How sparkler booms blow up?

Answer 1

Sparkler booms occur when the metal wire of a sparkler becomes overheated, causing the combustible chemicals to ignite rapidly. If the sparkler is lit in an enclosed space or if multiple sparklers are ignited simultaneously, the buildup of heat and gases can lead to an explosive reaction. This can result in a sudden release of energy, creating a loud boom and potentially causing injuries or damage. Proper handling and using sparklers in open, well-ventilated areas can help prevent such accidents.
