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!

Contamination-seeking drones - IBM Patent 9447448.

Stay back and let the drones do the dirty work. Patent 9447448 makes cognitive drones able to inspect and decontaminate places so humans don’t have to. The drones’ on-board AI system can collect and analyze samples, so it can identify and clean up any bacteria or outbreak. Meanwhile you get to hang back, safely out of harm’s way.

This is just one of the record-breaking 8,000+ patents IBM received this year. Explore the latest IBM patents. →

I hate when people get all snobby like “uhm, humans didn’t EVOLVE from apes, humans and apes share a common ancestor”

Yeah well guess what shitlips, that common ancestor? an ape. By every taxonomical definition, it would be considered an ape.

.. I mean shit, by taxonomical definition, humans still are apes. They fall under the family Hominidae. We didn’t ditch that branch when we put pants on.
