It is transparent in itself, similar to ice. In order to approach high fidelity, this performance does not exclude that the surface of the solid desiccant is atomized with water, and then frozen instantly by ultra-cooling, so that a very thin layer of ice is formed on the surface of the desiccant, thus achieving the goal of being highly close to the ice. There was only a little coffee in the coffee pot during the performance. Why not fill a pot of coffee? This is very important. There are also some dialogues between Liu Qian and Dong Qing, which are also the key to this magic show. Please analyze the dialogue carefully. The content is: (Liu Qian and Dong Qing say: Please in the cup.

Pour some coffee, especially a little coffee! As a result, Dong Qing poured all the coffee in the pot into the cup. Liu Qian said! ! ! You fell? Dong Qing said it's okay, right? Liu Qian said it doesn't matter! These conversations are very important! Because the amount of coffee absorbed by desiccant is limited! Fortunately, Liu Qian is a magician and will be prepared. So Liu Qian put a little coffee in the pot from the beginning. But this is the highest limit for desiccant to absorb coffee! It takes a short time for coffee to pour into a cup and begin to melt the thin ice layer on the surface of solid dry ice. At this time, Liu Qian and Dong Qing said a few words after accurate calculation. When the song was finished, Liu Qian began to perform. At this time, the ice on the surface of the desiccant has melted, and the desiccant has begun to play a role in absorbing coffee for a long time. When the highly compressed desiccant absorbs a certain amount of coffee, it will quickly exert its absorption speed. So the last performance that the audience saw was continuous, and Liu Qian didn't stop. Because Liu Qian stops smoking, there will be less coffee. This solves the problem of coffee, so why does the straw have a black process of sucking coffee? This is easy to explain, because another magic shows a hand from the mirror, indicating that the mirror is specially made, so the straw passes through the mirror, and someone sucks coffee for Liu Qian on the other side of the mirror, so we can see the real phenomenon that the straw sucks coffee. Another explanation is that the straw is also specially made, the straw is double-layered, the outside of the straw is white and a little transparent, and the inside of the straw is a thick brown spring straw. Through the suction of Liu Qian, the brown spring straw in the straw will last for a long time, thus achieving the phenomenon that the straw sucks coffee.
