What makes a can of biscuits pop?

A can of biscuits popping is usually caused by pressure buildup inside the can. Here's why:

* Moisture: The biscuits themselves contain some moisture, and the air inside the can also holds humidity. This moisture can turn to steam when heated, increasing pressure.

* Baking Process: Biscuits often undergo a baking process that creates steam and gases within the can, which get trapped and build pressure.

* Temperature Changes: Changes in temperature, like when the can is exposed to sunlight or heat, can cause the gases inside to expand, leading to pressure buildup.

* Damaged Can: If the can is damaged, dented, or has a weak seal, it might not be able to contain the pressure, resulting in a pop.

Here's what can happen when the pressure builds:

* Pop: The pressure can eventually overcome the can's strength, causing it to burst open with a loud pop.

* Bulging: The pressure might not be strong enough to pop the can but can cause it to bulge or become deformed.

Tips to prevent popping:

* Store in a cool, dry place: Keep the can away from direct sunlight or heat sources.

* Don't expose to extreme temperatures: Sudden temperature changes can increase pressure.

* Check for damage: Make sure the can is not dented or damaged before storing it.

It's important to note that while a popping can might seem harmless, it can be a sign of spoilage. If you hear a can pop, it's best to discard the biscuits as they may no longer be safe to consume.
