You can shake the form, so that a large amount of carbon dioxide in the beer bottle to dissolve and mix, and then open the beer bottle cap, plug the bottle with your thumb, the semi-open state can make the bottle under the large pressure impact, the beer is sprayed out. This is mainly caused by the use of strong pressure, after the mixture of gas and liquid, the rise of gas drives the rise of liquid and forms a large number of bubbles.
Beer belongs to the fermentation, which contains a lot of carbon dioxide, after the beer is opened, the beer bottle is forcibly shaken, and the beer is sprayed, which makes the pressure in the bottle decrease, the carbon dioxide solubility in the bottle decreases, resulting in the escape of the gas in the beer bottle.
A quick shake before opening the lid will give the gas a higher spray, which will allow the beer to burst out
