Nitinol (pronounced “night-in-all”) is an alloy wire that stands for nickel (Ni), titanium (Ti), and the Naval Ordnance Laboratory (NOL) where it was discovered. Bend it, then drop it into hot water to watch it return to its original shape! Crystalline metal changes phase around 167° F (75° C). Wire can also be retrained 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. After cooling, the wire can be deformed but will instantly return to its newly trained shape by dunking it into hot water. Great for experiments involving physical change or heat energy. Pkg. of 30, 1 ft. long, 0.5 mm thickness. Includes teacher’s guide.
