Effect:
You bring out a set of dominos or borrow it from a friend. After asking a series of questions, you carefully select a single domino and set it aside. You ask a spectator to take the rest of the dominos and arrange them in traditional domino fashion with like numbers touching each other and to lay the dominoes into a large circle.
When the spectator is done laying out the dominos, there’s one domino that’s needed to close the circle. It turns out that the domino that you set aside earlier is the exact domino needed to close it.
Materials:
A complete set of dominos
Preparation:
None
