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 .

Question: What may have been the reason there was very little liquid in the cans ?
Answer: Someone popped the top on the cans and poured it out so only 25 % of the soda was still in the can .None of the above choices .It may have been a manufacturing error that there was not enough of the beverage in the can .Someone shook the cans really hard so the can burst and the soda came out all over the place .
