Criss angel? There is a magic knife on the finger prop. Finger prop is a kind of finger sleeve, flesh-colored, similar to a real finger. It's hard to see when you wear it on your hand. There is a blade between your fingers, which is very sharp. Scratch the plastic bottle and it will open if you are not careful. When you enter the mobile phone, you should face the audience sideways, and when you take the bottle, you should cut your palm. The biggest drawback of this magic trick is that it can't be tested for the audience after the performance, and the exhibition time can't be too long.
