Rolling Marble Sculpture: https://www.physicsfunshop.com/search?keywords=rolling marble Marbles perform gymnastics as potential energy of gravity is converted to kinetic energy. An elegantly designed auger conveyor, an Archimedes' Screw, brings the marbles back to the top (powered by an AA battery and a small motor). Conservation of angular momentum produces a simulation of decaying orbits as the marbles whirl down the the main funnel shaped feature. Made with recycled wood by artist Bogdan Krup

Marble Twister: centripetal acceleration keeps the marble on the rails of the coil in this vortex shaped marble run toy. Not enough velocity to keep it all the way down though so it drops down at a certain point. ➡️ 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 #physicsfun #gravitywell #angularmomentum #kinetic #kineticart #kineticenergy #marblerun #vortex #science #scienceisawesome | Physicsfun
