Chunnel Digging Under Extreme Pressure
📝 Script
Massive forces build beneath the sea as the Channel Tunnel is carved underground. Digging starts deep underwater before the tunnel plunges 75 meters beneath the seabed. The Tunnel Boring Machine 'Mary' spins relentlessly, grinding through tough chalk marl rock. Pressure rises as the machine pulls forward, causing the surrounding earth to tighten and compress. When thrust force exceeds 32,000 kilonewtons, the tunnel face can rupture, risking collapse. This underground corridor transforms the seabed, sustaining immense pressure long after digging stops. Follow for one real science fact every day.
