Science → Engineering → Underwater Tunnels
Beakman explains how they make underwater tunnels using a fish tank with gravel in the bottom. He then puts a hamster tunnel in it to show how the hamster could get from one side to the other without getting wet. They then show a clip of how the Chunnel was made between England and France.
