Props: One set of playing cards with all identical faces, a soap, a match box.
MAGIC:
Here is a trick for picnic parties. It is a real oldie, but dont let that put you off. We believe the motto 'old is gold'. Offer a set of playing cards to a spectator and ask him to choose a card. When he has done so, put the other cards away and ask him to burn his card to askes. Later, take the ashes into your right hand, and rub them on your left arm. Presto! The ashes will for a sentence... that is, the name of chosen card, "Queen of Hearts", which will be quite startling.
SECRET:
Before you start this trick, write the sentence, 'Queen of Hearts' on your left arm with toilet soap and let it dry. When you rub ashes on your arm during the show, the greasy soap will attract the ashes and the writing will appear.
As regards the selecting of the same card, of course, all the cards are Queen of Hearts in the pack. In case you find it difficult to collect Queen of Hearts, you can collect jokers.
