Card Counting
1. Get a full deck of cards, or to make it slightly easier take out the picture cards to begin with.
2. Ask a spectator to take the pack and look away. Ask them to take a card and hand you the remaining deck. They can shuffle it if they want to.
3. Now say you will look through the deck twice and then name the missing card.
4. As you go through the pack card by card add up all the cards modula 10 (that is when you get to 10 start again.) For example: Ace seven three five nine two you would add up as 1+7=8 8+3=11 modula 10 = 1 1+5=6 6+9=15 modula 10 =5 5+9=14 modula 10=4 4+2=7 and so on.
5. When you get to the end of the pack do the sum 10 - the number you have added up. This will give you the value of the card.
6. Now simply look through the pack again to find out which suit is missing.
Some guy will say they can do this card trick, it happens all the time. Hand him the pack and let him try, no one has ever managed it!
