ventureDESIGNworks of California has launched the Gel-Bot, a sports bottle that provides access to both water and energy gel in one container.
The gel is housed inside the 'Energy-Core', a piston-like device attached to the water bottle cap that is filled with gel before activity. To access the gel, squeeze the bottle with the cap valve pressed in. To drink water, pull out the valve and squeeze, just like any standard water bottle.
Gel-Bot holds up to 24 ounces of water and 3.2 ounces of energy gel.
