Cajas sincro

Tenyo has received special permission from creator Bob Ostin to release his close-up magic masterpiece with a newly-designed gimmick that we developed. The more times you repeat this trick, the more baffling it becomes. Our new gimmick is cleverly hidden inside the construction of the boxes, so there is no need to hide anything in your hands, or remove at the end of the trick. The secret is extremely well camouflaged. You'll be delightfully surprised at where we've hidden the gimmick. And your audiences will be astounded by this baffling magic.

Show two boxes to your audience, allowing them to see the inside of each. The boxes appear to be nothing more than an ordinary pair of empty boxes with sliding drawers. However... when you close the drawer of one box, the drawer from the other box mysteriously opens! To prove that there is no connection between the two boxes, you insert a playing card between them. The drawers still magically open and close as if by magic. For a surprising finish, the boxes are completely separated from each other, and they still move in sympathy with each other!
