Take two people, one Sphere and a sizeable hill and what have you got? This is a fun, extreme activity which will see you writhing around in a spherical universe where the sky is the ground and the ground is the sky and your stomach made a bid for freedom some time ago. You\'ll love it! With no harnesses you are completely free in the Sphere, as you and a friend slip and slide around inside the ball with thirty litres of water. Instead of being thrown around with the ball, link arms with your friend and slide together down a hill, riding the water like a flume.. | Aqua Zorbing Experience for Two
