The Knowledge
💦 The Rocket Scientist Behind the Super Soaker
Lonnie Johnson, a NASA engineer, invented the Super Soaker, revolutionizing playtime after an accidental water release during an experiment. His success funded clean energy research and education initiatives.
It’s the ultimate summer toy. A backyard classic. A staple of water fights everywhere. But did you know the Super Soaker—one of the best-selling toys of all time—was invented by a NASA scientist?
This week on Forgotten Genius Fridays, part of our short video series The Knowledge, we’re telling the story of Lonnie Johnson, the brilliant engineer behind the water blaster that changed playtime forever.
👨🏾🔬 From Rocket Science to Soaking Wet
In 1982, Lonnie Johnson was working on a heat pump project in his bathroom. A former Air Force officer and NASA engineer, Johnson had already helped develop spacecraft systems, including work on the Galileo mission to Jupiter.
But one day, while experimenting with pressurized water and cooling systems, a valve released—and shot a stream of water across the room. That moment sparked a different kind of idea.
Johnson thought, “This would make a cool toy.”
🧪 The Road to the Super Soaker
Johnson built a prototype of a pressurized water gun unlike anything on the market. After years of rejections from toy companies, he finally licensed the design to Larami Corporation, a small toy maker that saw its potential.
In 1990, the Super Soaker hit store shelves—and exploded in popularity.
Within two years, it had sold over 20 million units, becoming a cultural phenomenon and sparking a line of high-powered water blasters. Eventually, Larami was acquired by Hasbro, which still sells Super Soakers today.
🌍 What Lonnie Johnson Did Next
Instead of just cashing in and disappearing, Johnson reinvested his success. He used Super Soaker royalties—estimated at over $1 billion in sales—to fund research in clean energy, including work on solid-state batteries and solar power.
He also founded the Johnson STEM Activity Center in Atlanta to help underserved students gain hands-on experience in science and technology.
