Fireworks have been lighting up our autumn skies for centuries - but what鈥檚 actually going on inside those dazzling bursts of colour, sound and stars?

Hannah and Dara set out to discover the science behind the sparkle. From the chemistry that creates vivid reds, greens and blues, to the physics that launches shells high above our heads before exploding into perfectly planned patterns, they learn that every firework is a carefully choreographed feat of engineering.

Along the way, they explore why some fireworks whistle while others crackle, trace the remarkable history of fireworks from ancient China to modern-day spectacles, and ponder whether drones and laser shows could one day replace the traditional fiery festivities.
