The Rocket Scientist behind the Super Soaker
It is not generally advisable to spout a stream of water across a boardroom filled with executives. However, Lonnie
Johnson—NASA engineer, inventor, and creator of the Super Soaker—delighted the president of toy company
Larami Corp. with this very display. In 1989, after a seven-year trudge through failed patents and rejections, Johnson
finally got his Super Soaker to store 1 shelves where it reigned as the most popular water gun toy of the 1990s. His
product and 2 it’s spinoffs still predominate that market today. A combination of luck and perseverance contributed to
Johnson’s successful creation.
[1] The discovery that 3 ended up eventually leadingJohnson to his first Super Soaker model was
serendipitous.[2] At the time, Johnson’s day job was at NASA’s Jet Propulsion Laboratory, where he helped design
an atomic battery for Galileo, a spacecraft created to observe Jupiter.[3] By night, Johnson explored his own
inventions in his home office. [4] Johnson’s prototype sported a long plastic tube and a metal spigot. [5] He aimed it
at the bathtub, and the powerful torrent of water it yielded put him 4 at mind of a high-powered water gun. [6] The
next step—an arduous one—was to find a company with the desire and means to produce it. [7] 5 After expressing
initial interest, Johnson was dismayed when one toy company ended negotiations. [8] The next company he
approached went bankrupt. [9] He persisted and, after Johnson’s interactive display in that boardroom, Larami Corp.
bought the Super Soaker and created fourteen different models of water guns based on his design. [10] A decade
later, over 200 million Super Soakers had sold, generating over $400 million in revenue. 6
7 Johnson’s physics and engineering skills were critical to his toy design. Traditional water guns are held in one hand
and require just a trigger pull to eject the water from a small cavity. Johnson’s invention, 8 by contrast,calls for more
muscle, requiring two hands to operate an air pump before discharging, and stores water in a larger container. The
pump action on the Super Soaker allows the user to compress the water and store more energy, resulting in a mighty
cascade of water.
While he enjoyed the accomplishment of creating this product, Johnson also sought to solve problems more complex
than 9 amending summer fun. He embarked on his own 10 business. He founded Johnson Research and
Development with his Super Soaker proceeds. He owns over 80 patents, and his main goal is to create more viable
options for renewable energy. Johnson’s 11 persistence knowledge and a happy accident paved the way for his
success as an independent inventor.
