How to Sell a Slinky

Did you know playing with a Slinky can be a performance art? This vendor makes his Slinky do things you can't, because it takes practice. This kind of juggling would really screw up the old school metal Slinkys, and probably wouldn't look as good, either. Wouldn't you love to see this in fluorescent colors under a blacklight? The guy would probably be pretty good with a yoyo, too, if he gave it a day or so. Now I really want a plastic rainbow Slinky. (via Metafilter)
