Memory Metal Wire, ICE-Shaped

Memory Metal Wire, ICE-Shaped

Type: D, I    |    Level: Al Levels

Some metal alloys have shape-memory retention—that is, they can be bent and will return to their original shape when the temperature is raised. Pull the ends of the pre-shaped wire to distort it, then watch as it returns to the ICE shape when put into warm water.

This ICE-shaped memory metal is also available as part of the Memory Metal KitThe Memory Metal Kit includes an eight-page description of the chemistry responsible for shape-memory retention, many diagrams (ready for overhead projection), and a sample of ­memory metal wire (Nitinol™) in the shape of ICE.
