EFFECT: From an idea by Thurman Smith of Dayton, Ohio. A small box is shown empty. Later, when the box is opened, it is found to contain a block, a die or anything else that will fit in the box. (This is a great utility item for the reappearance of the block from the "SEE THRU BLOCK BOX".)Suggested venue: Stage/Platform
