Fireworks!
(Actually, let's call it applied chemistry & physics.)
Here's a short video from the American Chemical Society about the chemistry of fireworks, for your Fourth of July enjoyment. You also might like this article from Mental Floss which explains the chemistry of different fireworks colors.
Science News for Students has an article that also looks into some of the physics and engineering challenges involved in creating a pyrotechnics show-- including pictures of a record-breaking shell that created a fire-burst 1 km (0.6 mi) in diameter!
