...example, one amateur proposed to study the facial expression of gophers under extreme pain by developing a device that would chop the animals' heads off the moment they emerged from their holes and drop them directly into a vat of liquid nitrogen so that their expressions would be preserved...
...Species, is the driving force behind a 25-year effort to assemble a bank of frozen dna, eggs and sperm from endangered species. Under his direction, the frozen zoo now has living cells from 5,400 animals spanning more than 400 species and subspecies, cultured and frozen in liquid nitrogen...
...that, by 1997, a whole group of them in California decided they couldn't wait any longer and left our soon-to-explode planet early. By 1999, Pat Robertson was selling tickets to seminars where people were taught how to store beans and corn in separate barrels sealed with nitrogen packs. He apparently figured God had traded in fire and brimstone for the more subtle New Year's computer...
...itself to the Pentagon's single, simple decoy. The enemy could slip its warhead inside a decoy balloon and deploy it along with a dozen identical balloons, forcing the Pentagon into a futile effort to destroy all of them. The warhead might be cloaked in a shroud of liquid nitrogen, chilling it so that the interceptor's heat-seeking sensors couldn't find it. Chemical or biological weapons might be deployed in dozens of bomblets far too numerous to destroy...
...will get the interceptor into the right neighborhood, but only the infrared sensors can guide it into its target, gently steering it with minithrusters powered by 30 lbs. of liquid rocket fuel. For the heat-detecting sensors to "see" anything, they must be chilled to -330[degrees]F using nitrogen and krypton, funneled to the sensors through a 0.0035-in. diameter pipe...
