Frozen bubbles: Ice crystals form on bubbles in real time

Watch ice crystals form in real time on these spinning and floating soap bubbles, filmed in -40°C weather in Northern Sweden. The crystalized spikes grow outward quickly as the low sun lights the surfaces of the spher...

Minute Earth: Why Do Rivers Curve?

"...All it takes to turn a straight stretch of river into a bendy one, is a little disturbance and a lot of time, and in nature there's plenty of both." In this Minute Earth episode, narrated by science writer Emily E...

CYMATICS: Science + music = audio frequency visualizations

With help from a Chladni Plate, vibrating liquid on a speaker dish, a hose pipe optical trick, ferrofluid, a Ruben's Tube, and a Telsa Coil, New Zealand musician Nigel Stanford showcases audio frequency visualizations...

Non-Newtonian fluid bouncing in super slow motion (1600fps)

We've seen oobleck bouncing on a speaker before, but we've never see it in 1600fps super slow motion like this. Watch as The Slow Mo Guys color oobleck red, puddle it into an old speaker, and slow it way, way down. ...

Astronauts grow a water bubble in microgravity on ISS

Observing water in space is not only fascinating, but it clearly looks fun! Watch NASA astronauts Steve Swanson and Reid Wiseman, and European Space Agency astronaut Alexander Gerst create a floating bubble of water o...

The Hammer-Feather Drop in the world’s biggest vacuum chamber

...though in this case, "the hammer" is a bowling ball. In this excellent clip from the BBC's Human Universe: Episode 4, Professor Brian Cox visits NASA’s Space Power Facility in Ohio, home of the world's biggest vacu...

ScienceTake: The secrets of a sidewinder snake on a sandy slope

If you've ever run up a sandy hill, you know it can be tough to get up it quickly -- each foot sinking and sliding as you climb upward. Sidewinder snakes, however, can slither up hills rather efficiently, even in comp...

To the Scientists of the Future: Materials science with EUPHRATES

Created by EUPHRATES and Masahiko Sato for Japan's National Institute for Material Science (NIMS), these three "To the Scientists of the Future" short films are a mesmerizing combination of materials research innovati...

It’s Okay to Be Smart: Why Do Clouds Stay Up?

Clouds are filled with so many water droplets that they're actually heavy... like 100 elephants heavy or a 747 airplane heavy! So why don't clouds fall out of the sky? It's Okay to Be Smart's Joe Hanson explains every...

At-Bristol: How to make a hot air balloon

What is a hot air balloon made of and how are they made? Find out as At-Bristol Science Centre's Ross Exton visits Cameron Balloons, one of the world's oldest hot air balloon manufacturers, to learn more about the mat...

First Evidence for Water Ice Clouds Found Outside Solar System

Take a (peacefully quiet) tour through and beyond our solar system to visit a neighboring brown dwarf -- a sort of failed star that's too large to be called a planet -- called W0855. A team of scientists, led by Carne...

A pendulum wave demonstration with bowling balls

Thanks to these 16 bowling balls hung from a 20 foot wooden frame in the mountains of North Carolina, we can see what a large-scale pendulum wave apparatus looks (and sounds) like. Filmed by Maria Ikenberry, she also ...

Power of Optics: A light-powered Rube Goldberg machine

In this commercial for au Hikari, one of Japan’s high-speed optical internet service providers, a Rube Goldberg machine is "powered" by a single beam of light that travels via mirrors, magnifying glasses, and reflecti...

Laniakea: Our home supercluster

Our home planet, Earth, circles the sun. The sun, our star, is but one of billions of stars in the Milky Way, our home galaxy... and beyond that? Where on the map of the cosmos is the Milky Way? For the first time, we...

ExpeRimental: How to Make Balancing Sculptures

Physics! Engineering! Kinetic sculptures! Snacks! Learn about the science of stability (and instability) while making these delicious DIY balancing sculptures. In this episode of ExpeRimental, Ri's Director of Sci...

Skateboard tricks in slow motion

Watch skateboarder Christopher Chann in this slow motion skateboard trick footage shot by videographer Adam Shomsky during a six hour skate session in Los Angeles. Chann's trick list: Switch late hardflip Bigspin...

The Curiosity Show: How does a music box work?

In this clip from Australia's The Curiosity Show, science educator and co-host Deane Hutton demonstrates the basics of sound, moving air particles, and forced vibrations with a plastic comb, hacksaw blades, the metal ...

A match being struck as seen with Schlieren technique
