Coins go into the cup! There must be a mechanism under the tablecloth at the bottom of the cup!

There is no gap between the large cup and the small cup. The large cup is placed upside down, and the small cup is placed upright inside the large cup. There is also a big gap on the tabletop. The tablecloth is black to conceal the outlet switch action of the tablecloth ejecting coins from being noticed. The coin is shot from the table between the bottom of the small cup and the mouth of the large cup at the back of the small cup, which is blocked by the cup, and then bounces off the wall and bottom of the large cup twice before falling into the small cup. (The inside of the large cup has a large mouth and a small bottom, and the inner wall is obviously not perpendicular to the tabletop. Therefore, after the coin is shot vertically upward from the tabletop, it first bounces off the wall of the big cup and changes its trajectory. Then it bounces off the bottom of the big cup and just enters the small cup. The coin is shaking violently in the small cup, which shows that it is ejected very quickly) The mechanism for ejecting the coin can be triggered by Liu Qian's foot or a certain part of his body touching a switch on a certain part of the table, and the coin will be ejected from under the tablecloth. Came out.
