This is an excellent device for those who enjoy fortunetelling schemes.
There are four discs and they all have to be cut out. While doing this
care must be taken to preserve all the projections intact. Note that
the white center of each disc must be removed. This is fairly easy to
do if a pointed pencil is pushed carefully through the paper.
When the four shapes are ready for use, slip them on to a long pencil,
so near together that they are almost touching. See to it that the
disc bearing the lucky devices is fitted on last. It will then hide
the three others. The game consists in revolving the discs and, while
they are turning, there is a likelihood that they will spread out on
the pencil-axis. This can be avoided by slipping a rubber band on to
the pencil in front of the discs, and another behind them. Leave just
enough space for them to revolve comfortably.
