However, opening the cans was quite a challenge - soldiers worked with stones and bayonets and it was only 30 years later that someone designed the first can opener! Although cans travel much easier across a battlefield, for decades they would not only mysteriously explode, but would also cause the harshest diseases. But how could the scientists of those days know? It...
