Coagulation powder has the characteristics of instant water absorption, which can make the liquid "coagulate" in a short time. Because there is little solidified powder, and it is white, close to the color of the bottom of the paper cup, so when explaining the paper cup to the audience, the audience will not find the secret. After the solidified powder in the paper cup absorbs the cola, the cola will solidify at the bottom of the cup. If you don't vibrate hard, even if the mouth of the cup inclines downward or even faces the ground, it won't fall out.
Magic demonstration: The magician began to perform the program. He took out a disposable paper cup and showed the audience the inside and outside of the paper cup, indicating that the paper cup was fine. Next, take out a can of coke, open it in front of the audience, and then slowly pour it into the paper cup. The magician put down the coke, tilted the mouth of the paper cup downward, even completely towards the ground, and the coke did not flow out. Where is the coke in the cup? The audience thought it was incredible. The magician pinched the paper cup in front of the audience and threw it into the dustbin.
