Abstract: A color-changeable toy having a toy body to which a quasi-reversible thermochromic material is applied in a pattern. This material stably holds either of two colored states in a range of ordinary room temperatures. However, the material reversibly changes to one of the states above this range and to the other below this range.

A breath blow pipe can be used in conjunction with the toy and have an external appearance associated with that of the toy, e.g., gun and soldier.

Abstract: This invention provides a toy vehicle incorporating actuators made from a shape memory alloy material. These actuators may be in the form of a spring, wire or similar form that has a mechanical response upon the application or removal of heat. In particular, wires may be connected about hinges for doors, hoods, convertible roofs and other such items which, upon the application of heat to the wire of shape memory ally, causes contraction of the wire and rotation about the hinged joint of the body part. As such shape memory ally actuators are generally only operable in a single direction, they may be provided in pairs or in opposition to another biasing means to cause the opposed rotation about the joint when desired. The preferred source of heat to the shape memory alloy actuators is through the provision of electrical energy to the wire to create heat through the resistance of the shape memory alloy actuator itself.

Abstract: In accordance with the invention, a hollow, gas-containing diving body is disposed in a partially shaded transparent column partially-filled with a clear liquid. The diver is weighted for near-neutral buoyancy. The upper portion of the column is shaded, and the lower portion is subjected to thermal radiation such as sunlight.
