Hey guys, I've got a decent collection of pipes and bongs so I don't really need to do the homemade thing anymore, but sometimes I still do just for fun. All it is is a bamboo branch that i snapped off. Then I cut both ends to make sure the hollow part wasn't blocked. Then I stuck a knife in one end and twisted it around to make a bowl. Then I blew out the dust, ran it through some water in the sink, dried it and pushed the bowl down in to some fresh-ground bud. Hit shockingly well for such quick construction. Enjoy There appears to be two of them because I'm holding it by a mirror.
Tragically you do occasionally get a bit of bamboo taste, but only if you torch it. And what you're seeing may be a bit of resin because I used it right after I made it, then took this picture after i came inside to refill it.
