How do you make a tunnel interesting? Well luckily, this week's subject, the Thames tunnel needs no help at all. We take a look at how the first tunnel under a river anywhere in the world is so much more than just a tunnel, how we nearly lost one of Britain's greatest ever engineers, and how you can still travel through this tunnel today.
Plus we find out who won the Podcast Pedestal, and we spin the Wheel of Destiny to find out where we are going next!
