Flash mobs usually do dance routines in malls or train stations. But not this new flash mob video on YouTube

Someone placed an empty plastic bottle on the floor next to a recycling bin in a shopping mall food court, then waited to see how long it would take before someone picked it up and put it in the bin.

About 25 people walk by without picking it up, and when a girl finally recycles it,
the mob gives her a 30 second standing ovation.
