Clock Wheel Tops. A splendid spinner can be made of the little balance-wheel of a broken clock (Fig. 119). This little wheel is so accurately made that it will spin very steadily from a minute and one-half to two minutes.

As the ends of this wheel's axle are pointed, the top will stand in one spot as long as it spins.
The toothed wheel shown in Fig. 120, or any of the other forms of wheels from a clockwork will make good spinners, yet, unless you file their pivot ends to points, they will not spin in one spot but will glide and hop over the table in spirals. The friction thus produced decreases the length of time that they will spin, but makes them none the less
