Smoke without Fire

Well, ok, it was without fire, but I replaced the fire with some nasty microwaves.
There I was, nuking a bun in the oven. Everything was going great, and them BAM, from one second to the other, the entire microwave was filled with smoke, and so was a better part of the kitchen.
It's interesting to see how that can happen so quickly, and without warning.
It's a bit hard to breathe in the kitchen right now, but I have both doors open and a fan going, so I might be able to get a sandwich just before I leave for school.
If not, then it's hungry class day for me.
Atleast I got my tea out in time.
