Memory Wire Experiment

Memory Wire. This wire is amazingly cool – a wire that, no matter how you shape it, when heated will instantly spring back to straight. It’s called Nitinol Wire, which is alloy of 50% Nickel and 50% Titanium also called memory wire.

 

This metal changes phase around 50oC. Bend it, then drop it into hot water and watch it return to its original shape! Can be set into different shapes by heating with a candle flame.
