In this video I show you how to make a gallium beating heart. I show you the reaction that happens when you add gallium to sulfuric acid and then touch iron to the beaded up gallium. It causes a pulsing action due to the surface of the gallium reacting with the sulfuric acid and then reversing once it touches the iron.
