Frost and the Wonders of Liquid Air
Frost can perform miracles. He can build a bridge across a river without an axe or a single nail, and he can turn water into a blue stone—ice. When physicists harness Frost’s power, he can turn air into a liquid, a flowing substance much like water. That liquid air pours from one container to another. But ordinary ice feels like a scorching hot plate to liquid air; the liquid boils against the ice as if over a fire, while the vapors themselves are intensely cold.
If you drop a lead bell into liquid air, it will ring like silver. Alcohol cooled in liquid air becomes solid. The solidified alcohol won’t ignite, no matter how many matches you strike. But with the slightest impact, those frozen materials can explode. Meat immersed in liquid air turns yellow and… glows in the dark. It’s not just meat: bones, bread, eggshells, and cotton cooled in liquid air also emit a glow.
That means Frost can give substances entirely new properties—properties we can use if we study them closely.
