ESA astronaut André Kuipers spoke live from the International Space Station with delegates at CeBIT, the world’s largest digital trade show. André answered questions from German Chancellor Angela Merkel, as well as two participants in the YouTube Space Lab competition, German students Sara and Simon Kopf.

The call took place during the opening event of CeBIT.
Sponsored by YouTube, Lenovo and Space Adventures together with ESA, NASA and the Japanese space agency, the international student contest is now in the final round of judging.
The final winners will be announced in March and their experiments will be performed later this year on the Space Station and live-streamed on YouTube as part of a global event celebrating science and space.
