SUPER SOAKER
Inventor: Lonnie Johnson
Year Invented: 1982
In 1982, a NASA engineer named Lonnie Johnson was trying to create a new type of heat pump—a device that uses water to transfer heat. Suddenly, his creation sprang a leak. A burst of water shot out of a nozzle. Johnson thought: This would make a great toy! He built a prototype, or model, of a high-powered water gun using Plexiglas, plastic PVC piping, and a two-liter soda bottle. The Super Soaker was born!
Before the invention of the Super Soaker, squirt guns were fairly underwhelming, says Bensch. “When I was growing up in the 1960s, squirt guns were more likely to dribble water down to your elbow than to actually douse the friend you were aiming at,” he adds. But Johnson’s version created a powerful spray. It worked by building pressure, or force exerted on an object, inside the gun.
Water sits in the top chamber of the Super Soaker. Pumping the handle on the front of the water gun pushes air into the chamber, increasing the pressure on the liquid. When a person pulls the trigger, water blasts out at up to 15 meters (50 feet) per second. Today, water squirters come in all shapes and sizes— but the Super Soaker still reigns supreme.
