This is Fontus, The first Self-Filling Water Bottle. If you, or someone you know is the outdoors’y type. This is defiently going to be for them. How it works is you strap it into the holster, which is made to fit perfectly under your bike so it straps in with you. IT collects condensation and uses Solar power to fill the bottle so even if you drink the whole thing, it will refill itself within minutes. So you will never go thirsty on the trail again. I bet people stranded on an island wish they had something like this.
