9．Don't be surprised if you see a group of people dancing or shouting on the square．They are a flash mob．Confused by their name？Actually，a flash mob，organized with the help of the Internet or other digital communications networks，is a group of people who gather suddenly in a public place，do something unusual for a period of time，such as exchanging books，coming together to look at the sky，waving their hands and shouting something at the top of their lungs for 30seconds，and then quickly disappear before the police can arrive．
Bill Wasik，senior editor of Harper's Magazine，organized the first flash mob in Manhattan in May 2003and the first successful flash mob gathered on June 3，2003at Macy's department store involving 100people gathering on Macy's Department Store．Following this，about 200people flooded the lobby of the Hyatt hotel，applauding in one voice for fifteen seconds，and next participants pretending to be tourists on a trip invaded a shoe shop in Soho．A later mob saw hundreds of people in Central Park making bird noises．
Wasik claimed that he created flash mobs as a social experiment designed to make fun of hipsters （趕時(shí)髦的人），and call attention to the cultural atmosphere．
Many web logs，chat rooms and Web groups are devoted to the craze．Though flash mobs were originally regarded as useless，the concept has already developed for the benefit of political and social events．Flash mobbing takes advantage of the efficiency of communicating information on Websites and by email，and protesters can similarly use the"on and off"concept to be involved in political events．Such flash mob gatherings can sometimes shock or frighten people who are not aware of what is taking place．They also have enormous economic potential，such as using flash mobs to advertise a product．
The flash mob is now becoming more and more popular．People use it to do many things．For example，in 2009，hundreds of Michael Jackson's fans took part in a flash mob to remember him，gathering outside the railway station in Liverpool，singing and dancing Michael's famous song Beat It together．In another example，some people took part in a flash mob to warn people against negative words．Flash mobs give people from all walks of life an opportunity to come together to create a memory．
