Why does an escalator handrail move faster than the stairs?
Veritasium dives into the surprising science behind escalators—from the very first patent to the hidden mechanics that keep them humming. You’ll learn how those ridged steps and bristly brushes aren’t just for show, why you can actually generate electricity by riding one, and what happens when things inevitably go wrong.
The real star, though, is the handrail: it’s geared to skid ahead of the steps, giving you just a split-second boost as you climb. Along the way, you’ll get the lowdown on escalator safety features, breaking systems, and why maintenance (shout-out to the OTIS team!) matters more than you’d think.
