SOl. A MATCH TRICK

You must secrete the match inside

in the manner shown by the dotted

lines in the illustration, so that the

head is just over the edge of the tray

of the box. In closing the box you

press this extra match forward with

the thumbnail (which, if done care-

fully, will not be noticed), and it falls

into its place. Of course, one of the

matches first shown does not tum

round, as that would be an impossi-

bility, but nobody ever counts the

matches.

562. THREE TIMES THE SIZE

The illustration shows how two en-
closures may be formed with 13 and
7 matches respectively, so that one
area shall be exactly three times as
large as the other. The dotted lines
will show that one figure contains two
squares and an equilateral triangle,
and the other six squares and three
such triangles. The 12 horizontal and
vertical matches have not been moved.

563. A SIX-SIDED FIGURE

The illustration shows the simple

answer. We did not ask for a plane

figure, nor for the figure to be formed

with the 9 matches. We show (in per-

spective) a cube (a regular six-sided

figure).
