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’s quote, “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,'" reflects a moment of innovation that led to the creation of something entirely unexpected. Johnson was working on a scientific experiment related to heat pumps and jet pumps, but his accidental discovery of how water could be propelled across a space sparked the idea of developing a water gun—a moment of serendipity that would later lead to the creation of the popular Super Soaker.

The quote highlights the nature of invention and creativity, where an unexpected result or accident can lead to groundbreaking ideas. Johnson’s observation of the powerful stream of water he created during his experiment led him to think about how this technology could be applied in a new, fun, and commercial way. His insight into how water could be used to create an exciting product is an example of how curiosity and innovation can sometimes turn mistakes into opportunities.

Johnson’s statement also underscores the importance of thinking outside the box. While his original project focused on energy systems, his ability to see the potential for a toy—something as simple as a water gun—demonstrates how an inventive mindset can lead to unexpected innovations. This idea of crossing scientific experimentation with everyday objects was key to his later success.

The origin of the quote comes from Lonnie Johnson, an African American engineer and inventor best known for creating the Super Soaker water gun, one of the best-selling toys of all time. His work on the jet pump that led to the invention of the water gun is a testament to how creativity, hard work, and a willingness to explore new ideas can turn an experiment into an iconic invention.
