For centuries alchemists have tried to turn base metals into gold. But is such
a feat even possible?

In the final Christmas Lecture, Dr Peter Wothers explores the elements within
the earth and discovers just how difficult it is for chemists to extract the
planet's greatest treasures. He discovers how our knowledge of the elements can
allow us to levitate, turn carbon dioxide into diamonds and maybe turn lead
into gold.

Peter is joined by Nobel Prize-winning chemist Professor Sir Harry Kroto and
together they find out whether a member of the audience is really worth their
weight in gold and what happens when you set fire to a diamond.
