Blue Peter: Astronaut Training, Rubbish Puppets and Channel Tunnel

Barney meets British astronaut Tim Peake. As well as chatting to Tim about his planned mission to the International Space Station, Barney is put through his paces with some astronaut-training techniques. Lindsey helps maintain the longest undersea tunnel in the world, the Channel Tunnel, and the team's green campaign continues live in studio as they are joined by a theatre company who show them how to transform trash into puppets.
