The performer displays three solid blocks in a see through "cabin" resting on a stand. The blocks are removed from the cabin, and can be examined, they are all solid blocks, - no shelves, trap doors, or other gimmicks. The blocks are replaced in the cabin, with the yellow block between the two red ones. The two red blocks at the ends are now squeezed. Visibly the yellow block is seen to get narrower and narrower, till it completely vanishes. It has been visibly squeezed into thin air. Finally the two red blocks are removed from the cabin, which is otherwise empty. The two red blocks may be passed out for examination if you wish, - they are just solid wooden blocks.
