The Sochi Winter Olympics closing ceremony has poked fun at the opening ceremony's failed attempt to open up an Olympic ring two weeks ago.

At the Fisht Olympic Stadium, a group of performers had been forming a variety of shapes of increasing degrees of difficulty during the ceremony.

Towards the end of their presentation they created four Olympic rings, with a closed one in the top right.

Eventually the shut ring opened up to unveil a full set, as per the standard Olympic logo, and a few bonus fireworks were let off.
