The installation consists of a 15 metre long river of water running through a tunnel lined with thousands of gold coloured balloons. Visitors are dressed in white boiler suits, protective hats and wellies by 'security chief' Nelly Ben Hayoun and then taken through the tunnel on a small rowing boat guided by professional physicists from Imperial College and Queen Mary University. Passengers hear loud booms and see bright flashes of blue light -- Cherenkov Radiation -- that shake and shudder the gold balloons -- Photomultiplier Tubes -, replicating the real Super-K interactions between neutrinos and atoms of extremely pure water, the effects of a sonic boom, normally faster than the speed of light.
