NATIONAL YO-YO DAYEvery year on June 6th, we recognize the fun holiday, National Yo-Yo Day. The day celebrates the iconic stringed toy that generations have enjoyed. June 6th is the perfect day to get out your yo-yo’s and try your hand at The Sleeper, Walk the Dog, Shooting the Moon, Around the World or Hop the Fence. I thought this yo -yo symbolic sign is on any honey singh songs or funny funky steel to cross your fingers and say yo-yo ! Absolutely not .It is believed the yo-yo was first invented in ancient Greece. A Greek vase painting from 500 BC displays a boy playing with a yo-yo.
