Cut a slit close to one edge lengthwise of half a playing card, and of
the other piece make a cutting in the following shape:—
[Illustration: Fig. 97.]
Pass the thin long ends through a button, a perforated disc of paper, or
a piece of pipe-stem, after having taken the slip of card in its loop,
and unfold the large square wings.
If the bands are not shown, the way to get the little cylinder off is
truly undiscoverable.
[Illustration: Fig. 98.]
It is done, of course, by doubling the flat card till the slip can be
pulled through the pipe-stem, when one of the square wings will go
through it, and the release follows naturally.
