Take the loop and pass it down through one of the corner holes under the thread, and pull the bead down through the loop. Do this to each corner, and the loop will now be seen to surround the whole of the threads: pass the loop down over the cardboard, when the ring will come off. To replace the ring reverse the movement.

(2) The Card Bridge.—Take a visiting-card and bend it as in [Fig. 2], so that the parts bent up are half an inch high. Now place this card on a table, resting on the two bent parts. The puzzle is to blow the card bridge right over on to its back. This will not be so easy a job as it appears. The secret is in blowing on the table about six inches in front of the bridge.
(3) The Triangle Puzzle.—Take six pieces of stick about three inches long, and with them form four equilateral triangles, each triangle to have one stick for the side. This is done by placing three sticks in a triangle on the table, and placing a stick at each corner and letting these three sticks come together at the other ends.
