Why Lonnie Johnson Invented the Super Soaker
Lonnie Johnson invented the Super Soaker while working on a heat pump system for his NASA-related engineering projects. He discovered the high-pressure water stream by accident when a prototype nozzle failed during a test. Johnson, an American inventor and aerospace engineer, refined the concept into a handheld water gun that used compressed air to shoot a stream of water. The invention became a global commercial success, generating billions in retail sales and establishing Johnson as a prominent independent inventor.

The Super Soaker was first introduced to the market in the early 1990s and quickly became one of the top-selling toys in the United States. Johnson licensed the technology to Larami Corporation, which was later acquired by Hasbro. The toy consistently ranked among the best-selling summer products, with some models achieving iconic status in popular culture. The financial success of the Super Soaker provided Johnson with capital to fund his other inventions and research projects.
