Kate investigates eucalyptus. It's found in throat lozenges and chewing gum, but what exactly is it, where does it come from, and why is it so good at clearing the airways? In Australia, Kate meets one of the world's cutest animals: the koala, raised from birth on a diet of eucalyptus.

To find out, Jimmy visits a very chilly Poland, the home of sauerkraut, before learning about a remarkable new use for sauerkraut juice in a French power station.
