Can you teach an old spider new tricks? Could better understanding alien superbugs cure diseases on Earth? These are the questions that will be asked by the two winning experiments of YouTube Space Lab, the science competition that challenged students from 14 to 18 years old to design a science experiment that could be performed in space. Your votes and our expert judges chose the winners from thousands of entries from around the world. Experiments submitted by Dorothy and Sara, from Troy, Mich., U.S. (winners in the 14-16-year-old age group) and Amr from Alexandria, Egypt (winner in the 17-18-year-old age group) will be performed aboard the International Space Station and live streamed to the world on YouTube.

Sunita Williams—the NASA astronaut who’ll fly to the International Space Station later this year and perform the winning experiments live on YouTube—announced the global winners at a special ceremony in Washington, D.C., where the six regional winning teams were gathered. While in Washington, all the teams also took a ZERO-G weightless flight and a private tour of the the Udvar-Hazy Air & Space Museum.

In addition to having their experiments performed in space, Amr, Dorothy and Sara get to choose between one of two awesome space adventures: a trip to Japan to watch their experiment blast off in a rocket bound for the ISS or, once they’re 18 years old, a week-long astronaut course in Star City, Russia, the training center for Russian cosmonauts.
