Popcorn is made from small, hard, dried kernels of corn which, when heated, explode and invert. The lid should be kept firmly on, or the corn would pop all over the room. This is a popular treat at the cinema though I must say that, when I hear talk of the explosion of obesity currently a topic of horror, I glance at the bucket loads of popcorn people munch their way through as they sigh over "The English Patient" and think that might be the answer.
