In this paper we discuss the requirements of a firework, launched from the Attenborough Tower on The University of Leicester Campus, which would be capable of being viewed from any location in England. We calculated that the firework would need to reach a height of 14.3km, requiring 7.79g of gunpowder. The intensity of the explosion seen at the maximum distance from the Tower (Land’s End) would be 8.07×10−13W/m2, which we found could be produced by 1.1mg of Barium
