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

Toy Themed Rolling Marble Sculpture: marbles perform gymnastics as potential energy of gravity is converted to kinetic energy. This festive FAO Schwarz branded marble run features two powered conveyers including an Archimedean screw inside the toy rocket (one AAA battery and a small motor for each). Found and repaired this one from a local thrift store. ➡️ Follow the link in my profile for info on where to get rolling marble toys and other amazing items featured here on @physicsfun #physicstoy #
