No beer in space: is there anything Chris doesn't know?

With Chris Hadfield, the world's most famous astronaut, cruising around Ireland at the moment as a tourism ambassador, he's still finding time to fit in his famous question-and-answer sessions about space.

So, naturally, it's time to ask the important queston: what's beer like in space?

A punk rock band from Hadfield's native Canada wanted to know, and what's even more impressive is that he knew off-the-cuff, and the answer is pretty damn cool.

Chris also answers some questions about playing guitar in space: does it stay in tune? What happens when you strum really hard? (Hint: gravity doesn't help.)

Meanwhile, as Mr Hadfield has been taking a tour of Ireland, he's managed to fit in a few more sights - including this famous staircase:

Do you recognize this location? The small statue is surprisingly unattractive. pic.twitter.com/RpPjp6RB4A

And he's brushing up on his Gaeilge too.
