RING AND RIBBON

Select two pieces of ribbon, alike in length, breadth, and color;
double each separately, so that the ends meet; then tie them together
neatly, with a bit of silk of their own color, by the middle, or
crease made in doubling them. This must all be done in advance. When
you are going to exhibit this trick, pass some rings on the doubled
ribbons, and give the two ends of one ribbon to one person to hold,
and the two ends of the other to another. Do not let them pull hard,
or the silk will break, and your trick be discovered by the rings
falling on the ground on account of the separation of the ribbons.
Request the two persons to approach each other, and take one end from
each of them, and without their perceiving it, return to each of them
the end which the other had previously held. By now giving the rings,
which appeared strung on the ribbon, a slight pull, you may break the
silk, and they will fall into your hand.

THE CHANGING BALL TRICK

Take a ball in each hand, and stretch your hands as far as you can,
one from the other; then state that you will contrive to make both the
balls come into either hand, without bringing the hands near each
other. If any one dispute your power of doing this, you have no more
to do than to lay one ball down upon the table, turn yourself, and
take it up with your other hand. Thus both the balls will be in one of
your hands, without their approaching each other.
