Before your friends arrive, hide twenty-four objects
about the room, putting each on something of the same color, so as to make them as inconspicuous as possible.
A
brass ring, stamp, drawing-pin, piece of black wool, rubber
ring, and so on are the most suitable for this.
Upon arrival,
your guests are given a list of the objects and a pencil, and
are asked to hunt round the room for the hidden things,
putting beside each name the place where they are eventually
found.
Twenty minutes is ample time to allow for this.
When the time is up, the answers are given, and one point
is allowed for each correct one.
