Gel-Bot water bottle

This is the Gel-Bot, brought to you by Hydrapak (the company that makesthose nifty backpacks with the integrated water packs). It combines awater reservoir and an energy gel reservoir in the same bottle, and bymoving the drinking valve in or out and squeezing, you can switchbetween water and gel without using your hands.
