A classic pocket trick brought up to date.
The magician displays a small metal tube and a miniature ball, which sits squarely on top of the tube. Even in the hands of the spectator, it is clear that the ball will not fit inside the tube. That is, until the magician stares into 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.
This version of the venerable Ball & Tube trick has special design features which allow spectators to casually inspect the ball and tube while the gimmick is in place!
The ball adds a flair of the mysterious, and the improved design makes for more deceptive handling. No sleight of hand required.
