A ball continually appears and disappears, mysteriously passing from the magician's pocket into the chop cup. In the end, the ball turns into a bigger ball, or into a fruit, or into something else.
In addition to the instructions, the plastic cup and two "crochet balls" are provided. The bowl is 6.5 cm high and has a diameter of 5 cm. The balls have a diameter of approximately 2.3 cm.
