On May 27, 1986, the U.S. Patent Office grants a patent to African American inventor Lonnie Johnson for his toy design simply titled ”Squirt Gun.” After a few name changes and additional patents, Johnson’s invention—ultimately re-named the “Super Soaker®”—would become the best-selling water toy of all time, eventually earning its rightful place in the American National Toy Hall of Fame.
