The simplest water bottle holder

Sometimes the simplest ideas are the best ones, although I'm not sure about this one. Pretty much everybody these days needs to drink more water, and this is one way you could encourage yourself to do that: hook the water right on your belt. This bottle holder would probably be great for anybody who does a lot of walking and moving around during the day (think college kids, and adults who don't use an office or have a desk at their job), and of course it could work great for walking or jogging also, and even for travel and vacations. Except one concern: even while walking won't it bounce and bang around and get annoying?
