Fire in the hole!

The kids have mastered a new talent, they learned how to use the....Microwave! I couldn't be more happy, now instead of Mom I'm hungry, it's Mom can I heat up a pizza? does it get better than that? It was great until yesterday, Liesel asked if she to could learn this new and great thing and I said o.k. but before you press start have Allie or Mommy check it. She was successful, and it might have gone to her head just a wee bit because then unknown to anyone but Liesel, Max asked her to make him a pizza and she did it without it being checked. I was sitting in another room and smelled something strange but thought it was coming from outside, then Liesel comes up and says "Mom, I made a mistake making a pizza" I come into the kitchen to find the Microwave billowing smoke and reading it has 10 minutes left to cook the is a very black pizza like flat coal which I rush outside. But now my entire house smells of burning smoke, my new, did I mention it was new?, microwave is toast and I now know my fire alarms don't work because not one went off. So if anyone has any great tips for fumigating my house it would be GREATLY appreciated.
