Memory Metal Kit

Type: D, I    |    Level: Al Levels
$25.00

Pull the ends of the ICE memory metal wire to distort it, then watch as it returns to the ICE shape when put into hot water. Our Memory Metal Kit explains how some metals can be bent and will return to their original shape when the temperature is raised because the have been trained to remember a certain shape-which is to say they have a memory.

The ICE Memory Metal Kit includes one piece of memory metal wire (Nitinol™) shaped to spell “ICE”, an eight-page description of the chemistry responsible for shape-memory retention, and many diagrams illustrating the concepts ready for projection.
