Waboba

Waboba is an international outdoor toy and sporting goods brand headquartered in Stockholm, Sweden with offices in Atlanta, Georgia and Guangzhou, China.

[2] To date, there are 10 different types of Waboba balls (Pro, Extreme, Surf, Blast, Zoobers, Big Kahuna, Tides, Sol, Zag, and Fetch for dogs).

[4] On April 1, 2016 Waboba was featured on The History Channels' Million Dollar Genius for Jan von Heland's invention of the ball that bounces on water.

A shallow impact with the water surface creates a bowl-shaped depression that launches the stone into the air as it leaves.

[15] He had been inspired by the story of a technique historically used by the British navy that bounced spherical cannon balls off the ocean surface to achieve accurate hits against enemy ships.

Wallace worked out the physics by bouncing marbles, steel spheres, and various sizes and shapes of balls across a pond and then a long trough before progressing to larger-scale experiments.
