This invention relates to a toy for active children. It consists of four major parts: a grooved handle, a housing unit resembling a chute, a roller or dowel and a small wheel or disc approximately eight inches in diameter. The wheel or disc and its function, become the principle object of this related toy. The wheel is without attachments and is separately set in revolving motion on the ground, as later described in the preferred embodiment. With the remaining major parts assembled, this device is brought to use grip in hand at the rear of the revolving wheel, simultaneously roller or dowel is brought in contact with rim of revolving wheel. When such contract is made, a constant pressure in nudging fashion is maintained at this point, thus forcing wheel to continue revolving forward along a selected route. Guide panels of former mentioned chute aid in guiding and balancing the wheel in its forward revolving motion, while participant increases or decreases rate of pace. Maintaining wheel in balance and continually revolving forward without faltering, reflects the skill of the participants.

A piston top-dead-center detector includes an adapter capable of being screwed into a sparkplug hole in an internal combustion engine, a length of electrically insulating hollow tubing disposed within a hollow interior in the adapter and a conductive rod slidably disposed within the tubing so as to be slidable relative to the adapter. With the adapter installed in a sparkplug hole, the end of the rod outside of the internal combustion engine is coupled to the positive terminal of the engine coil through a lamp. The engine is rotated so that the corresponding piston in the sparkplug hole in which the adapter is installed engages the end of the rod within the engine and pushes the rod within the insulating tubing in the adapter to an extreme position at the top-dead-center position of the piston. Thereafter, when the piston again reaches the top-dead-center position the electrically grounded piston contacts the conductive rod to complete a circuit from the positive coil terminal and thereby illuminate the lamp to designate the top-dead-center piston position.
