The Dancing Pea
A pea can be made to dance on a column of air as you sometimes see a rubber ball rising and falling in a fountain of water. Take a piece of a clay pipe about three inches long, and make one end into a little rounded cup, by cutting the clay carefully with a knife or file. Then run two small pins cross-wise through a big, round pea, put the end of one pin in the pipe and hold the pipe in an upright position over your mouth. Blow gently through the pipe and the pea will dance up and down.
The Glass-Maker
Another trick to play with pins is the glass-making pin. Cut an ordinary rubber band in two, and stick a bent pin through the middle of this. Now hold an end of the elastic in each hand and whirl it rapidly around, stretching it a little. The revolving pin will at once assume the appearance of a tiny glass vase, or tumbler, and the shape can be varied at will. It is best to have a strong ray of light on the pin and the rest of the room darkened.

Electricity
Various tricks can be played by means of the electricity in paper. Ordinary sealing wax, rubbed briskly on a coat-sleeve until it is warm will attract bits of tissue paper, or any other soft paper. A variation on jack-straws can be played by means of this trick. Tiny scraps of tissue paper, each numbered, are piled in the centre of the table and each player by means of a piece of sealing wax tries to draw out the greatest number in the shortest time. This is a fascinating game and arranged impromptu in a very short time. The pieces of paper need not be of tissue paper, as any very thin paper will do. They should be about a quarter of an inch wide by an inch long and numbered up to twenty. They must be removed from the centre pile and put in piles before the players without touching with the fingers. It will be found that shaking them off the sealing wax is often harder than making them stick to it. Of course an effort should be made to secure those pieces of paper which have the largest numbers on them, as a few of these count more than many of the others.
Electric dancers are easy to make. Cut little figures out of tissue paper and lay them on the table. Put on each side of them two books and lay a sheet of glass over them about an inch and a half above them. Rub the glass briskly with a flannel cloth and they will jump up and down.
