Abstract
In accordance with the invention, thin bodies of plastic, such as sheets or strands, with substantially different thermal coefficients of expansion are laminated together to make plastic bodies which move in response to heat. The movable plastic bodies can be secured to a suitable base to make a variety of devices for amusement, temperature monitoring and display. Applications for amusement include a thermally blooming flower, a solar activated butterfly, and curling hair for a doll. Applications for temperature monitoring include safety lids for drinking cups, sunlight blockers and ventilators.
