Scientific American and YouTube are offering teenagers a chance to participate in real science. It works like this: Think up a question that can only be tested via an experiment performed in space. Make a video about your idea and submit it to the contest by December 14.
The two best ideas will actually be tested in space. That's right. If you win this, an experiment you designed will be performed by astronauts aboard the International Space Station. And you'll get some cool stuff—like a zero-G flight on board the "Vomit Comet" now, and, when you turn 18, actual cosmonaut training in Russia. Yeah. For real.
Oh, and Stephen-freaking-Hawking will be one of the judges.
This whole thing is a little insane.
If you're between the ages of 14 and 18, and you live on Earth, you can enter. Do it. Seriously. There are grown-ups who want to live vicariously through you.
For inspiration, here are some sample entries.
