Nickel Titanium Alloy (55% Ni 45% Ti) is a member of a group of metal alloys known as "Shape Memory" alloys. These are alloys that "remember" the shape that they once were.
Manufacturers also make glasses out of such metals, to allow them to bend like normal when you sit on them by accident because your kid put them on the chair instead of the table! Wait, that's not the special part, it's when you get up out of the chair, the glasses pop right back into the shape they're supposed to be instead of remaining a mangled mess.
Could you imagine valve springs made out of this stuff? (I know, pricey)
Anyway, on to the videos!
