4th of July firework colors come from different elements of the periodic table — here’s what fuels red, white, and blue stars in the sky

A 4th of July fireworks show is about more than just gunpowder. Stars of color shoot into the air, each with a specific elemental composition.
Pictured above is the former location of Manhattan's Beacon High School, where a student was badly burned in a botched chemistry experiment in 2014.

A high school chemistry experiment that went horribly wrong left a boy permanently disfigured, and a jury just awarded him $60 million

Alonzo Yanes was 16 years old in 2014 when he was left badly burned from a botched chemistry experiment conducted by his teacher, Anna Poole.
Many actors aim to achieve sexual chemistry with their love interests on the big screen.

7 signs that you have sexual chemistry with someone

Though there's a good chance you're both feeling it, there are obvious signs that you have sexual chemistry with someone. Here they are.
A Soviet-era nerve agent called Novichok was likely used in the March 2018 attack of a former Russian spy and his daughter.

Novichok is a ‘dangerous and sophisticated’ Soviet-era nerve agent — here’s how it works and why it’s so lethal

Novichok, a rare and highly toxic Soviet-era nerve agent, was used to attack former Russian spy Sergei Skripal and his daughter Yulia, UK authorities say.

The fascinating chemistry that goes into a fireworks display

The spectacle of a fireworks display may leave you wondering how that dazzling sequence happened in the sky. From the explosion to the dazzling colors, there are a lot of chemical reactions happening in your 4th of July fireworks.
Saturn's moon Enceladus sprays saltwater into space from a hidden ocean. NASA's Cassini probe in 2015 "tasted" organic molecules in the water while flying through the icy plume.

NASA ‘tasted’ complex organic compounds in a blast of water from one of Saturn’s moons — and can’t yet rule out the poss...

Enceladus, an ice-encrusted moon of Saturn, hides an ocean of saltwater that blasts ice into space. NASA flew its Cassini spacecraft through the ice geysers in 2015, and scientists detected complex organic molecules. Though not proof of alien life, it's a good sign for the habitability of Enceladus.
Mmm, coffee.

Brewing a perfect cup of coffee requires the right water — and pure H2O is the worst kind

Water — the biggest ingredient in coffee by weight — can make or break the flavor of a freshly brewed cup. Some beans are better suited to hard or soft water.
