23. Lonnie Johnson (1949-present)
Notable invention: The Power Drencher a.k.a. the Super Soaker
The Super Soaker wasn't exactly what we would call groundbreaking, but it was definitely one of the most innovative novelties created during the early 1990s. Lonnie Johnson’s plastic water cannon had kids and grown-ups drenching each other silly with H20 on every front lawn and playground across the nation, raking in more than 1 billion in sales and cementing its place in pop culture as one of the most beloved toys of our generation.
