Looking for the name of a kind of cup. It’s the kind of cup that makes cold water hot when shaken and hot water cools down when shaken.

55 degree cup.

The 55-degree cup is a water cup with rapid temperature change. It is the first high-tech product with a utility model patent independently developed, designed and produced by Beijing 55-degree Technology Co., Ltd.

Introduction to the working principle of the 55-degree cup:

1. First of all, there must be some kind of substance in the cup. The water is set at 55 degrees. When we pour 100-degree boiling water, the wall of the cup begins to absorb heat (ice melts into water) until the temperature inside the cup drops to 55 degrees, and the side heat absorption is completed.

2. If we don’t drink it, put it aside. When the temperature of the water slowly drops below 55 degrees, the wall of the cup begins to slowly release the heat it has just absorbed, thereby achieving the function of heat preservation and always keeping it warm. The temperature stayed at 55 degrees.

3. So, how does the cold water heat up to 55 degrees? When we drink the hot water, as mentioned before, the heat of the 100-degree hot water is absorbed by the wall of the cup. When we pour in cold water, the wall of the cup begins to instantly release heat material and the water turns into ice again, so that the cold water in the cup quickly Warm up to 55 degrees.

4. In this cycle, when we enter boiling water again, the wall of the cup begins to absorb heat again and the material ice turns into water, which can cool down again. In other words, when we use a cup of boiling water, a cup of cold water, a cup of boiling water, and a cup of cold water, the temperature can reach 55 degrees every time.

5. If we pour boiling water and finish drinking it, can it immediately become 55 degrees if we continue to pour boiling water? The answer is no, because the heat of the boiling water we just poured in is absorbed by the wall of the cup. It has been absorbed and has not been released, so if you pour boiling water again, the cup wall cannot absorb the heat, so you have to wait for half an hour before using it. Of course, we can also pour it with cold tap water to let the heat from the cup wall release. Pour in the boiling water again.

6. If we have not poured boiling water before, and the wall of the cup has not absorbed heat, but directly poured cold water, can it be heated to 55 degrees? The answer should be impossible.
