Why does a chopstick bubble when placed in a beer bottle?

When a chopstick is inserted into a beer bottle, the bubble will come out, which can be explained by the following steps:

1. When we insert chopsticks into a beer bottle, a small bubble will form around the chopsticks.

These bubbles are due to the release of carbon dioxide in beer. Beer contains a lot of carbon dioxide in the form of small bubbles.

When we insert chopsticks into a beer bottle, a small bubble will form around the chopsticks, and these bubbles will gradually become bigger.

When the bubbles become large enough, they will float to the surface of beer and then burst.

This process will release carbon dioxide gas, thus forming the effect of bubbles coming out.

So when a chopstick is inserted into a beer bottle, bubbles will appear. This is because the carbon dioxide in beer is released, forming small bubbles, which gradually become larger, float to the surface of beer, and then burst, releasing carbon dioxide gas.
