This would be an extra large diameter slinky optimally sized to walk down an escalator.-- goldbb, Jul 14 2009 Escalator Slinky http://www.youtube....watch?v=ASxPwiZOlPEThis one did pretty well [csea, Jul 14 2009] E-S take 2 http://www.youtube....watch?v=YJw0L7fxbF4This one is less well suited, takes multiple steps and gets stuck... [csea, Jul 14 2009] upon searching "extra large slinky" http://www.hometrai...t.asp?pn=MC-SLINKY2I know, I know. My websearch prowess is impeccable. [daseva, Jul 20 2009] This is brilliant! Presumably, it's walking down an upscalator? And its walking speed would match the escalator speed, producing a perpetual walking-on-the-spot effect?-- MaxwellBuchanan, Jul 14 2009 There are a number of YouTube videos showing attempts with normal-sized slinkies. [links]-- csea, Jul 14 2009 Thanks csea, I tried searching myself, and found videos of several failed attempts to send a regular slinky down an escalator (including the second one you linked to), but wasn't persistant enough to find that first link you posted :)-- goldbb, Jul 20 2009 How big? <link>-- daseva, Jul 20 2009 Bun if the idea is as [MaxwellBuchanan] describes.-- simonj, Jul 20 2009 random, halfbakery
