I need to think of material(s) to use as a stem/bowl to stick in the side of a water bottle(for a homeade bong). I need some answers by afternoon! Thanks.
pens fix the need for stems. and then tin foil, pastry tips, bowl from a metal piece, idk, be creative.
You can cut the straw out of a windex squirter. they're pretty sturdy. Then cut the bottom of a soda can off, and poke some holes in it.
