Let me just throw it out there that my bong hits harder and smoother than any Roor I have tried. Double perc glass on glass with a carbon filter and diffuser on the first stem. The whole thing is fumed, too. So it looks real pretty in the sunlight. Type 'young man in bali garly bowl' to see it in action. The video is called trendy sillouhette or something, look for my name
The video? Yes I made that myself. The bong, I bought for about $350 then added about $150 worth of upgrades.
Oh okay, thought you meant the bong was homemade. I would have been very impressed. What were the upgrades?
You pull the smoke through water, which catches all the ash and most of the tar. So it cleans up the smoke a lot. It also condenses the smoke so you can inhale more smoke at one time than you could with a pipe or joint.
