Meet the Poolcandy Tube Runner: a motorized water float for lakes. pools, and other bodies of water. It has a 3-blade propeller that moves you through the water as you relax. It has a 360-degree controller, so you can spin and move in every direction at the touch of a button.
This motorized float is battery powered (6D). It has a fully enclosed propeller for safety. You can find out more about it here.
