A helium filled bubble the size of St Paul\\$quot;s Cathedral has become the latest unique addition to London\\$quot;s skyline.
The spectacular ovoid-shaped inflatable canopy, created by world famous architect Rem Koolhaas and structural engineer Cecil Balmond with Arup for the 2006 Serpentine Gallery Pavilion Commission, took eight hours to fill and floats over the pavilion at the renowned Serpentine Gallery, Kensington Gardens.
Illuminated at night, it is raised into the air in good weather and lowered in bad weather to protect visitors below.
BOC pumped more than 5,500 cubic metres of the gas into the canopy \\$quot;“ enough to lift two three tonne elephants into the air.
Each summer the Serpentine Gallery commissions an internationally acclaimed architect to design a temporary pavilion for its lawn. The 2006 exhibition starts on 13 July and runs to 15 October.
The Serpentine Gallery, built in 1934 as a tea pavilion, attracts 590,000 visitors annually to its exhibition, architecture and education programmes.
