Sproing is the amusing, entertaining spring thing!
Watch this amazing spring move, bounce, and walk before your eyes. The retro feel of this premium metal spring makes for endless nostalgic play.
Just place it at the top of the stairs, or any high surface, and watch it go!  You can also "juggle" or "walk" or "yo-yo" the amazing Sproing.
Sproing is approximately 2.5" in circumference  and can stretch to nearly 5 feet!
