Vulcan 1500g Crackling Fountain from Klasek Fireworks
Yes thats right this fountain contains an incredible 1.5kg of powder making this the heaviest fountain we have ever seen.
Like all conical fountains this starts of relatively small and it just keeps getting bigger and bigger before the silver crackling stars eventually hit heights of around 7-8m.
