Soda cans can potentially explode in the fridge due to a phenomenon known as "can rupture" or "can failure." There are a few reasons why this might occur:
Temperature changes: When a can of soda is exposed to extreme temperature changes, such as being placed in a very cold environment like a fridge or freezer, the liquid inside can expand and create pressure. If the pressure becomes too high, it can cause the can to rupture or explode.
Carbonation and pressure: Soda contains carbon dioxide gas, which is responsible for creating the fizzy bubbles. When a can of soda is sealed, the carbon dioxide remains dissolved in the liquid under pressure. If the pressure inside the can increases significantly, either due to temperature changes or other factors, it can exceed the can's structural integrity, leading to an explosion.
Physical damage: If a soda can has been physically damaged, such as being dented or punctured, it can weaken the can's structure and make it more prone to rupture. Even a small dent or imperfection can increase the risk of an explosion.
To minimize the risk of soda cans exploding in the fridge, it's recommended to store them at a stable temperature and avoid subjecting them to rapid temperature changes. Additionally, handle cans with care and avoid damaging them. If you're concerned about a can's stability, it's best to dispose of it to avoid any potential accidents.
