Job Title: Lord Brainiac

Favourite series three experiment: What's the best food to use in a food fight? Those Brainiacs really know how to chuck their lunch about.

Favourite new Brainiac strand: Break or Bounce with Professor Myang Li. She's worth the Sky subscription on her own.

Can you tell us what's on the Brainiac DVD? The best of Series one, behind the scenes footage and some of the more 'unexpected' moments. I can't say much more but prepare to be amazed!

What's it like to work with Jon Tickle? Very good because he can deal with all the sciencey bits of the experiments - and also means I don't have to do all the messy stuff like swimming in syrup.

What do I have to do to become a Brainiac?Go to a surgeon and ask him to scrape out all the bits inside your skull and put the lid back on. You're now ready to start.

Got any Brainiac gossip you’d care to share with us? Two of the Brainiacs snogged at the end of series party.
