# What Dark Magic Makes This Weird Yo-Yo Work?

Yo-yo tricks are already a miracle of physics. But Ben Conde specializes in a type of yo-yo with an unattached string, and does things that defy all logic. But there’s one sneaky feature that makes these contraptions work.

# Cool View of a Pilot Pouring Water Upside Down While Doing a Barrel Roll in a Fighter Jet

It’s always fun to melt your brain from what looks like the laws of physics breaking. Therefore, it’s always fun to see a pilot pour water up into a cup while upside down in a fighter jet. It’s something we’ve seen plenty before, but this view is especially cool. You get to see the entire process happen so clearly:…

# Alton Brown Makes a Gallon of Carbonated Ice Cream in 10 Seconds Flat

Alton Brown has been the world’s preeminent food science wizard since the early days of the Food Network, and he’s about to embark on his second tour. What better way to celebrate than with a big vat of ice cream?

# How Ballerinas Can Keep Spinning Forever

The third act of Swan Lake is considered one of the most difficult in the balletic cannon, requiring a dancer to twirl around 32 consecutive times. How its accomplished is as much a feat of physics as it is athleticism.

# Slowing Down In Space Is Easier With Yo-Yos

Any number of forces can mess up a spacecraft’s flight path on its way to where it needs to go—but spinning helps average those torques to add stability to the trajectory. But when a satellite does successfully reaches orbit, how does it stop spinning?

# Cute Animation Explains Newton's Laws of Motion

Do you remember Newton’s laws of motion? Something something apple, right? No! Something something force equals mass times acceleration? That’s more like it. That’s only the second law, there are two others laws of motion that you’ll find out in the video below. The animation to Mars is neat enough to watch even if…

# Almost Getting Smashed By a Swinging Wrecking Ball to Prove a Law of Physics Is Crazy

Our favorite physicist Andrea Wahl is back with his wild experiments where he blends real life physics with Jackass-style self torture. This time he uses a swinging wrecking ball to prove how conservation of energy can neither be created or destroyed, it transforms into other forms. Basically, as dangerous as being in…

# Video Shows How a Bullet Fired Underwater Doesn't Shoot That Far

No one should ever have to face the other end of a gun barrel but if you manage to find yourself in such a situation, let’s all hope that it’s underwater. Here’s our favorite physicist Andreas Wahl proving how the velocity of a bullet slows down like crazy when it’s fired underwater with a lovely visual experiment.…

# Mixing Glow Sticks with Ferrofluid and Magnets Basically Breaks the Visible Spectrum

We know the chilling magic that is using magnets to control ferrofluid, it’s the closest thing we have to the black arts. But when you add the the chemicals inside a glow stick to the mix, it becomes something so visually awesome that you feel like you’re seeing things move and pop and react in ways and color…

# Watching These Tops Spin Forever Breaks My Understanding of Reality

These tops can spin for nearly 20 minutes long. That was not a typo. The one on the left spun around for 18 minutes and 56 seconds while the one on the right duked it out for 17 minutes and 55 seconds. And even though machines were used to initiate the top spin, the force of the spin is equal to that of a normal…

# Crazy Falling Man on a Loose Rope Stunt Shows How Physics Works

Here’s the idea: A man is going to be attached to a rope and then fall. The rope is totally loose and not attached to anything but there will be a weight rigged to the opposite end of the rope (the other end holds the man, remember). What happens? Does the man fall straight down? Nope! The rope swings around and…

# Space makes things that are spinning act completely crazy

Being in zero gravity has to be a never ending amount of fun. Everything that you boringly do in your normal life, all the things you don’t bother to look twice at—they all become instantly more interesting because you have no idea what’s going to happen. Just check this spinning T-handle in zero gravity, it spins one…

# New Test Suggests NASA's "Impossible" EM Drive Will Work In Space

Last year, NASA’s advanced propulsion research wing made headlines by announcing the successful test of a physics-defying electromagnetic drive, or EM drive. Now, this futuristic engine, which could in theory propel objects to near-relativistic speeds, has been shown to work inside a space-like vacuum.

# First Ever Image to Show Light as a Wave and Particle at the Same Time

What you're looking at here is a major breakthrough. The image reveals a property of light that has never been witnessed before by human eyes, though we've long known about it. But at last, thanks in an ingenious imaging experiment, we can now see how light behaves as a wave and a particle at the same time.

# How small is an atom, really? (or how to make your head explode)

Kurzgesagt has a neat new explainer: "How small is an atom?" I watched it. It does a great job at giving you an idea of how small atoms are and how they work. But it doesn't matter, because my brain just plainly refuses to believe any of this. Hulk head hurt. Hulk smash atoms. Oops, Hulk make nuclear detonation.

# Mystery solved: Why raw spaghetti always snaps in more than two pieces

Smarter Every Day has found out a solution to a mystery that even a Nobel Prize in Physics like Richard Feynman couldn't solve: Why spaghetti never breaks in half, but in three or four parts. To find out he filmed the break at 250,000 frames per second—it's a fascinating answer to a question I never had.

# Can Santa Claus exist according to the laws of physics?

I love this cool visualization of Santa Claus' Christmas Eve trip as seen from space but, with the current laws of physics, we know he wouldn't be able do it. Or would he? Can Santa be real and deliver on his promises? The question is tricky, as this scientific debate shows. Let the classic scientific fight begin once…

# Why is the speed of darkness faster than the speed of light?

Michael Stevens explains why darkness moves faster than light in this new episode of Vsauce. I usually find these explainers interesting because they delve not only into multiple science disciplines but often they touch philosophical questions too. This one really blew my mind.

# Scientists think there may be a wormhole in the center of our galaxy

If Zilong Li and Cosimo Bambi of the Fudan University in Shanghai are correct, what we thought was a massive blackhole in the center of our galaxy could be a wormhole that would allow instantaneous travel between two points in space and time. In fact, it may be the gateway to a different universe.

# Hilarious slow-motion video turns Neil deGrasse Tyson into a stoner

Astrophysicist and Cosmos host Neil deGrasse Tyson, in addition to being a general badass, is most famous for his wildly infectious exuberance for all things science. Unless, of course, NDT is stoned out of his mind. In which case, that vigor would probably turn into the masterpiece you see below.
