Rub your hands together hard and they get warm: a meteor hits the air at tens of kilometres every second, far faster than a bullet, and the air in front of it is squashed so hard it glows.

Who acts: you, hands, meteor, air · What happens: rub, get, hit, squash, glow · To what, where: hands, air, tens
