This is an entirely too artistic video (just show the stair parts, dammit!) demonstrating Po-Chih Lai's Stair Rover, an 8-wheeled skateboard with pivoting trucks that allow it to be ridden down stairs. Me? I like to ride down stairs the old fashioned way: on a pillow like I did when I was a kid. From the look of things, the board probably won't work on any steep staircases, but let's not kid ourselves: you were gonna take the elevator anyways.
Hit the jump for a video of the not gonna lie, you probably could've ridden down those ultra-wide stairs on a regular skateboard.
Thanks to Lance, who once rode down the stairs on a greased cookie sheet and put his head through a wall. No way -- me too!
