My friend did this magic trick where she had 3 rows of ten cards. I picked a card and told her what row it was in. She did that three times (where she grabbed all the cards and put them in three rows of ten and I told her which row they were in) then she put the cards in four piles of four, and I picked two piles, and she got rid of them, then I picked another pile and got rid of them until I was left with one pile(only four cards left) I picked two cards, and she threw them out then I picked one card and she threw that out. The remaining card was mine. How did she do that??
