Garth and Bev - Air Filled Tyre

Animation about a time-travelling brother and sister called Garth and Bev, who live in harmony with nature in their village long ago. They are transported to different times and places by the Time Spiral and solve problems with the help of Grandfather Lir. Garth and Bev need to help Hoyt the potter carry his pots to market without breaking any. With a little help from some froggy friends, the children discover bouncy frog's cheeks are the perfect way to separate the pots and keep them safe. That's a bit like how John Dunlop filled rubber tubes with air to keep people from rattling around on their bicycles!
