It's best to print on card stock if available. Carefully cut into six cards so that 32, 16, 8, 4, 2, and 1 appear in the top left corner of each card respectively.
How they work: Ask someone to choose a number between 1 and 60. Hand them the cards and ask them to pick out all the cards that contain their number.
Now you have two ways to "Magically" reveal their number: take the cards with their number and add the number that appears in the top left corner of each or their cards to reveal their number, OR ask them to add numbers you tell them. Give them the number from the top left corner of each the cards that does not contain their number. Tell them to add those numbers together subtract that number from 63 to reveal the number they chose.
