Before the Olympic Games in Sochi, Russia, snowboarder Sage Kotsenburg, 20, had never attempted a 1620 Japan air mute grab, which involves spinning 4 1/2 rotations while grabbing the toe end of your board with your front hand and pulling it just behind your back. He first tried it on his final run during the Olympic debut of men's slopestyle on Feb. 8. His risk paid off - he became the first official gold-medal winner at the Sochi Games and the first-ever gold medalist in the men's event.
Hay fever's real name is rhinitis (rye-NEYE-tis). People who suffer from hay fever are allergic to pollen and other particles in the air, which affect some part of the nose. As a result, a person might have itchy, water eyes, a stuffed nose, or a drippy throat. Dust mites, animal dander, mold spores and fabric fibers also can cause hay fever. Nearly 15-20 percent of Americans suffer from hay fever. Roughly 10,000 children in the U.S. miss school each day because of hay fever.
It might be cool to have a green sky for a day or two, but don't count on that happening. During a clear day, the sky is blue. Why is that? Light from the sun, which is made up of different rainbow colors, has to pass through atoms of nitrogen and oxygen in the atmosphere. Because those atoms are so tiny, they cause light to break up. The atoms break up the color blue much more easily than they do other colors.
