Tim Peake: Pupils to grow rocket seeds flown in space

Tim Peake is sending a recorded message to thousands of schools asking for help in a scientific experiment.

He will send seeds that have been on the International space station back to Earth so that half a million schoolchildren can grow them and discover how they are affected by conditions in space.

BBC News has had an exclusive first look at the video message - along with pupils at a school in Staffordshire.
