What makes fireworks colorful?

It’s all thanks to the luminescence of metals. When certain metals are heated (over a flame or in a hot explosion) their electrons jump up to a higher energy state. When those electrons fall back down, they emit specific frequencies of light - and each chemical has a unique emission spectrum.

You can see that the most prominent bands in the spectra above match the firework colors. The colors often burn brighter with the addition of an electron donor like Chlorine (Cl). 

But the metals alone wouldn’t look like much. They need to be excited. Black powder (mostly nitrates like KNO3) provides oxygen for the rapid reduction of charcoal © to create a lot hot expanding gas - the BOOM. That, in turn, provides the energy for luminescence - the AWWWW.

Aluminium has a special role — it emits a bright white light … and makes sparks!

Even The Planes Stop Flying For South Korea's National Exam Day

Aircraft were grounded, the stock market opened an hour late and police officers gave free rides to students rushing to Korea's all-important college entrance exam.

“To live in modern South Korea is to live with constant pressure. The Suneung exam, it’s an emblem,” says author Daniel Tudor. Here’s our audio postcard on the big exam, from All Things Considered.
