It is REALLY cold at -20 degrees, and then add wind chill, we are cold. Our school was 2 hours late so we enjoyed a warm bowl of COCO Wheats and a science experience from Doughnut. We had heard that if we tossed boiling water into the air it would freeze before it hit the ground. It does freeze, steams a lot, and makes a cool sound. We had to do it twice and then dad said he had to come in it was cold outside.
