Context: I take the case of soda to the sink for examination . All 12 cans of soda were only partially filled with liquid . Some contained as little as 25 % soda ! All the extra air seems to have oxidized the can from the inside , and after some time the can could no longer withstand the pressure and it would pop it 's top . Three other cans had already burst , but not in a location that would cause any spillage .

Answer:

It may have been a manufacturing error that there was not enough of the beverage in the can .



What may have been the reason there was very little liquid in the cans ?
