Decoding Liu Qian drinking coffee in the mirror

Then there is the magic of drinking coffee in front of the mirror. First of all, Liu Qian can't really drink coffee. Some students may ask, but I clearly saw him drinking. Children's shoes, did Liu Qian really spit out coffee from his mouth? We only saw his straw change from transparent to brown, and then Liu Tongxue pretended to enjoy it, making us think that he really drank coffee. The fact is that his straw was tampered with beforehand. Please look at the picture below.

Why is this flexible port not brown? This proves that Liu Qian didn't really drink coffee. Some students may ask again, what about the coffee in the quilt? Come on, let's look at the next picture.

When we know that Liu Qian didn't really drink coffee, there is only one possibility for coffee-it was absorbed by some substance. There are two suspicious things in this magic: ice cubes and coasters. You know, any props used in magic will never be just decorations, and every prop has its magical function. Look at the picture carefully. Let's look for the flaws in the cup. Did you find it, dear? Let me tell you something.

Don't believe it? Look at the picture below.
