In this easy trick, a coin is placed into a handkerchief where it mysteriously disappears. You can perform this one just about anytime or anywhere. All you need is a quarter, a handkerchief, and that special secret. (Spoiler: The secret is a rubber band.) The goal of the game is to get all three cups in a line with the mouth up. Each player gets three consecutive turns to do this. A player can move two cups at a time with each turn. Your turn is first. Set your three cups in a line, with the first face-down, the second face-up, and the third face-down.
First turn: Turn over the first cup and turn over the second cup.Second turn: Then turn over the first cup and the third cup.Third turn: Finally turn over the first cup and the second cup.
You should now have all cups in a line with the mouths up. Now, it’s the other person’s turn; however, you will set up the cups so the first and third cups are face-up and the second cup is face-down. This renders it impossible to get all of the cups facing up in three turns as you did the first time around.
