Magic Part 3 – Memory Wire

This wire has a better memory than I do.

This is cool stuff. It’s called memory wire, or more specifically, nitinol wire. To perform this trick, I “programmed” the wire by bending it into the shape of the word “LIME.” Then I heated the wire using a butane flame. It took a while, but when I was all done, I could bend the wire into any shape and then just put it in hot water and I get the word “LIME” right back! Scientists are finding way to create motors using the heating and cooling properties of nitinol.
