Weather forecast bottle why the thinner the pipe, the easier it is to see the weather disease.
Because the thinner the pipe, the more obvious the liquid level change inside. Weather forecast bottle, also known as storm bottle, is a kind of equipment used to predict weather changes. Its working principle is based on the influence of temperature change on the chemicals in the bottle. In a closed glass container, there is a transparent solution composed of several chemicals. When the outside temperature changes, the chemicals in the bottle will change, and different crystals will be precipitated, thus showing various shapes to represent the weather changes. Due to the principle of thermal expansion and contraction, the thinner the pipeline, the more obvious the change of liquid level inside it, and it is easier to observe the change of weather pressure and predict the future weather.
