The sky must be flooded with an array of colors patterns, colours and effects. Shhhh! Don’t divulge to anyone the fact that in reality, there are just several types of fireworks. There are however many different effects that result from these types, and this is where the skill of the designer comes into play.
In this article, we’ll explore the various types and what the overall impact of them is and therefore the way they can be used in a display.
Roman candles form the most common food of a fireworks show, lasting up to 30 minutes and offering the ability to continue. They can produce a range of effects including, comets, bombettes and mines or crossettes, butterflies and serpents. There are also noise effects like flash reports, hummers, whistles, crackle and screechers. Usually eight shots per candle they are either fired singly at regular intervals across the length of the area or in bouquets of 3 5, 7, or 6 and are angled to create a lattice, or different designs within the skies.
They are among the most well-known types of consumer firework and are used to describe all the things you see in the sky! A rocket motor at the end of a stick moves the pyrotechnics payload up into the sky and explodes to create an impact at the trajectory apex. The sound of the rocket motor, usually accompanied by an silver or gold tail, is a typical sound of a TV sound engineer wishes to present “BIG” fireworks. Ironically the professional industry employs fewer rockets because the stick and the rocket motor come back down. If you are buying a rocket at the shop, beware of the huge head which is usually full of air and created to convince buyers to purchase it. bigger isn’t always better with rockets!
Cakes, Combination Batteries, or Cakes
Combination Batteries or Cakes as they’re popularly known (because they look like cakes!) are a very popular alternative to ensure continuity
and display duration. They are composed of shorter tubes that are bonded together to fire in succession – sometimes very rapidly and sometimes very slowly. They’re similar to roman candles with regard to many effects that are produced by the tubes, however they are pre-angled, so the effects on the ceiling of fans and z-shaped, w shapes and varying speed of ignition create many possibilities. Cakes come in a wide assortment of sizes ranging starting from a tiny 19 shot bubbling willow cake to a large 600 shot rapid fire peacocks tail battery. The first is designed to give an effect similar to a normal roman candle, whereas the second will fire an enormous fans of over 600 effects within 8 seconds to create a huge peacock’s tail that flies in the sky.
