Haii , welcome back . . . 
Now i want to tell about Flashmob. Do u know 'bout Flashmob? Have u hear about that? Nahh, i want to share about that.
A flashmob is a group of people who assemble suddenly in a public place, perform an unusual and sometimes seemingly pointless act for a brief time, then disperse, often for the purposes of entertainment, satire, artistic expression or—in rare cases—violence. Flash mobs are organized via telecommunications, social media, or viral emails.
One of the first flash mobs was created in Manhattan in May 2003, by Bill Wasik, senior editor of Harper's Magazine. The first attempt was unsuccessful after the targeted retail store was tipped off about the plan for people to gather. Wasik avoided such problems during the second flash mob, which occurred on June 3, 2003, at Macy's department store, by sending participants to preliminary staging areas – in four prearranged Manhattan bars – where they received further instructions about the ultimate event and location just before the event began.
