Can someone help explain how a closed soda can rupture from a pin hole?

1 Answer

Answer :

How does it happen? The pressure inside the can is much higher than the pressure outside the can, and the aluminum isn’t strong enough to handle it. If someone had punctured the can with a pin then it would have leaked right away. Likely, the cans were a little old and maybe had a defect or dent in the metal from handling. When the pressure rose, it broke at that weak point.
