The good news is that your experimental robo-ants are a success. The bad news is that you accidentally gave them the ability to shoot deadly lasers . . . and you can't turn it off. Can you stop them from escaping their habitat before the...

Because you demanded it .... we break down the EM Drive!

Just how long could you survive on the surface of Mars without a spacesuit? Find out what it'd be like to stand on the surface of Mars, if you forgot to pack properly.

Michael Aranda explains the nuts and bolts of Hyperloop, the new magnet-driven, solar-powered transit system proposed by Spacex genius Elon Musk. Learn how Musk answered three vexing questions to create the transportation of the future...

Get to know Robert Goddard, one of the original rocket scientists!

It may be antiquated now, but the old pearl of wisdom: “Don’t sit too close to the TV” was good advice in the 1960s

Sound can't actually travel through a vacuum like space, but scientists have learned that there's still plenty to hear.

Most galaxies that we know of are spirals, including the Milky Way, but how do they form and keep their shape over billions of years?

A freshly-mopped floor is slippery, but a wet shirt is super-clingy... so what's the deal? Why can water make some things slick and other things sticky?

Humans are full of microbes. Humans also went to the Moon. Does that mean we left colonies over there?

Do you remember the exciting rumor about NASA’s EMdrive? Well, now it’s official: NASA has created their own EM drive! Meanwhile, SpaceX has a plan which will make the internet more accessible.

In this video Paul Andersen explains how electric permittivity of a material resists the formation of electric fields. Capacitors store energy be preventing the formation of electric fields in dielectric material. The electric...

Scientists have created beams of light that are slower than a car! Not only that, but with the literal flick of a switch, they can freeze that beam of light in place!

You know how you somehow end up getting smoke in your eyes wherever you stand around a bonfire? Well, it turns out that’s not a curse! It’s much more easily explained with physics. "The more protractors, the better the party." ~Hank Green

In this video Paul Andersen explains how the magnetic permeability is the ability of a material to form internal magnetic fields. The magnetic permeability of free space is a constant and is much lower than the magnetic permeability of...

In something like water, particles like electrons can beat light in a race - and cause a blue glow to prove it.

What is the loudest possible sound? What about the quietest thing we can hear? And what do decibels measure, anyway? In this video you'll learn what makes sound

How did life on Earth get started? Did life on Earth originate on another planet? Either Mars, or in a distant solar system? Could Earth life have spread to have seeded life elsewhere? Let's see what modern science has to say about the...

Without water, a human can only survive for about 100 hours. But there's a creature so resilient that it can go without it for decades. This 1-millimeter animal can survive both the hottest and coldest environments on earth, and can even...

Hank explains why NASA and the European Space Agency are in love with tardigrades and how these extremophiles are helping us study the panspermia hypothesis.

Meter is the standard unit of length used by most countries around the world. But how did they define it?

A barometer is an instrument that measures air pressure, allowing weather forecasters and scientists to better predict extreme weather events. Despite its incredible usefulness, inventing the barometer was no walk in the park. Asaf...
