My mother used to cook with one of these every great once in a while when I was a real little kid in the late 70's. I was always afraid of it because of the steam pressure sound it made while cooking with it. I always was afraid it would blow up or something. When she cooked with that pressure cooker, it was the only time I made it a point to avoid the kitchen.
