With the small ball you now execute the pass as described under Example 4 on p. 96. Then actually place the ball in the mouth, pretend to swallow it, and produce the one from the vest pocket, which will appear to be the same.
You now seem to place the ball in the left hand, really palming it; then bring the left hand down with apparent force on the top of the head, showing the ball between the teeth. Here raise the right hand as if to take the ball from the mouth, but really push it back and show the palmed one. Then repeat the same pass, but this time actually let the ball fall from the mouth into the left hand, the right disposing of the palmed ball into the profonde.
I have seen a series of passes, including the above, performed with two eggs in place of the small balls, but unless the performer be endowed with a colossal cavity between the upper and lower jaws, I should not advise him to attempt this.
THE HANDKERCHIEF BALL.--This forms a very good introduction to a billiard ball trick, all that is required being a ball of the usual size, hollowed out so as to take a handkerchief, with an opening one inch in diameter on the surface. This ball is suspended behind the top rail of a chair by means of a pin.
After performing any trick in which a handkerchief has been employed, carelessly throw it over the back of the chair while you roll up your sleeves. If you do not care to roll up the sleeves, perform any small trick before proceeding with the present one, otherwise it might be too palpable that the handkerchief was thrown over the chair for a purpose. Then take up the handkerchief (secretly securing the ball) and gradually work it into the ball, being careful to keep the ball out of sight as much as possible until the handkerchief has totally disappeared. Finally throw the ball into the air, which can safely be done providing it and the handkerchief are both of the same color, which would not admit of the hole being observed.
At this point, should you desire to proceed with a billiard ball trick, you can do so by changing the hollow ball for a solid one in the same manner that you changed the solid ball for the trick one in the "Multiplying Billiard Balls."
THE DISSOLVING BILLIARD BALL.--This forms an excellent conclusion to a billiard ball trick. A glass tumbler three parts filled with water is given to a gentleman to hold. A ball is then covered with a handkerchief and given to the gentleman with a request that he will hold it over the glass and at the word "three" will allow it to fall into the water. This is done, and upon the handkerchief being removed from the tumbler, nothing remains but the fluid, which is perfectly transparent, the ball having apparently been dissolved therein.
