Water Ball Zorbing

A water ball is a large inflatable sphere that allows a person inside it to walk across the surface of a body of water. The giant ball is usually two metres in diameter and has a zippered entrance to allow for easy entry and exit. The water ball is similar to the zorb, but it has only one layer and is designed for water travel rather than down-hill rolling. In the United Kingdom, the balls have been used at swimming pools, marinas and lakes in an effort to keep children fit.
The concept dates back to at least 1985, when a water ball appeared in the Beach Boys music video Getcha Back. Charles Jones from Oklahoma developed a water ball commercially in 1998. He was invited by a British reporter to visit London to demonstrate the ball on a lake. As soon as he attempted to walk across the water, he lost his balance and fell. The ball deflated and filled rapidly with icy water. He was saved from sinking below the surface when an assistant dragged the ball back to dry land using a safety line, witnessed by a crowd of tourists.
The United States Government has warned of the dangers of using the balls, saying it "does not know of any safe way" to avoid the dangers of suffocation and drowning, among other hazards. There are recorded instances of children fainting and crashing onto hard surfaces while inside the balls, and the U.S. Consumer Product Safety Commission has encouraged amusement ride officials not to allow their use. The Commission chairman declared an intention to pursue the safety investigation further.
