i once made a dual perculation bong/hookah with an ice chamber, i made it from like 4 or 5 bottles and some tubing, the bowl was the slide from my glass bong.
that shit looks like a jetpack and smokes like a chimney but its so much work to fill with water and ice i havent used it in months.
Metaphor Reviewed by Metaphor on . Unusual or Inventive Bongs My fave is a melon bong Place one melon in the freezer for around 15 to 20 minutes, don't forget it's there because it's a bastard to cut when it's frozen solid. Cut off the top and hollow out the melon, watch your fingers with that knife. LOL Using a stem pipe make two holes in the top. Sieve the inside of the melon to get rid of the seeds add a little water and half fill the hollowed out melon , add some ice cubes too.. Rating: 5
