Swinging Sticks: What are they? Here to offer an alternative to the swinging orbs of Newton\'s Cradle, these swinging sticks will have you mesmerised. About the product Perfectly balanced, these sticks use gravity, weight, and momentum to stay in motion. Just insert 4 x AA batteries and you\'re good to go. They look so awesome on a desk, they even stole a scene from Robert Downey Jr in Iron Man 2! Why you should buy it Their hypnotic motion is curiously calming, plus they make a desktop display that\'s definitely worth remarking on! | The Swinging Sticks Mini Toy 2.0
