Our BEAUTIFUL WOOD COIN PRISON is a new item based on an ancient puzzle.
Sit this mystery on your desk for a great conversation piece. Small items are placed in but can not come out! Unless you know the clever secret!
We supply a beautifully polished round wood container large enough to hold a borrowed coin, with a hole in the bottom which lets you look into the box and see what's inside.
Remove the stopper lid and ask a spectator to place a coin into the box.
Place the lid back on and hand to your spectator, asking him to remove his coin and return the box to you.
Imagine his surprise when he is unable to open the box!! The SAME BOX he has seen you open and close right in front of his eyes!
The stopper revolves freely on the box, but cannot be removed, unless you are in on the clever secret. The box will hold large coins or any similar sized objects. Your spectator's coin can be marked by him and then placed into the box. And YES - you can remove the spectator's item and return it to him!
This precision wood box is superbly constructed and a very desirable prop complete with an ideas sheet. It works on a really clever principle, and will withstand the closest examination!
Carry it with you and do it anytime without any prep!
Can be used as a paperweight
Use the hole in the stopper lid as a pen stand
Beautifully made wooden box is 2.25" square and approximately 2" high
(Also check out our Brass coin prison which works on a different principle).
