This is the mighty Lush by the mighty Celtic Fireworks. A professional (category 4) cake that has been transformed into a consumer (category 3) firework for general use, and yet still produces breath-taking effects.
It is simply pyro artistry in the sky, if you want everyone watching to say 'WOW what a stunning firework' then get yourself a Lush. Producing a 'W' shaped firing pattern, this will truly stand out in your display.
Once again, another high-quality high-performance cake from Celtic Fireworks.
