We're going to switch gears now and tell you about a competition that is really about to take off - pun intended. We're talking about the nation's largest rocketry tournament, the Team America Rocketry Challenge.

If you think that making a model rocket is kids' stuff, listen to this: Teams must build a rocket that can fly as close to 800 feet as possible in about 45 seconds.

Some new photo-sharing apps have become popular precisely because the photos have limited lives. Facebook Poke and Wickr both make photos self-destruct. And then there's Snapchat, pictures last 10 seconds at the most. It is the most popular of this kind, especially among teens.
