Today, my wife added water to the kettle on top of the stove while I was cutting down the air. I usually add hot water but she added cold. The kettle was dry and I had around 675° on the stovetop. I stood up and closed the lid on the kettle for her, and about two or three seconds later water and steam shot out of the spout like a volcano and scared the chit out of me! I jumped back and it got the leg of my pants and the stovetop and floor. Never saw anything like that before. I'm sure we did something wrong.
