So when me and my girlfriend cook, a typical setup might look something like a pan on one heater and a pot with something on the other. Today I was cooking eggs and she was boiling water. Something was in her water (didn't look like eggs at all) and she said it was the eggs from my pan, jumping into her pot (assuming due to pressure). What exactly happens when eggs, bacon and other things "blow up" on the pan? I'm guessing it's built up pressure in the fluids which then makes them pop. Obviously with bacon, you can feel these fluids on your hand if you're close but what is this fluid? Is it water? Grease? Is it dangerous? Does she have any reasons to remove her pot until I am done cooking my eggs (or whatever I am cooking).
