Unscramble the Blue Letters
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 plcae on erath, they work inside a refgioerartr. As they hdnlae the ice, in fact, they keep an extra pair of gloves warming in an oven, so that, when their work gloves frzeee and their fingers stiffen, they can don a fresh pair. They work against the cclok and against the tthmmreeeor.

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.
