therein". The Super Soaker used a water chamber on top of the gun, that was detachable for filling. The revenue that Johnson received from the Super Soaker licensing provided enough money for him to create Johnson Research & Development Co., Inc. Technology Piston pumper Piston water guns have been produced for many years. These guns do not have triggers; they are fired simply by pumping. Although this design feature allows them to reload rapidly, piston pumpers tend to have less range and less power than other designs. Air pressure with pressurized reservoir Originally made popular by the Super Soaker 50, pressurized reservoir systems are still common for small water guns. A water gun using this system is pressurized by air being pumped and compressed into its reservoir. When the trigger is pulled, a valve is opened and the compressed air pushes the water out of the nozzle. Super Soaker started with two pressurized reservoir water guns, and has continued to produce them in various shapes and sizes. Air pressure with separate chamber This is a more powerful air pressure system that was also first introduced by Super Soaker. It is designed so that water is pumped from the reservoir into an empty plastic container. As the water is pumped in, the air sitting inside becomes compressed. When the trigger is pulled, the valve opens and the compressed air forces the water out. The brand first used separate air pressure in 1991 on the Super Soaker 100 and has since used the technology in many other water guns. Spring-powered Super Soaker has made a few spring-powered water guns. They first made the Quick Blast in 2008. The Quick Blast was a triggerless gun which functioned similarly to piston pumpers, but had a spring-loaded piston inside. The Quick Blast had a firing valve, which automatically opened once a certain pressure was reached. The spring would then push the water out the nozzle. The Super Soaker Shot Blast, released in 2010, used a system nearly identical to the Quick Blast with different styling. In 2013, Super Soaker produced the Flash Blast. While this blaster was spring-powered, this pistol-sized blaster used a system different from the previous two. Its slide was cocked back once. Then the trigger was pulled, firing a short stream of water. Function of this gun is similar to Nerf guns. Motorized Super Soaker later made many motorized water guns. In
