THE INVISIBLE INITIALS.
- Secretly select playing card from deck and place it on bottom.
- Letter the initials of the card on back of left hand with sharp-pointed piece of soap. For instance, the initials of the Jack of Spades would be J. S.
- Appear before audience, and ask someone to divide the deck of cards into two parts. Place a blank piece of paper on top of half which does not contain the selected card, and place other half of deck on top of paper. The selected card will then be above the paper.
- With your back turned, ask some person to write the initials of the card on the piece of paper, and burn it.
- Take ashes from burned paper and rub them on back of hand containing invisible soap initials. The ashes will stick to the soap, and the initials will mysteriously appear in trick "spirit writing."
