I used to hear about flash mob but I don’t really know what it exactly means. According to a website, flash mob means a large public gathering at which people perform an unusual or seemingly random act and then disperse, typically organized by means of the internet or social media. If you still in doubt, Improv Everywhere will show you what is flash mob.
One night at New York City, Improv Everywhere makes a surprise flash mob. It is one of the latest prank that they made. What happens if someone flips the giant light switch?
In order to make this flash mob happens, this must be hard. I salute Improv Everywhere for making people feel great after seeing these shining light bulbs.
