Imagine you are about to catch a flight home, or you're getting to an airport far away as Dubai and you are surprised by a massive dance. This flash mob at the airport in Dubai will give you an idea.
For those who do not know what it is this, say a flash mob is a staging by people in a public place to meet, such as a choreography, so it may seem "spontaneous".
These meetings began in 2003 when Rob Zazueta created a page, which began to organize these meetings, which often are created for entertainment, but also sometimes carried out for political reasons.
Today, with little spontaneous about because it shows that there are many hours of rehearsal, professional dancers and choreography carefully studied. But the looks of surprise from those not, is still the best prize.
