Episode 22 of the Wonder of Stuff

So, we had all sorts of technical gremlins last night which meant that we had to postpone the show... However, I've had my screwdrivers out and I'm pretty sure that everything is now working so we'll hopefully be doing episode 22 live tonight at 20:00 BST (19:00 GMT) and it should be here: https://plus.google.com/u/0/+TheWonderOfStuff/posts
