… nitinol wire is a wire that will remember a shape that you tell it to. You can deform the wire. Then when you heat it up it goes back to its remembered shape on its own. In the photos below I’ve made it remember the shape of a compressed coil by putting it in a candle flame. I then stretch it out, and when I heat it by passing electricity through it, it returns to the compressed coil shape.
