What makes a soda explode?

When a bottle of soda is shaken and opened, the dissolved carbon dioxide gas rapidly escapes from the liquid, forming bubbles and causing the soda to fizz. The pressure inside the bottle increases as more gas is released, and if the pressure becomes too high, the bottle may explode. This can happen when the bottle is shaken too vigorously or if it is left in a hot environment, such as a car on a hot day.

The temperature of the soda also plays a role in how likely it is to explode. Warmer soda contains more dissolved gas, so it is more likely to erupt when shaken or opened. Colder soda is less likely to explode, but it can still happen if the bottle is shaken too vigorously.

Another factor that can affect whether a soda bottle will explode is the amount of remaining bubbles of dissolved gas on the sides of the bottle.
