Fireworks and Gunpowder: A Journey Through Chemistry and History

The video explores the history and chemistry of gunpowder, the construction and launch of fireworks, and the creation of colors and patterns in fireworks displays. It includes a demonstration of flying an FPV drone through fireworks and discusses safety measures and fuse types. The video concludes with a fireworks finale and a segment on KiwiCo's educational projects.
