If you are lucky enough to go to the Beijing Olympics make sure you take a trip to the National Aquatics Centre, otherwise known as the Watercube.
After 3 years of construction the World’s best swimmers will be competing in a cube of bubbles along with 17,000 spectators. What will be a surreal experience can only be surpassed by the shopping centre and nightclub that it will be converted to after the Games. It will certainly be a twist on the foam parties that the UK nightclubs put on.
The outside skin is made of the Teflon-like material known as ETFE, or ethylene-tetrafluoroethylene. Composed of two layers, it's separated by an interior passage that allows the building to breathe like a greenhouse.
