Y is for Yo-Yo (A-Z Challenge)

I bet we've all had a toy Yo-Yo as a child and it seems like such a modern thing to have. But did you know that Yo-Yo's go back a very long way? This picture is of a Greek vase from around 500 BC. It is thought that it shows a boy playing with a Yo-Yo made of terracotta. Other toys were made of wood or metal in those days and some terracotta disks were used for ceremonial reasons. It's amazing what you learn doing the A-Z Challenge! Tomorrow is the final day. Looking forward to Z.
