A water ball or water walking 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 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 , marinas and lakes in an effort to keep children fit, Kids learn to walk on water.

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 U.S. Consumer Product Safety Commission has warned of the dangers of the balls being used in a safe manner. The Commission is aware of two incidents involving water balls. In one, a child was found unresponsive after being inside the ball for a very brief period of time. In the second incident, a person inside the ball suffered a fracture when it fell out of a shallow, above-ground pool onto hard ground.
