yeah, waterfalls are fun...and definitely unique.

I took a cap from a 2L bottle of pop, and drilled/bored/chewed/melted a hole big enough to actually EMBED the bowl into it. Now I've got a small, portable smoking device that can be used for any of these devices! In a pinch, you can use it just as a tiny pipe, too. But make sure there's a permanent screen in it.
