I also experimented with the nitinol the chromatography group is using. Nitinol is memory metal that straightens out when placed in heat. I twisted the nitinol wire’s ends together and poured warm water over the wire. It quickly sprung up and landed about six feet away. I think it was because the ends untied so quickly in an attempt to straighten out that it hit against the bottom of the surface hard enough to leap into the air like a speeding gazelle.
