Over the past two weeks 60 scientists have done more than 180 live chats and answered nearly 3,000 questions. We’ve been evicting scientists since Tuesday, and this afternoon we said Goodbye to 12 more. Now just two scientists remain in each zone, ready to battle it out for the £500 prize money, and the title of I’m a Scientist Champion!

The winners will be announced at 3pm on Friday, but for now, let’s take a look at your March 2014 finalists…
