i made a chillum out of a test tube and i drilled in a carb and stuff. it seems like it will work fine, its basically the same set up as a crack pipe, it has steel wool for a screen. thats where i was wondering, is it safe to use steel wool instead of a screen? the closest head shop is like 45 minutes away from my house. i also just cant get my hands on a spoon like id like. so will this hold me over till i can get a spoon?
