Memory metal glasses. Time-lapse image of a hand crushing spectacles made from shape memory metal. Memory metals are alloys made from nickel and titanium along with aluminium or copper. Once manufactured in a certain shape the metal may be deformed with little effort, but will quickly regain its shape once released. At room temperature the metal is plastic, so it can return to the structural arrangement in which it was made. This makes the glasses almost unbreakable.
