“When I was at the Jet Propulsion Laboratory back in the early '80s is when I first got the idea. The Super Soaker was based on some engineering principles that I applied. I was actually working on another invention which was a heat pump that would use water as a working fluid instead of Freon… I was working on a heat pump that used water as a working fluid, and I made some jet pumps for it. I accidentally shot a stream of water across a bathroom where I was doing the experiment and thought to myself, ‘This would make a great gun.’” - Lonnie Johnson
