Heh. I really am saddened by the state of people's homemade bongs nowadays.
Bucket. 2 liter bottle with lid. Ice water. A bowl piece or socket to use as a bowl piece.
Gravity bong!!!!!
I can tell you step by step how to make this if need be. PM me.
Any size soda bottle and a socket or tin foil. Again, I can give step by step instructions.
And no, plastic doesn't melt if you use it for a bowl. (I smoke pot through a plastic pipe all the time.) You don't light it on fire, for Pete's sake. The marijuana goes out quickly if you aren't toking on it... if you make your bowl/bong right. You gotta know how to do it, though. The plastic will scorch and turn black, but not burn.
Wendy, feel free to PM me if you need specifics. Basically if you mention the bucket, bottle and ice water, most people are going to know what kind of gravity bong your character is making. It's so simple a kid can do it. Which is scary, but that's a whole other thread...
