The best submissions will be conducted aboard the ISS and the winners will receive some out-of-this-world prizes.
YouTube has launched Space Lab, a collaboration that gives 14-18 year olds the chance to design a science experiment that could be carried out on the International Space Station. Entrants need to submit a two-minute proposal in a video uploaded to the site and a panel of judges including astronauts, NASA chiefs and Professor Stephen Hawking will pick the winners, with input from YouTube users.
The competition has been designed by the company to promote its educational resources and science-related output. The winners will be awarded prizes including a zero-gravity flight, laptops, a trip to see a rocket launch, and an astronaut training experience. The two best experiments are due to be carried out in space next summer.
