One of the most eagerly awaited by many audiences from around the world some time ago might be "The London 2012 Olympics Opening Ceremony", which took place at 9 pm London time (4 pm ET) on Friday, July 27. This has always been an interesting thing to watch every four year. Besides the art show itself, which was directed by Danny Boyle, one thing that catched people's attention that night was the Olympic Cauldron used. Each host country is always prepared interesting and different cauldron to always give the good impression, even to its ignition procession. At the beginning, it seems there is nothing special about the cauldron used, even less likely to have a shape like a torch. Thought was instantly changed when one by one "petal copper" lit and long pipes began to move automatically, very beautiful indeed for a cauldron ignition procession.
The cauldron was designed by Thomas Heatherwick. Featuring 204 copper petals, each representing one of the competing nations which were brought to the stadium by each team as part of the athletes’ procession, the petals were then attached to long pipes in a ring at the centre of the arena. In the climax of the ceremony the individual flames spread between the petals, converging on the cauldron to create one giant flame.
The cauldron was developed at the Heatherwick Studio in Kings Cross, London, which Heatherwick founded in 1994 with the aim of “bringing architecture, design and sculpture together within a single practice.
