Chemical Bouillon, a series of visually abstract chemical reactions

Hydrocarbon vs Ink - Implosion, above, from the Chemical Bouillon video series, "an artistic project studying the graphic aspect of chemical reactions" created by Antoine Delach, Valere Amirault, and Teurk in Paris, F...

Ferrofluid + Glow Sticks – The Physics Girl

Ferromagnetic + fluid = ferrofluid, a liquid containing nanoscale particles of magnetite, hematite, or an iron compound. Invented by NASA's Steve Papell in 1963, ferrofluid forms undulating spikes and patterns as it r...

The Real Reason Leaves Change Color In the Fall – MinuteEarth

Every autumn, green chlorophyll fades from the leaves of deciduous trees, revealing the underlying reds, oranges, and yellows. But why does the chlorophyll fade in the first place? Recycling! MinuteEarth explains. ...

What is Fire? – It’s Okay to Be Smart

That glowing light, those information-filled colors, that smoke and vapor that seems to magically light warm embers... What kind of physics and chemistry are at work inside of a flame? Joe Hanson from It's Okay to Be ...

Explore the Science Behind Fireworks—and the Galaxy

When you watch fireworks burst with color, you're seeing examples of how stars and galaxies work: Blues from copper, yellows from sodium, bright whites from aluminum, barium greens, and reds made from strontium... The...

Anodizing Titanium – “The Rainbow Metal”

Titanium is nicknamed "The Rainbow Metal" in some jeweler circles because it can be anodized in an electrolyte solution to produce a variety of colors. The colors are created by passing electricity through it to produ...

A solid, liquid, & gas at the same time – The Triple Point

How can a chemical be a solid, a liquid, and a gas at the same time? In the video above, a clear liquid called cyclohexane is experiencing the perfect pressure and temperature combination for its solid, liquid, and ga...

Microwave cake in a mug + How to make play dough – ExpeRimental

In this easy ExpeRimental science experiment for kids (and adults who want a cylindrical pancake with their morning coffee), we learn how to make microwave cup-cakes... or really, mug-cakes. And what happens if we ...

How to make fizzy bottle rockets – ExpeRimental

This ExpeRimental episode from The Royal Institution is full of super explosive fun. Danielle and Michael show a group of kids how to make fizzy bottle rockets with some small, sports-capped plastic bottles, some Alka...

Candle Chemistry – ExpeRimental

In this episode of ExpeRimental, Lisa and Josh explain the unseen as they make a flame jump through the air. Josh also measures how long it takes for covered candles to extinguish on their own. There's more activity i...

How to make bouncing eggs – ExpeRimental

Bounce, crack, dissolve, and make things a bit squidgy with stuff that's already around the house! The latest expeRiment from The Royal Institution is a classic for all ages: Olympia and her daughters, Viola and Elodi...

How Small Is An Atom?

Using a strand of hair, your fist, rice and sand grains, as well as the room you're sitting in right now (assuming it's not a huge gymnasium), let's try to visualize the basic building block of everything around us: A...

The Ring of Truth: Two Hydrogen Atoms & One Oxygen Atom

Possibly the most well-known scientific formula on the planet, H2O is one of those terms that we see around all the time. We know that H2O means water, and that a water molecule is composed of two hydrogen (H) atoms &...

Deep Look: The Crazy Cribs of Parasitic Wasps

These tiny wasps have a wonderful trick: they prompt oak trees to grow galls, abnormal plant tissue structures that shelter wasp eggs, by injecting a chemical under the tree's skin. If that was the end of the story...

Beautiful Chemical Reactions

Metal displacement, precipitation, crystallization, and more: This is Beautiful Chemistry, a 4K UltraHD short film project that aims to share how beautiful chemical reactions can be. From Tsinghua University Press and...

Why do leaves change color?

The arrival of autumn is a great reason to talk about chemistry: When tree leaves change from green to reds, oranges, yellows, and browns, we're seeing the tree's green chlorophyll fade away, revealing hidden autumnal...

The Chemistry of Rockets: How do rockets work?

How are controlled explosions made just right so that they'll generate the kind of thrust that sends a rocket up, up, up and beyond our atmosphere? Analytical Chemist Raychelle Burks, Ph.D., explains how solid and...

Sixteen year old Elif Bilgin turned banana peels into a bioplastic

After two years of research, experiments, and failed trials, 16-year-old Elif Bilgin developed a new process for turning banana peels into a non-decaying bioplastic, a more eco-friendly alternative to petroleum-based ...
