A toy ball, preferably a football, that emits light and bomb-emulating sounds when spiraled. It comprises a foam body defining a central bore with open ends, conical end caps associated with the ends, and an electronic circuit responsive to a centrifugal switch. The circuit and its battery are fitted within a tubular canister, preferably coaxially disposed in the bore. Rubber tethers suspend the canister between the end caps. A D-ring bracket flexibly connects one end of each tether to the canister. An S-hook connects the other tether end to an end cap. When the ball spirals during flight, a sound simulating a bomb dropped from an aircraft is emitted from piezoceramic transducers mounted on the lids of the canister. Sound horns extend from the transducers to the end caps to conduct the sound. Radially spaced apart light emitting diodes mounted in recesses in the outer surface of the ball are activated by the circuit. The centrifugal switch is responsive to rotation of the ball about its longitudinal axis, as created by a spiral pass. The tethers and end caps facilitate service of the components in the central bore. The foam may be compressed and an end cap unhooked from the suspension system to allow access to the transducers or the circuit canister.
