Stanford’s µTug microrobots can pull a car

Watch six of Stanford's µTug (MicroTug) robots pulling an unmodified 3,900lb (1,800kg) car thanks to special directional adhesive "shoes" and "a very long, very slow, but very steady winching gate." The six microTugs ...

Bubble Device #4 at the Taipei Fine Arts Museum

From French Canadian media artist Nicholas Hanna, this is Bubble Device #4, another delightful video showcasing Hanna's automated bubble making device. The machine, which combines motors, pulleys, and a large fan, is ...

What happens when you put marshmallows in a vacuum?

Thanks to this hand pump vacuum sealer demo, we can see how these four fluffy marshmallows will react when the air is pumped out of their clear container. Poof, poof, poof! What's going on here? From Physics.org: ...

A levitating top in a foggy soap bubble

A spinning Levitron Cherrywood top, thanks to repelling magnetic force in the base and the top's gyroscopic stability, hovers over a soap bubble full of glycerin fog, all within a larger bubble that is also filled wit...

Concrete Does Not Dry Out – Minute Physics

If you've ever made pasta, you know what happens when you drop the noodles into a boiling pot: They absorb the water. Why? Pasta dries from an elastic dough as its water content evaporates. Compare this to concrete, "...

LIGO & The First Observation of Gravitational Waves – CalTech

On September 14, 2015 at 5:51am ET, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected ripples in the fabric of spacetime. One hundred years after Albert Einstein predicted the existence of gravit...

Go on a Snowflake Safari

The next time you're going out in the snow, take a magnifying glass with you and see if you can find an elusive 12-sided snowflake... and if you don't happen to see that one, take note of the ones you do find. Is it n...

Frozen Soap Bubbles: Ice crystal ‘snow globes’ by ZALUSKArt

Watch ice crystals form on soap bubbles in -15C, filmed by Warsaw-based photographer and videographer Pablo Zaluska. He was inspired to film these delicate formations after having a conversation with his three year ol...

Circular motion demonstration with a sparkler & a hula hoop

From physics teacher and film maker Alom Shaha, check out these simple demonstrations showing how something moving in a circle will move in a straight line when you remove the centripetal force acting upon that thing....

A robot vehicle that drives on walls using propellers

Drive on the ground, drive on the wall, maybe, just maybe, drive on the ceiling. The result of a collaboration between Disney Research Zurich and ETH Zurich, VertiGo is a four wheel vehicle that appears to defy gravi...

How to grow snowflakes in a bottle – Science Friday

If there's no snow outside, try growing your own snowflakes. From Science Friday's collection of Holiday Science features and experiments, learn how to grow snowflakes in a bottle. Caltech physicist, snowflake expert,...

Zero Gravity 360° + Weightless Water Experiments

Go on a zero gravity parabolic flight, also known as the ‘vomit comet’, in this 360º video from The Royal Institution. Drag the video in any direction using any modern browser or the YouTube mobile app... and, of cour...

How to make simple homopolar motor ‘race cars’

Lay out a 'race track' of tinfoil, attach two round neodymium magnets to the ends of an AA battery x2 (or more) -- the polarity of the magnets matters, so experiment to see how your vehicle behaves (or doesn't) -- the...

How Google[x]’s Project Loon Tests Its Giant Internet Balloons

What if massive pumpkin-shaped balloons could bring internet access to rural and remote locations around the planet? Google[x], which also developed Google Glass and Google's Driverless Car, has a team working on gian...

Why Isn’t It Faster To Fly West? – Minute Physics

When you think about how the Earth rotates -- to the east -- it would seem to make sense that a plane flying west would meet its destination sooner... after all, isn't the planet is spinning toward the plane? In fact,...

How to make a DIY ‘drone’ with balloons & a fishing rod

How do you get a bird's eye view of the surrounding landscape when you don't have an quadcopter or drone? In this episode of Earth Unplugged, Sam Hume cobbles together his own 'drone' for less then £50 (around $76). S...

Emperor Penguins keep warm in an ever-shifting huddle

With brand new baby chicks sheltering in so many of their brood pouches, warmth is imperative for Emperor Penguins in the coldest place on the planet. But how do you stay warm enough to survive in -40 degrees or colde...

The physics of ‘skydiving’ wind tunnel acrobats

In a vertical wind tunnel that's blowing air upward at 270 km/h (168 mph), four 'skydiving' acrobats perform a twisting, turning flying routine without ever colliding into each other. How do they perform epic looking ...
