Napalm and Silly Putty

RUNNING HOT AND COLD

The refrigerator butter warmer is a strange invention. Originally, humans were cold so they built a warm enclosure. A house. Cold outside, warm inside the house. Everything was fine until they realized that inside the warm enclosure the meat tended to spoil. So they built a cold enclosure—a refrigerator—inside the warm enclosure. Warm in the house, cold in the refrigerator. Everything was fine until they realized that inside the cold enclosure the butter got too hard to spread. So they built an even smaller warm enclosure—a butter warmer—inside the cold enclosure, which was already inside the larger warm enclosure. Strange.
