The Most Dangerous Escalator in Rome

Veritasium explores a notoriously risky escalator in Rome to uncover the surprising science behind every moving step—from the very first design to today’s modern safety features. You’ll learn why those grooves and brushes aren’t just cosmetic, how handrails actually outrun the steps, and even how you can generate electricity just by riding. Plus, Derek Muller dives into what happens when an escalator breaks and just how safe (or unsafe) they really are.

Along the way there’s a shout-out to Brilliant (20% off for viewers!) and the inventor’s own Snatoms kits, expert insights from OTIS engineers and professors, and a neat timeline that runs you through each segment—history, mechanics, electricity, braking, and overall safety. It’s a deep yet entertaining ride that turns a mundane piece of infrastructure into a fascinating mechanical marvel.
