Nitinol (pronounced 'night-in-all') is an alloy metal that stands for Nickel (Ni), Titanium (Ti), and the 'NOL' stands for the Naval Ordinance Laboratory where it was discovered. Bend it, then drop it into hot water and watch it return to its original shape! This crystalline metal changes phase around 75°C (167°F). You can also retrain this wire by annealing it. First bend it into the desired shape, heat it to a dull red glow along the entire length then cool it by immersing it in water.
