The Black Hole The magician shows a card with a hole in the middle to the audience. Next, the magician inserts a pen or finger from behind the hole to prove that the hole is real. Then, when the magician blows on the card, the hole disappears, and a black circle appears! Furthermore, when the magician rubs the black circle with a finger, the black circle vanishes! This trick is easy to perform and leaves a strong impression on the audience! Contents: Special gimmick card, Japanese instruction manual
