some more cards, then you randomly dealt out some more cards, then you mixed them up a bit, and if you did the trick correctly then you found the "twins" of my cards. turn over the top card in each stack and see if you did the trick right!"
this is an old classic which works every time! can you figure out why? first put the deck of cards face-down on the table, then cut the deck by picking up the top part of the deck (make sure that you only pick up less than half of the deck) and putting it face-down on the table next to the bottom part
