FIRE!

So on Tuesdays I babysit my nephew Greyden and he is just at the age where he likes to play with pots, pans, measuring cups, all the fun stuff in the kitchen. So I had Will and Kyanna get all that stuff out and play with him. It was so cute all three of them were in there banging stuff around (well mostly just Greyden) and Will and Kyanna were pretending to bake a cake. I really wish that I had taken a picture. Anyways I remember thinking I need to check in the oven before I start dinner tonight. Well.... I forgot (I'll blame pregnancy). So I preheated my oven and went back in the living room. Then my friend Jill called so I went into the kitchen to answer the phone and just as I said hello, I looked over at my oven and flames were seriously coming out of the oven! All I could do was yell into the phone "my oven is on fire, my oven is on fire!" So I hung up and luckily I had a vase full of water right there and I just poured it into the oven. I am not sure if that was the smart thing to do, but it worked. The fire alarm was going off, my kids were freaking out, and it was very very smoky and stinky! I discovered that it was a piece of Tupperware. So now I have melted Tupperware all over the inside of my oven. Any suggestions on how to clean it?
