It's not a reaction, it's what happens when you have a build up of pressure. In a carbonated drink like soda the carbon dioxide is dissolved in the water under pressure. If the pressure is released then you see bubbles. If the dissolve gas particles are given enough energy to become gas they can increase the pressure enough to blow a cork out.
Here's an analogy that might help:
Imagine you are on a plane. Every seat is taken and no more people can get on board. The plane is sealed up. The people are the dissolved gas particles. They stay in their seats and none can 'escape'. At the airport a door is opened and people start to get off. It's a controlled release and once outside they all wander off in different directions. Eventually the plane will empty - or the drink become flat.
If, however, at some point during the exiting someone blocks the end of the stairway, then you'll have some 'escaped' people, some people still in the plane (dissolved) and some on the steps, neither escaped or dissolved. These are the carbon dioxide particles that are stuck in the gas space above the drink in the bottle. The people on the stairs stop anyone else in the plane from getting out - so the drink is still fizzy.
If you give the people a really strong desire to leave the plane, like a fire alarm, then they will leave by any exit possible, like an emergency exit. If the only available exit is the blocked stairway then they'll rush at it and push past as hard as possible. Like our energised bubbles pushing past the cork.
The cork over the bottle's neck is going too be pushed by how much air is in the bottle.
Bottle is to cork - as jar is to LID.
It's a cork.
Cork for bottles is made from cork trees.
Carbon dioxide is produced from yeast. This carbon dioxide causes champagne to bubble and the cork to pop.
Because the air inside the bottle push out the wooden cork.
The cork
Champagne corks are shaped like that due to the extreme pressure in a champagne bottle...the shape helps ensure that the cork will not fly out under the carbonation.
The pressure build up is too much for the thin glass to handle.
A cork?
push in the cork and then tip the bottle upside-down to get the coin out
A CORK stopper is a plug for a bottle made of cork
