Three examined wooden blocks, two red and one yellow are placed inside an open cabin made of wood, with the yellow block between the red ones. The two red blocks are squeezed together and the yellow block gets smaller and smaller until it vanishes completely! In the end the two red blocks can be given out for examination, again.
A great close-up illusion, very well made.
The gimmick is even more beautiful than the effect itself. It'll drive you crazy. Entirely made in teak wood.
