Can exquisite gas cylinders really predict the weather?

Exquisite gas cylinders cannot predict the weather. Let me tell you what a "gas cylinder" is: gas cylinders are also called weather cylinders and wind aeration cylinders. It is said that one of them is meteorologist robert fitzroy, who is the captain of the Beagle which Darwin used to explore the world. He mixed distilled water, camphor, ethanol, potassium nitrate and ammonium chloride into a solution and sealed it in a glass bottle. As the weather changes, the crystallization of the solution in the bottle will also change differently. Observing the crystal can predict the weather.

According to the seller, as the weather changes, the crystallization of the solution in the bottle will also have different changes. Observing the crystal can predict the weather. For example, when the weather is clear, the liquid in the bottle is clean. When the sky is cloudy, the liquid will become cloudy and hazy. In cold or even snowy life, there will be large crystals in the bottle.

In order to verify the weather, we put the gas cylinder outdoors and let it stand. An hour later, we observed the change of the gas cylinder. From the first experiment, it seems that some gas cylinders bought online can sense the weather. In order to ensure the accuracy of the experiment, we boarded the top floor of the experimental building and conducted the second round of experiments.

The weather is fine, but the turbidity in the air bottle is still clearly visible at this time. Obviously, there is a big gap between the weather reflected by the bottle and the actual situation. From this point of view, it seems that gas cylinders cannot accurately perceive weather conditions.

In fact, this gas cylinder looks mysterious on this day, but it is not complicated to make. According to the online production strategy, the mysterious liquid in the bottle is mixed with camphor and alcohol to some extent. It seems that gas cylinders can only reflect the change of temperature to a certain extent, but can't really predict the change of weather. So from this perspective, the weather forecast bottle is more like an "appreciation bottle".
