As leading UK London firework display organisers we were proud to be invited to provide the display marking 100 years of the Isle of Man TT Festival's Mountain Course. The 15-minute firework spectacular was fired from a barge moored 200m offshore in Douglas harbour. It included our brilliant new waterborne fireworks, known as 'aqua cakes', floating in pretty coloured flares on the sea before erupting in a frenzy of noise and colour.
