Nitinol Wire - 1ft

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.  After cooling, the wire can be deformed but will instantly return to its newly trained shape by dunking it into hot water!  Great physics demonstration for the classroom, and even makes a fun gift for practically anyone who admires the 'magic' of science.

Features:

• Alloy metal wire consisting of Nickel and Titanium
• Returns to its original shape, in spite of bending, when dropped in hot water
• Can be retrained to take on a new default shape
• Great physics experiment for science teachers
• Can be used by students for science fair projects
• Wire is approximately 1 ft in length when stretched out
