Sparkling fireworks present a unique beauty produced by the black body radiation and not by flame reactions like other fireworks. Surprisingly, the beautiful streaks of light are bright droplets. One droplet ejected from the mother fireball successively bursts up to ten times and creates hundreds of daughter droplets, which become the light streaks similar to pine-needles. In this video, the world’s first image of successive fragmentation of self-luminescent droplet is shown.
