Buying a pipe? If so then I must agree. Since then I've bought four and made two out of small plumbing parts from Home Depot XD I will be buying a bong from a friend soon, and it'll be the first one I've owned so I'm excited.
Agreed. They cost from $12 to $130, depending on size and colors, design, etc. (obv) More economical than smoking from a rolled one, at least so it seems.
Pipes are easy to make, as are bongs. I've only done a bong once, and it was pretty rad, the smoke was barely warm.
Stupid idea:
I wonder what it'd be like if you made your own, and plugged it into a pump, 80mm cpu radiator with an 80mm fan. (or even 120mm). Heh, maybe even a battery pack, although I dunno how feasible it is to do that by battery-- a dc transformer might be the best idea.
Anyway, a piece is definitely worth it, and kinda honestly, if you cant afford one, why the fuck are you smoking? lol
