Spirelli Toy: very simple kinetic art toy that utilizes the interplay of potential energy of gravity and conservation of angular momentum- basically a wave train of tiny hula hoops! The note you hear comes from the wire resonating due to excitation when the hoops are rotating fast enough and at the right rate. ➡️ Follow the link in my profile for more info on where to get this and other amazing items featured here on @physicsfun #physics #physicstoy #gravity #potentialenergy #angularmomentum #ki
