Master Engineering: The Thames Barrier

It is sometimes difficult to remember that our whole world is built on a sort of invisible infrastructure that allows us to go to work, take care of our children, and live our lives in peace. I had no idea that the river Thames in London, UK had a barrier to manage its tidal flows. It is a fascinating bit of engineering. It is vital that it never fail otherwise most of London would soon be underwater. In this video, we learn all about this special barrier and how it works.
