When temperatures rise or altitude increases, the balance of pressure inside an aluminum beverage can changes.
Hotter temperatures increase internal CO₂ pressure, while higher altitudes lower the external pressure around the can — both increasing the pressure on the dome.
That’s why beverage cans are engineered with a concave base: to resist these shifting forces and prevent “dome reversal,” when the bottom pops outward under pressure.
