No one can open the Wonderfool Box but you as a magician can. Once you know the secret it is easy to open. Write a prediction on a piece of paper, put it in the box and let them try to open it. Or put a dollar in the box and tell them if they can open it, they can have the bill….if they can not, they must add another dollar to box through the small opening on it’s top. (age 7 +)
