How to make your own weather forecast bottle

By preparing a test tube bottle and some chemical reagents in advance, you can make a small tool that predicts the weather.

What I share with you here is a very simple way to make a weather forecast bottle. Please follow along and make it.

Prepare some materials in advance, natural mothballs, ammonium chloride, potassium nitrate, ethanol and distilled water.

First weigh some natural camphor and measure out some alcohol.

Weigh some potassium nitrate and ammonium chloride, and add the two prepared things to water.

After dissolving, add some alcohol to dissolve it into the camphor.

Shake it quickly and The precipitated matter is subjected to a second solvothermal process

If there is still some undissolved below, then heat it some so that all the solvotherms can be absorbed.

Transfer to a bottle prepared in advance.

Here I would like to share with you the principle of the experiment, which mainly involves static electricity and glass channels, as well as the numerical difference between the weak air pressure between the bottle and the outside of the bottle. It will also have an impact.

According to the above conditions, it can affect the solubility of some substances. When it rains, snowflake-shaped precipitation will appear.
