I just made one of the bongs from that video last week, after seeing it. I used a two liter though!! That thing rips, i would def reccomend. Two rips and you are retarded.
devilman1988 Reviewed by devilman1988 on . Gravity Bongs? Who doesn't like smoking out of gravity bongs? I don't mind them, but they're on the bottom of my list just because so many other methods work so well. One thing that I did see which I want to get since it was like only $20 is a collapseable self contained (looked like an accordian or however it's spelled) gravity bong. It had a bowl stand and it just looked awesome. Anyone ever used one of these yet? Rating: 5
