Take another empty spool and stick a common wire hairpin partially into the hole, bend the hairpin slightly down against the edges of the hole, do the same with three more hairpins, and you will have a spool with a funnel-like opening of hairpins at the top ([Fig. 84]). In the funnel place a small, light-weight ball made of a crushed bit of bright paper wound around with thread. Raise the spool to your lips and blow gently ([Fig. 85]). The ball will rise and fall in mid-air, in the same way that you have seen one of rubber dance at the top of a small fountain or jet of water.
