Swingy Thingy - The infinite spiral.The totally crazy and twisted spiral that keeps going. The new mega fun for one or more players! The Swingy Thingy is great with the hand, a string or on the arm and requires a lot of skill from the player. The Swingy Thingy is slipped over like a bangle and rolls up and down the arm. The cheeky funny spiral is reminiscent of a slinky stairlifter.
