Our Teacher was telling us a story when he was in school. And it was their cooking final and they had to make a dozen of cookies in one hour. So for 45 minutes of the final they were throwing cookie dough all over the walls then they realized they were in trouble and didn't have enough time to bake the cookies. So they fired up the oven to 800 degrees and baked it for 5 minutes. And the oven blow up snd you could see the lights flickering on and off also the school shorted out.
