Cambridge Ballet Flashmob
Thirty dancers from the Cambridge University Ballet Club staged an impromptu dance in the Lion Yard shopping centre on Saturday.
The dance was choreographed to music.
Caroline Radnofsky, a member of the Cambridge University Ballet Club, said: "One of the coolest thing about flashmobs is that they are like living in a musical.
It's like everyone's fantasy where everyone just stops what they're doing and starts dancing in the most mundane situations, like shopping on a Saturday."
