The magician shows a small ball and a small transparent box that is securely closed with two elastic bands. He places the box on the table, puts the ball on top, and covers everything with a silk. Now something magical and strange happens, as the audience will see the ball penetrate the lid of the closed box.

The silk is immediately removed to show that the ball is now truly inside the closed box!
The silk is not included.
The box measures 4 x 3.5 cm (1.57 x 1.37 in.)
