Excuse me, is the cylinder just finished like this?

Mix distilled water, camphor, ethanol, potassium nitrate and ammonium chloride into a solution and seal it in a glass bottle. As the weather changes, the crystallization of the solution in the bottle will also change differently. Observing crystals can predict the weather.

Then there are the introductions of various Taobao sellers, all of whom say that they can predict the weather-"When the liquid in the bottle is clear and clean, it means the weather is fine; When the liquid in the bottle is turbid and hazy, it means that the sky is gloomy; When a large crystal appears in the bottle, it means that it will cool down or even snow. "

Conclusion: Let the gas cylinder become a quiet beauty prop!

According to the above series of discussions, I believe everyone can see that the weather forecast bottle-

First, the weather is definitely unpredictable;

Second, not only can not forecast, but also can not reflect the weather in real time;

Third, it can not only reflect the natural weather, but also accurately reflect the indoor temperature.

So, let's just say that the weather forecast bottle is actually a handicraft that can roughly reflect the general change of indoor temperature.

As far as function is concerned, it is not as good as a simple thermometer.

Of course, it can be used to observe crystal changes, and it also has aesthetic effects, that's all. As for other incredible function propaganda, I can only say-impossible!
