A card trick that integrates Black Hole and Matrix so perfectly! The black holes in the four corners jump four times in succession. This is a very practical and visual magic trick. A playing card with four holes in the four corners (provide the hole puncher by yourself). No need any shielding. The four holes are gathered together one by one. When you think the magic is over, the four holes instantly separate and return to their original positions. All this looks so clean, pure and incredible. Easy to use and master, even without watching the teaching video. Take it and enjoy the incredible effect-it will blow you away!
