for awhile my buddy had a really nice pipe, fit .5 and hit really smoothly but he broke that, so we started making bongs. this one we made was simple, but probably one of the better DIY bongs around because its fully made of metal, therefore not breaking or squishing in transport. started with an old metal water bottle punched a hole for a stem, we found a metal stem, electrical tape to make it air tight, then used a half inch ratchet peice for a bowl, taping that as well to the stem. she's yet to be named but a little bit of water and you can take some of the biggest hits off her. i'll post more as i go about making them
