Try a 5 gallon water jug and a doughboy pool. Now that's a friggin gravity bong!!. Jump off the deck and try to land with your mouth on the opening. It is a total waste of weed as probably 10 percent of the smoke in a full load go into your lungs and the remaining 90 get shot out the sides of your mouth. Sure is alot of fun though. It's harder than it seems to land right on the mouthpiece too. Also a friend who was partaking with us cut his bottom lip.
