all this costs is a $10 down stem from your local head shop. It can also be used to make a gravity bong but I find them to be a bit nasty.
i'm not smoking the bottle, I'm merely using it to make a bong. I wouldn't smoke aluminum, I tried smoking from a can before that was absolutely terrible made my throat so fucking sick and fucked. Not worth it. The plastic in this scenario doesn't bother me. Easily made. Easily trashed and replaced. Any and all of my gravity bongs have been plastic. edit*: it's thick plastic so it places well
I think the crying is coming from how somehow you are going to light the plastic on fire and smoke the fumes from it. Unless you have the drill & drill bits to drill into glass you might as well just invest in a glass bong. Enjoy that shit man.
