Science can help solve the world’s most important problems, and what could be more important than keeping pee off your shoes? Yes, even the lowly urinal—and those who use it—can benefit from the occasional peer-reviewed study. So let’s...

I love coffee. Like, a lot. You know who else loves coffee? Astronauts! And also the people who help them do awesome things in space (I think NASA might be powered by coffee). But how do astronauts actually drink coffee in space, aboard...

We here at SciShow compiled a list of videos based on popular requests. Hank Green hosts with this winter themed episode!

Dr. Shini Somara joins us on the Talk Show today to talk Crash Course Physics and her background in fluid dynamics and television. Then Jessi from Animal Wonders brings on Sydney, their Brush-tailed Bettong.

You might think that fish ride the undercurrents with all their buds to avoid the hungry mouths of predators - safety in numbers, right? But, it turns out, there’s more to consider when asking why fish swim in schools.

You might consider humans or beavers to be the best engineers on the planet, but these 5 other animals go to great lengths to put our houses and dams to shame. Chapters SOCIABLE WEAVER 0:38 GREAT BOWERBIRD 2:13 PUFFERFISH 3:39 4 ORIENTAL...

Biologist Sheila Patek talks about her work measuring the feeding strike of the mantis shrimp, one of the fastest movements in the animal world, using video cameras recording at 20,000 frames per second.

Sometimes being in a traffic jam can feel like being stuck in a clogged pipe. And it turns out, maybe that feeling isn’t too far off. Today we look at 3 things that are remarkably unlike fluids, yet still behave in liquid-like ways.

Fixing traffic seems easy—just add more roads, right? Turns out that this is a problem studied by physicists and psychologists alike, with no easy answers.

A look at what turbulence is (in fluid flow), and a result by Kolmogorov regarding the energy cascade of turbulence.

Dive into the science of ocean currents (including the Global Conveyor Belt current), and find out how climate change affects them. -- In 1992, a cargo ship carrying bath toys got caught in a storm. Shipping containers washed...

You're on an airplane when you feel a sudden jolt. Outside your window nothing seems to be happening, yet the plane continues to rattle you and your fellow passengers as it passes through turbulent air in the atmosphere. What exactly is...

Airplanes use a lot of fuel, which means a lot of CO2 emissions. So, to help reduce the impact of aviation, engineers are looking to animals (like sharks) for some ways they can make airliners more efficient.

Birds fly, and fish swim. We learn this when we are children. But not everything in nature is quite so simple… Meet Limacina helicina, an artic-dwelling sea butterfly that flies through the water.

You may have heard of the butterfly effect, where butterflies flapping their wings somehow cause tornadoes. Although it seems pretty unlikely, butterflies can affect the weather, just not in the way you might think.

The terminal velocity of an object is the speed at which the force of drag equals the force of gravity on that object.

Today we’re talking all about fluid mechanics! We’ll look at different scales that we work with as engineers, mass and energy transfers, the no-slip condition, stress and strain, Newton’s law of viscosity, Reynold’s number, and more!

This week, Dr. Shini Somara goes toe to toe with Hank in a battle of wits about fluid dynamics and life in space.

Today, we continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places change water flow? And what is one of the motion annoying things about filming outside on a...

If you've ever taken a science or math class, you've probably seen the name "Bernoulli" -- and maybe you assumed it was one person, but that family had a squad of mathematicians.

Watch two soda cans mysteriously move toward one another using nothing but air—and phys

Watch the continuity equation of ideal fluid flow in action using a real river example. A clear, visual explanation perfect for physics students.

Explore laminar flow and streamlines with this animation of ideal fluid particles moving through a narrowing pipe. See how particle paths and streamlines illustrate fluid motion, perfect for understanding fluid dynamics.
