x-change 2013 - day 1

Welcome to Day 1 at the x-change and what a fantastic day it's been!

We've had everything from dinosaurs to robots, with some musical comedy and maths magic thrown in.

Check out the podcast presented by BBC journalist and Space Boffin Richard Hollingham. You can listen to the whole show or select a speaker from the playlist.

Read our volunteers' blog for a first hand account of the day's show.

For a rundown of the day's guest check out the show line-up.

Remember, we have a complete new line-up each day so visit the x-change pages to see what we have for our other 3 shows...
