Modern Art or Not

(Don't try this at home)

I preheated the oven to 400 degrees for the egg tarts yesterday. With my back turned to the oven I was carefully pressing the dough into the muffin pan. In the corner of my eye I noticed FIRE. Blue plastic was melting down and dripping onto the heat rod inside the oven. There was a huge flame much like one in a fireplace. I forgot to take out my large blue plastic salad bowl. I screamed FIRE and turned off the oven. My husband ran down with an extinguisher. Luckily the flames extinguished on their own. That's what I get for using my oven as a storage facility. Above is the picture of my contribution to modern art. I still need to clean the rest of the oven. How do I get the other pieces of blue plastic off the rack? Any ideas? Maybe I could turn the oven back on to melt the rest of the plastic off. After it dries it does form into hard plastic. I might give it a go but I'm a little scared something might go astray. As for my egg tarts I brought all the ingredients and baked them at my mom's house. We fanned out the house since it was toxic smelling.
