Instant and Easy Illusion for parlor, even for Stage show.
Magician shows an empty black jumbo box and a solid jumbo cube that has orange balls painted on it.
He places the jumbo cube into the black jumbo box.
With magical finger snap, the jumbo cube changes into a real live ball, a large-sized orange ball that matches the painted on the cube.
Now, he covers the lid on the box, so there is no opening. It is completely sealed.
With another magical finger snap, a solid, jumbo die cube appears from the empty box!
