This project demonstrates how to "hack" energy levels using Gadolinium and its unique Curie point at 20°C (68°F). No batteries, no hidden wires—just pure thermodynamics and magnetic phase shifts.

Can we actually "hack" the energy levels of a marble track to create perpetual-like motion? In this video, I’m pushing the boundaries of engineering by combining a classic marble run with the Curie Point effect.
The Science behind it: By using the unique properties of Gadolinium and precise magnetic fields, this track creates a self-sustaining cycle of motion. When the material reaches its Curie temperature, its magnetic properties change, allowing the ball to be released and pulled back into the cycle. It’s a delicate balance of thermodynamics and magnetism.
