This is the only pogo stick designed for use in swimming pools that allows you to perform a variety of waterborne stunts as you bounce off walls or bottoms. A rigid ball filled with water fits into the non-slip footrest, providing responsive push-off when compressed against a pool's floor with your body weight, enabling you to splash effortlessly in shallower water and bound powerfully through deeper water. The stick is made from heavy-duty ABS plastic with two rubber handlebars for a firm grip. For use with in-ground pools with solid surfaces
Oh man, just imagine
the hours of enjoyment actually having a good time playing with this thing. Impossible, isn't it? It is. And so is looking into my eyes and not getting wet.
