Students not only described their science experiment ideas via video, but also demonstrated and animated the procedures. The YouTube community will be invited to judge the entries, alongside judges including scientist Stephen Hawking and former astronaut Leland Melvin.
The two winners will have the experiments conducted 250 miles above earth, aboard the International Space Station (ISS) and streamed live on YouTube from a ThinkPad laptop as part of a global event celebrating science and space.
Winners will get to choose a unique space experience: A trip to Japan to watch their experiment blast off in a rocket bound for the ISS or, once they are 18, astronaut training in Star City, Russia, the training centre for cosmonauts.
Zahaan Bharmal, Google's head of marketing operations (Europe, Middle East, and Africa) and the man behind the idea of Space Lab, said, "They (students) rose to the challenge, demonstrating imagination, creativity and passion. Today's Space Lab entrants are tomorrow's space explorers."
