Jack was camping. He put a can of baked beans on his campfire, without opening the lid. The can exploded. What happened?

Too much steam expands within the can, causing it to explode

Beans contain water, and when water is heated, steam is created. As the steam increases, there's less and less room for it to go. The built up pressure causes the can to explode.
