A Knight, a Light-Day and a Snail on the Scales

Three stories in one episode. Your child will meet Sir Billy Boston, the rugby trailblazer who was turned away by his home city and became the sport's first ever knight, discover the spacecraft that is about to become the first object a full light-day from Earth, and visit London Zoo's annual weigh-in where even the snails take a turn on the scales. Along the way there is history, space science and a look at how zoos around the world share what they learn.
