#### Unscramble the Blue Letters

If you start on the pnealt and you go up and up and up, it gets colder and colder and colder, until you reach the biinnegng of the stratosphere, and then an amazing thing happens. It gets celdor at a much slower rate, and then it starts wnrmaig up, and then it gets warmer and warmer until the point where you can almost survive without any protection, about zero dereges, and then you end up getting colder and colder, and that's the top of the stratosphere. It is one of the least accessible places on our planet. Most often, when it's visited, it's by astronauts who are blazing up at it at probably several times the speed of sound, and they get a few seconds on the way up, and then they get this blazing ball of fire coming back in, on the way back in.

#### Original Text

If you start on the planet and you go up and up and up, it gets colder and colder and colder, until you reach the beginning of the stratosphere, and then an amazing thing happens. It gets colder at a much slower rate, and then it starts warming up, and then it gets warmer and warmer until the point where you can almost survive without any protection, about zero degrees, and then you end up getting colder and colder, and that's the top of the stratosphere. It is one of the least accessible places on our planet. Most often, when it's visited, it's by astronauts who are blazing up at it at probably several times the speed of sound, and they get a few seconds on the way up, and then they get this blazing ball of fire coming back in, on the way back in.
