hole in the bottom of bowl is pretty big. I haven't smoked with it yet (saving for 4/20) but it looks like the weed will fall through. Any ideas what I can do? I can't find anything around the house to use as a screen. Rating: 5
