The Secret Genius of Modern Life S02E06 - Lift

Hannah goes behind the scenes to look at the technology behind the lift, entering a 246m high lift shaft to test everything from the brakes to her own fear of heights.

Along the way, she finds out how rickety 19th-century coal mines made lifts safer, gets to grips with a piece of medieval siege technology still used in lifts today, and discovers how an 1850s PR stunt changed the modern skyline forever.
