For my sake, that video could have been about 3 minutes shorter and dropped the music all together.


I’m always amazed those things work at all and don’t even usually kill people in the process.

The one that go down aren’t escalators, they’re de-escalators. Check your Prince lyrics.


Stairs go up, stairs go down. Nobody can explain that.

“It’s really important that the handrail move at the exact same speed as the steps”

I don’t think i’ve ever been on an escalator where the match is perfect.
