Nitinol is an alloy (nickel titanium) also called memory wire that can be programmed to a shape and go back to it. In this video which is a follow up on a earlier video I expand the test for the nitinol paperclip, spring and spoon. I also do 2 nitinol races between the nitinol spring and paperclip.
My first video was in the daily dose of internet as the smarters paperclip and I got a lot of questions there. Some of them will be answered in this video.
