Dum Dum is a 25 shot cake with 30mm tube and if you like loud fireworks then this one is for you. It has glittering swirls, silver tails and big bangs. It is classified as 1.3g and F2 so more flash powder than the everyday consumer fireworks. That you buy from the local supermarket. Dum Dum will reach heights of about 25m or 80ft to you and me. Our recommended firework safety distance is 25m from the public.
