Tornado Top is the 3D printed spinning top that could spin forever... it's designed to work like a turbine so as long as you blow on it every few minutes it will never stop spinning! There's nothing quite like it any where else. Blowing through a straw is more than enough power to get this top roaring with speed. It's incredibly fun and easy to do. Even a bad spin will level out as it accelerates. So what are you waiting for?
