Exploded?!?!
Exploded?!?
Right. Mug+Water. Egg broke into it. Microwaved. It exploded hah, like.. to the point where the microwave door came open too.
WHY?!
Answers:
You forgot to break the egg yolk and the sac surrounding it collected steam as the egg cooked. So much steam that it got bigger and bigger and then KABOOM!!
It was a terrorist egg.
Probably trapped steam in the yoke.
well the other chick was close, it actually has to do with the microwave. If you didn't know already a microwave cooks from the center outwards, making the most "heat pressure" at the center of whatever it is that you are cooking. So, naturally the eggshell couldnt handle the expanding egg.. try it again with just the yolk and see how fast a microwave cooks egg.. you literally scrambled the egg inside the shell. I wasn't the steam, it was the egg inside itself that exploded. next time just stick to the burner and a pan. :)
The simple answer is compression.
A "contained" explosion is more energetic than one "in the open" as air is far less dense than any liquid ... if you opened a firecracker and poured out the contents and lit it, it would burn - quickly - but would not have the same force as if you lit the firecracker when the 'fuel' is contained and compressed inside the casing. Water can act like the firecracker casing.
Yes, the yolk built up steam, but the force was "held" by the water/mug combo. The water magnified the final burst of the yolk and, I'd expect, broke the mug as well, helping to damage the microwave door.
Are you familiar with the TV show "Mythbusters"?
There was an episode where they tested methods of cracking a safe - one with a glass-panel relocker. This employed a small quantity of explosive, lowered into a hole drilled in the top of a safe after the safe had been filled with water - through the drilled hole.
The small amount of explosive alone - no water - would have only broken the glass panel inside, immediately rendering the safe impenetrable. But when the safe (which was at least a 5'-6' tall cabinet), but when the safe was sealed, filled with water, the explosive lowered into it and detonated, the additional compression and "containment" by the water and safe combined to blow the door off the safe - sent it some 30 yards away - and bow out the reinforced walls.
Something similar happened to you, just on a smaller scale.
