Nitinol is mostly half nickel and half titanium. The best part is that you can do all sorts of nifty tricks with it once you know what you are working with.
By applying a heat source to metal wire we can make it spring back into place. We can even make our own shapes with it using the same method.
In order to set a shape to nitinol you need to torch it up to 600 degrees C, once this is done it will always jump back into place with the proper heat.
