Unscramble the Blue Letters

This process requires extraordinary precautions. The stieisncts must insure that the ice is not contaminated. Moreover, in this 8,000-mile journey, they have to insure this ice doesn't melt. Imagine jugnilgg a snowball across the tropics. They have to, in fact, make sure this ice never gets warmer than about 20 degrees below zero, otherwise, the key gases inside it will dissipate. So, in the coldest place on Earth, they work inside a rerroiefagtr. As they handle the ice, in fact, they keep an extra pair of gloves wraimng in an oven, so that, when their work gloves fereze and their frgines stiffen, they can don a fserh pair. They work against the clock and against the thermometer.

Original Text

This process requires extraordinary precautions. The scientists must insure that the ice is not contaminated. Moreover, in this 8,000-mile journey, they have to insure this ice doesn't melt. Imagine juggling a snowball across the tropics. They have to, in fact, make sure this ice never gets warmer than about 20 degrees below zero, otherwise, the key gases inside it will dissipate. So, in the coldest place on Earth, they work inside a refrigerator. As they handle the ice, in fact, they keep an extra pair of gloves warming in an oven, so that, when their work gloves freeze and their fingers stiffen, they can don a fresh pair. They work against the clock and against the thermometer.
