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.
