This tabletop illusion is always a big hit with audiences!
A red, a yellow and a green ball are placed into a narrow tube. Instantly, the balls change places. As a climax, the yellow and green balls are put into the tube, but the red ball is put into a small box. Instantly the box is opened- the red ball has vanished from the box and has reappeared in the tube with the other two balls!
Very easy to perform and gets a great reaction every time!
