Abstract
A gyroscopic diving toy is comprised of a housing and a motor positioned inside the housing. A battery compartment is arranged adjacent the motor for receiving a battery. A swim bladder and a ballast are arranged inside the housing to provide neutral buoyancy and balance. A propeller is attached to an axle of the motor protruding through the housing. The axle of the motor is coaxial with a longitudinal spin axis of the housing. The housing is generally circular about the spin axis for minimizing drag when spinning. When the motor is activated, the housing is spun rapidly in a direction opposite to the rotation of the propeller, and gyroscopic forces generated by the rotation of the housing cause the toy to repeatedly dive and surface automatically for amusement.
