Not really science related. Found this on SucceedBlog (thanks Geoff for the link).

Nobody wants to be the first person up and dancing right? Big props to this guy for getting the party started.

You start out with one guy dancing his bum off. Then another person joins in. Then another. Then all of a sudden everybody piles in. That’s the point of critical mass where the whole park gets the idea at the same time “Hey, let’s DANCE”.

I laughed at the last few stragglers in the vid I bet have no idea where they’re running to, or why. But since everybody is there… it must be the place to be, right?
