What is fire? Is it a solid, a liquid, or a gas?

Sitting around a campfire, you can feel its heat, smell the woody smoke, and hear it crackle. If you get too close, it burns your eyes and stings your nostrils. You could stare at the bright flames forever as they twi...

Glaciers flow like rivers, a time lapse

Though they look solid and still, gigantic compressed masses of ice called glaciers flow, constantly moving like rivers. In this Secret Life of Ice clip, we see their awe-inspiring shifting with help from a time-lapse...

Cooling without polluting: Two new green air conditioning innovations

The starry night sky seems remarkably distant from the topic of air conditioning, but it’s revolutionizing the field in quite an unexpected way. In this episode of "The Spark," watch how scientists from across the glo...

The Meissner Effect: How to levitate a neodymium magnet

A neodymium magnet cube sits on a surface of yttrium barium copper oxide—YBa2Cu3O7, nicknamed YBCO—inside the bottom of a styrofoam cup. A small amount of liquid nitrogen is poured slowly over the YBCO. As it cools, t...

What happens to balloon animals in liquid nitrogen?

How can you fit a bunch of balloon animals into a small container? Add some liquid nitrogen into the mix, as demonstrated in this video by Real Physics Live, the YouTube channel for Texas A&M University's Department o...

Why do we confuse weather and climate?

Weather and climate are not the same things, yet we might get confused between the two. What is weather and what is climate? And how is climate like the game Plinko? In this episode of PBS Digital Studio's Hot Mes...

FROSTYLAPSE II: Window frost forms in time lapse

Capturing around four to seven hours of real time freezing, each of these clips shows how ice crystals form on a very cold kitchen window. The time lapses were animated from around 55,000 photos in total, taken in Win...

How long have we known about climate change?

What is climate change, how long have we known about it, what will its effects be, and what can we do to help solve it? Hot Mess is a new PBS Digital Studios YouTube series from hosts Miriam Nielsen, Talia Buford, and...

Levitating pumpkins! Halloween superconductor science

What happens when you put a cooled superconductor, in this case, a YBa2Cu3O7 ceramic disk, into a tiny pumpkin and then place them both onto some neodymium magnets? Levitating pumpkin! In this Ri Channel video, su...

Why America still uses Fahrenheit

Since I've moved to the US in 2010, there's one thing that I still don't fully understand: the imperial system. Virtually every country on earth uses Celsius but America has yet to follow. Although it might not seem l...

How Do Glaciers Move?

Glacier ice is weird. It’s solid. Solid things aren’t supposed to flow. But glacier ice flows like a liquid, and it does that without melting! How is this possible? Travel to Alaska's Mendenhall Glacier with Joe H...

How to spot a misleading graph

When they’re used well, graphs can help us intuitively grasp complex data. But as visual software has enabled more usage of graphs throughout all media, it has also made them easier to use in a careless or dishonest w...

Step into a summer igloo (in 360°) as it’s being built

Though they're made from blocks of compacted snow, igluit (igloos) keep their residents well-sheltered by insulating from the cold and wind outside. In this 360° video from The New York Times, Adami Sakiagak and Tiisi...

Sandwich Bag Fire Starter

The intensity of sunlight on Earth is about 1300 Watts per square meter. When you focus the sun's rays using a magnifying glass (or in this case sphere of water) you can increase the intensity roughly ten thousand fol...

How dead is the Great Barrier Reef?

Australia's Great Barrier Reef is the largest coral reef system in the world and the only living structure visible from space. Although ecosystem managers in Australia have worked hard to preserve the reefs, the past ...

The Arctic vs. the Antarctic

If you're first learning about them, the Arctic and the Antarctic might be a bit confusing. Which one is which? Where are the penguins and where are the polar bears? Which is made of melting ice and which is a desert?...

Readying the Webb Telescope for Launch

Launching "the most sophisticated space science telescope ever constructed" into space is a complex process, and testing is a huge part of it. The James Webb Space Telescope's intricate hardware and technical systems ...

The scientist that grows ‘identical twin snowflakes’

Snow crystals form when humid air is cooled to the point that molecules of water vapor start sticking to each other. In the clouds, crystals usually start forming around a tiny microscopic dust particle, but if the wa...

Not finding what you're looking for? A few suggestions:
• Fewer words might give better results. Look up cats instead of funny cats.
• No need to search with the words videos or for kids included.
• Use related words: If searching for iceberg isn't working, try ice or glacier.
• Is everything spelled correctly?
• Browsing topics might help, too!
