who invented super soaker

The Super Soaker was invented by engineer Lonnie Johnson in 1989. He conceived the idea while working on a different scientific project in which he was experimenting with a refrigeration system using water instead of Freon. He built the first prototype using PVC pipe, acrylic glass, and a plastic soda bottle, and later licensed the invention to the toy company Larami, which released it commercially in 1990 (initially called the Power Drencher, later renamed Super Soaker in 1991). Lonnie Johnson is also known for holding over 100 patents and has worked as an engineer for NASA and the U.S. Air Force.
