Can a Metal Coil Remember Its Shape?
Shape memory alloys are alloys that can retain their original shape after being deformed by undergoing a temperature change or mechanical straining. In this video, see the shape memory effect in action.
First, we bend and deform a coil made out of a popular shape memory alloy, nitinol (nickel-titanium). Watch what happens when we drop it into hot water...
