Step 1: Material List
Metal tweezers or clamps of some sort
Water and container
Rod for a spiral, anything else you would need for different shapes
Body heat or battery holder pack
Nitinol wire, ($20 to $30 per meter)
Step 2: Annealing Explination
Annealing the wire is the same type of annealing that is used for all other metals, as well as glass. The material is brought to a temperature that allows the atoms to relax and rearrange, but not too hot as to deform or melt. A way to anneal wire is to heat it to a dull red glow along the entire length, and then quench it by putting it into water. It would be a good idea to find a container that will fit your metal, I used a bread pan. It is also possible to anneal the wire while it is looped, although it will try to straighten out at first. It is not necessary to use a pickle, for you jewelry smiths out there, although it would help to clean the wire. I chose not to, simply because I do not have the setup for that.
