Summer school turns children into mini-engineers

29 August 2014 Last updated at 00:02 BST

When Patrick Hendra retired as professor of chemistry at the University of Southampton, he took up a new hobby - making model boats.

A compulsion to share knowledge led him to turn his hobby into a model-making summer school for the children at his local village youth club.

By building miniature boats, cars and even a bridge made primarily from coffee-stirrer sticks, Patrick is teaching the children to be young engineers.
