Volcano Water
Really weird thing happened. I was boiling a pot of water. Just as it started to boil, a friend called, so I turned off the stove. After ten or 15 minutes, I figured I'd better continue making dinner even though I was on the phone, so I turned it back on again. It boiled very quickly, but kinda weird, like a really furious boil, with water jumping all over the place, not just bubbling. All of a sudden, a huge bubble of water burst out from the middle of the water, like it was exploding up and out of the pot. Water was all over the stove and floor. Very dangerous. My theory is that the water in the "middle" was already hot, even though the water on the surface was cooling. So when I turned on the stove, the water in the middle got super-hot and it exploded. But I need to look this up and find out what really happened. Could be an interesting science research project. But kind of dangerous.
