The [wiffle] ball used in the game was invented by David N. Mullany at his home in Fairfield, Connecticut in 1953 when he designed a ball that curved easily for his 12-year-old son. It was named when his son and his friends would refer to a strikeout as a “whiff”.
A classic wiffle ball is about the same size as a regulation baseball, but is hollow plastic no more than 1/8 inch thick. One hemisphere is perforated with eight .75-inch oblong holes, with a solid second hemisphere. This construction allows pitchers to throw a tremendous variety and size of curveballs, sinkers, and risers. Wiffle balls are typically packaged with a hollow, hard plastic, yellow bat that measures 32 inches in length and about 1.25 inches in diameter.
Greatest. Invention. Of. All. Time. I spent my ute playing wiffle ball with my friends in my driveway. The best part was hitting a ball so hard it slammed into the douchey next-door neighbor’s car. Frak that crazy old coot.
