Burning down the house

[Chemical]

i came home from school one day to find an extremely foul odor as well as some blackened egg shell on my ceiling, walls and well anywhere in a 7 foot radius of the pot I left the poor thing to boil in.

How did that happen? Whenever I forgot that I boiled eggs they just sit at the bottom of the pot, overcooked, with a hot-as-hell pot still slowly melting.

I'm not sure really.
The pot was fine but the egg was blackened and had exploded into tiny fragments.
This was in the old apt.
I had to actually throw away that pot.
