Jumping Elastic

Effect: An elastic band penetrates the fingers.
Secret: Place an elastic band over the first two fingers of your left hand as shown. With the right hand stretch the band to show it really is over the fingers. Close the left hand, at the same time secretly allowing the tips of all your left fingers to go into the band as shown in the second drawing. Open your hand and the elastic band will jump from the first two fingers to the third and fourth fingers. Keep the back of your left hand towards your audience at all times when performing this trick and it will look like the band penetrates through the first two fingers
