I hate the sensation of smoking so I avoid it all together, but when I see a cool product I can't help recommending it. Apparently this is an inflatable water pipe aka hookah. As seen on "Cheech and Chong Have a Pool Party".

This is seriously genius! The problems with a bong are two things, one you can break it really easy and two it's hard to travel with. Blow up a bong? How great is that! And you can't beat the price.
