No. LXXIV.—THE CLIMBING HOOP
Paste or pin together the ends of a long strip of stiff paper so as to form a hoop, and place on the table a board resting at one end upon a book. Challenge those in your company to make the hoop run up the board without any impulse.
They must of course fail, but you can succeed by secretly fastening with beeswax a small stone or piece of metal inside the hoop, as is indicated in the diagram.

Invisible yet never out of sight,
I am indeed a centre of delight.
In quiet times I help to make things right,
Yet act as second in the fiercest fight.
