As much as I appreciate quick access to liquid refreshment on rides and hikes, I've got a hate-hate relationship with the water bottle. For one, the water ends up tasting like plastic. And then there's mold. Clean Bottle is an engenious new design that can eliminate the latter. The invention is a dead simple "why didn't I think of that" idea: the top and bottom both unscrew to give you access to clean. Good news for thirsty humans, bad news for mold spores. Check out the video, with none other than Gary Fisher giving his stamp of approval.
