Yes, it’s true! It’s National Yo-Yo Day, a day to pull out your favorite old toy and see if you can still “walk the dog.” Why June 6th? It was the birthday of Donald F. Duncan Sr., who popularized the yo-yo in America in the early 1900’s. However, it is believed that yo-yos have been around for thousands of years, and they might have been used in Ancient Greece! Whether or not you have a yo-yo, celebrate your inner child today, and do something purely fun that will make you smile.
