Are there materials that “remember” their shapes such as the ones seen on television?

Believe it or not, the answer to this question is yes! Shape-memory alloys are alloys that have the ability to “remember” their original shape (which means that they return to their original form after a deformation). This effect is a result of the material’s unique crystal structures, which allows it to reverse after a deformation. Shape-memory alloys have a wide domain of applications (tweezers used to remove foreign objects), ranging from medical appliances to military technology and even into clothing!!!
