Description
What do elephants and nitinol wire have in common? A good memory! Introduce students to a shape memory alloy that changes phase around 50° C and can be heat-treated to "remember" a certain shape. Then challenge students to explain the contradiction with metal properties when a straight piece of wire dropped in hot water contracts (not expands) to form a new shape. We recommend using a minimum of 3 to 5 inches of wire for demonstrations.
