Some card tricks, particularly ones which are based on maths rather than any real skill on the part of the magician, can be extremely impressive without A21 requiring a lot of practice. Here's a card trick that anyone can do. Take a normal pack of cards. Lay out three columns of seven cards and put the rest of the pack to one A22 side. You won't be using it for this trick. Now, ask a A23 member of the audience to pick one card without telling you which one it is. It might be a good idea to turn your back so they can show the card to everyone else.

Ask the person which column the card is in. Whichever column they A24 point to , you must pick up the cards column by column so that the column with their card in is in the middle of the pack. Don't shuffle the cards, but deal them out again into three columns. Be very careful how you do this, however. Don't deal them column by column. Deal the first row of each column, then the second row, etc. When you have the three columns laid out, ask the person to tell you which column their card is in now. Once again, A25 make sure , when you pick the cards up, that the column with their card in is the middle column you pick up. Go through the procedure one more time in exactly the same A26 way . Then, when you have picked up the cards for the third and final time, hold the pack so that the backs of the cards are A27 facing upwards. Slowly turn over the cards one by one. For each of the first ten cards you turn over, say one letter of the following phrase: 'This is your ...'. So, A28 for example, you'll say ‘T’ when you turn over the first card, 'H' when you turn over the second, and so on. For the eleventh card, say 'card!' as you turn it over. It will be the card they picked!
