Fig. 5.—Instantaneous knots.
Bring the first and second fingers (1 and 2, [Fig. 5]) over C, catching hold of the end, A, behind the wrist. This will be easy after a few attempts, but you must be careful to see that the end A is of fair length, otherwise the trick will be impossible.
Now bring the end A up through the resulting loop by means of the two fingers. The consequence will be a knot in the end of the handkerchief. Your left hand has, meanwhile, been doing the same thing and with equal rapidity, so that it will appear to the spectators that, by a sudden flash of the hands, you have formed two tight knots, one at each end of the silk.
A Flick Knot
Hold the handkerchief stretched between your two hands in the manner shown in [Fig. 6]—that is, inside the first and second, and outside the third and fourth fingers of each hand.
Fig. 6.—A flick knot.
Give the left hand a half turn, as in [Fig. 7], thus enabling the first and second fingers of the right hand to grip the end A, whilst at the same moment the thumb and third finger of your left hand catch hold of the end B.
