Students ages 14-18: Have a big idea for an experiment that can be done in space? Bring it! That is, describe it in a video and post it to YouTube Space Lab by December 14. Your idea might be one of two that will actually be built and flown aboard the International Space Station. You'll also be eligible for some other cool prizes. I'm one of the judges, and I'm looking forward to seeing your ideas. Here's my YouTube Space Lab call for entries.

I visited "Wake Up with Al" on The Weather Channel a few days ago, and talked to Al Roker about the competition.
