    • A scarecrow includes a scarecrow body corresponding generally in shape to a body of a live animal; and an assembled and balanced hollow head of molded plastic construction corresponding in shape to a head of the live animal. The assembled and balanced head includes a front face portion and a rear head portion fixed together to form the head. The front face portion has a first thickness and the rear head portion has a second thickness, the front face portion and the rear head portion being unequal in weight, with the rear head portion having selected areas on an interior surface thereof that are thicker than the first thickness and define an offset weight so that the assembled head is substantially balanced as assembled. An unstable mount is disposed between the body and the head onto which the head is rotatably mounted for 360-degree movement of the head to the body without interfering with free movement of the head, the head being balanced on the unstable mount.

    • An inflatable device, having an air flow path having a circumference and including an air diverter comprising a central motor receiver and a plurality of air deflectors extending radially from the motor receiver and located to define a plurality of air flow chambers surrounding the motor receiver; a motor mounted within the central motor receiver and having an output shaft rotatable by the motor and extending below the air diverter, the motor generating heat during use of the motor; a fan connected to the output shaft of the motor and located below the air diverter for rotating in response to rotation of the output shaft by the motor to generate a flow of air, the air diverter cooperating with the flow of air generated by the fan to create a turbulent air flow directed to flow through the air flow chambers and past the motor, the flow of air providing cooling to dissipate heat from the motor; and an inflatable body in flow communication with the air flow path and located above the air diverter for receiving the turbulent air flow. The inflatable body undulates in response to receiving the turbulent air flow.
