An intriguing and challenging puzzle box at an affordable price!
Borrow a coin, bank note or a small item from someone and ask them to push it through the slot in the top of the money box for safe keeping.
Bet them if they can open the box in under 3 minutes they get to keep the item (it's funny because its theirs already).
After 3 minutes it is up you - offer to show them the secret or keep them guessing!
Plenty of fun for all the family!
