When was Wiffle Ball invented?
Back in 1953, a man by the name of David N. Mullany was watching his son play a game with his friends in their backyard. The game looked very similar to baseball, but they were using a perforated plastic golf ball and a broomstick as the bat. That’s when Mullany first came up with the idea for Wiffle Ball. He allowed his son and friends to test out several prototypes before settling on the final design. Source: Mentalfloss.com
