The cheeky girls pay a visit to the Brainiac lab. Tina Turner and her bunsen burner are back with a bang. Jon Tickle takes the p out of science and drinks it. We try and stop rock and roll with the help of a chainsaw. Plus your chance to vote and win a starring role on the final show of the series as Brainiac goes interactive with explosive of the week.
