Introduction: Muscle Wire (Nitinol) in HOT Water

Sometimes called the Smart Alloy, Muscle Wire or Memory Metal, is an alloy that "remembers" it shape. You can reshape the wire, but when heated it returns to the preset shape. Ever wonder how someone bends a spoon with their mind? Same metal.

I've herd of this stuff it seems really cool but i have 1 question how do u get it into that original shape is there any way i can buy a roll of this wire and say shape it into some random shape so that it always returns to that set shape its a little hard to explain :/ just how do i set the original shape?

Try bending it in the hot water, that might work.
