i did make a bendy pipe. that was fun.
i hand carved a wooden bowl with a counter sink and some other random tools. i think connected it to a three foot tube of bendy plastic tubing.
basicly what you get is something similar to the beer bong. you can twist and bend it all you want. its fun for lots of things.

also. roll a joint. Then open a beer. Take a pen and jam it through the top of hte side of the can (not the top top, the sdie top) stick the Joint in, and drink while you smoke.
