Hands-On Basketball is a basketball that shows children where to place their hands when playing the game. Chris Hass was just nine years old in 1994 when he came up with the idea for the basketball after watching friends miss easy shots.

He went on to develop his idea for Hands-On Basketball for an Invention Convention competition that was held at his school. Even though he didn’t win, his teachers encouraged him to get a patent. Then, with the help of his dad, he sold the exclusive manufacturing and selling rights for Hands-On Basketball to a sport equipment company, which has since sold hundreds of thousands of the basketballs around the world.
