What about drinking coke with salt?
Adding salt to cola will produce many bubbles for the following reasons:

1, the main component of cola is carbonic acid, and the component of salt is sodium chloride. After entering water, some hydrogen ions can be separated out after dissolution, and they react chemically to produce carbon dioxide gas;

2. After adding salt to cola, the solution concentration increases, and the solubility of carbon dioxide decreases, thus overflowing in large quantities;

3. A large amount of carbon dioxide gas is dissolved in cola, which will slowly release carbon dioxide without external interference. When a small amount of finely divided solid powder, such as salt, is added, and a small amount of gas is adsorbed on the surface of finely divided powder, many gasification centers will be generated in cola, which will speed up the release of carbon dioxide in cola.
