Picture this. It's around 7 o'clock on a Sunday night. Dad's at a meeting. Younger brother lays on the couch, engrossed in his book- the radio is on. In the kitchen adjoining the living room the mother and older daughter have just finished cutting up tortillas for some homemade chips- they're on a baking tray ready to go in the oven. While waiting as the oven heats up the daughter goes to a nearby closet to search for a paper bag to put the gifts for her teachers in. Suddenly there is a loud sound. "BZZZZZZT!" Uh-oh...it came from the oven. The mother opens the oven door and smoke streams out. What just happened? Did the element blow? A faintly electrical/chemical smell fills the air.
So yeah. Dunno what just happened but that's the story.
