[11:38.77]The last reading.
[11:40.99]Flash Mobs
[11:42.62]A flash mob is where young people suddenly gather
[11:46.02]in a large group for no apparent reason.
[11:49.77]Flash mobs can involve hundreds of people
[11:52.25]who do not all know each other.
[11:55.05]But they all meet at the same time, then leave the area quickly.
[12:00.31]A flash mob can be held for any reason,
[12:03.54]but usually just to have some fun.
[12:06.94]The people involved in a flash mob
[12:09.37]do not know the time or place of the meeting
[12:12.96]until just minutes before it takes place.
[12:16.20]They get the details from a web site,
[12:18.79]or by e-mail or as a text message on their wireless phone.
[12:23.64]What do people do at flash mobs?
[12:26.68]Flash mobbers in a store will all ask for the same product.
[12:31.38]On a street, they may sing a song at the same time,
[12:35.23]shout meaningless words, hug each other or make some kind of noise.
[12:40.66]Then, just as quickly as they came, they leave.
[12:45.22]It all happens in a flash.
