What Makes A Firework Whistle?

Whistle!

The vast majority of people may well have heard a firework ‘whistle’ but never asked what creates the sound.

We all know that they make beautiful images in the sky but digging deeper, I was surprised with the results of my findings.

Like most people I was under the impression that the noise was created wholly by the position of the holes or vents in the firework tube, but, it appears that this is not necessarily the complete story. Although some of the sounds may be as a result of the construction, for the most part, it is the salts in the firework composition which will make the sound. Potassium Benzoate is the Potassium salt of a Benzoic acid which is also used as a food preservative as it inhibits the growth of some mould’s, yeasts and bacterium. When the oxidiser and the Potassium Benzoate burn’s, a layer at a time, it emits the gases produced in spurts creating the whistle effect and a rather pretty pink hue.
