Season: 2 | Episode: 6 | Length: 60m
Hannah Fry examines the technology behind the lift, entering a 246m elevator 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 for ever.
