off a third of the length of a ribbon spool for E, and fasten another spool (D) to the top of the pencil. Spool D should be glued fast to the pencil, and the spool-end E should turn loosely upon it. Coat the lower part of the pencil with glue so it will stick fast in B.

How the Top Spins. When you have made this much of the top, spin it to see how it works.

To get the best results, the cardboard used for the disk platform must be very straight. If it warps, flatten it by pressing it under a pile of books.
