Royal magic manufactured several versions of this trick. These were a super early version.
The magician displays a small black tube and a ball, which sits squarely on top of the tube. It is clear that the ball will not fit inside the tube. That is, until the magician stares at the ball and begins to concentrate. With the power of his mind alone, the magician causes the ball to descend into the tube slowly, until it is completely inside the tube!
At the conclusion of the trick, the ball rises back to the top of the tube and both pieces can be handed out for examination.
An early Royal rack magic item that brings back memories. These are new old stock, so the instructions may show some wear, the props are mint.
