It's the last round! You'll have to be a super-geek to get these...

1. If you start with amoeba, the natural end point is what?

2. What song did Let's Tea Party play at last year's Geek Pop festival?

3. What colour were Jim's wellies?

4. How many geeks does it take to change a light bulb?

5. What would you rather be: a wave, or a particle?

HINT: No hints today - this is the super-geek round!

Answers on a virtual postcard via Twitter (direct message us) or email (crew@geekpop.co.uk). At the end of the week, one lucky winner for each day's quiz will be sent a Let's Tea Party pin badge. And we'll send an Amateur Transplants album to the geek with the highest score after all five rounds. Questions 4 and 5 today are tiebreakers - go wild.
