Once a car is no longer drivable, it heads to the junk yard. But before it ends up on the scrap heap, machines like the Powerhand VRS are used to rip apart the car to separate materials, maximizing recyclability of components. It looks like a great way to work out aggression too.

Inspired by an ancient Chinese myth about creation, Taiko Studios‘ animated short film tells the story of a god who has the ability to conjure worlds from nothing. When he realizes the one thing missing is a child, he makes a son in his own image. But will independent thought drive them apart, or bring them closer together?
(PG-13: Language) Hell is a hell of a place. But what’s the deal with the fiery, demon-filled land of doom? Where did it come from, and why are we so afraid of ending up there? Ordinary Things provides a brief history of the netherworld and why the place has to be so darned unpleasant.
“How do you stop a rhino from charging?” The Slow Mo Guys take on one of their more unusual subjects – the kind of dart used to tranquilize animals. To demonstrate how these unique medicine delivery vessels work, they filled samples with food coloring, then watched the pressurized fluid release as it met its subject.
If you’re going to construct a building, you want to use a tough adhesive to hold things together. In this clip from Russian building materials company Kuvalda, they show off just how impressive Makroflex foam adhesive is at holding bricks together. Though we’re not sure you’d want to stand on that 50 feet up in the air.
Amateur philosopher and space enthusiast exurb1a reminisces about the history of lunar exploration, from the Apollo missions through NASA’s plans to return to the moon in the 21st century. Along the way, you’ll learn a thing or two about the moon’s origins, its relationship to Earth, and more.
We’ve featured lots of wonderful science and education videos from Kurzgesagt over the years. Now learn how they research, plan, script, storyboard, animate, narrate, and assemble their clips. It’s a great watch for fans of the series, or for anyone interested in creating high-quality content.
This flexible bike lock is not only easier to wrap around posts than traditional U-locks, it’s far more durable. It can withstand a tremendous amount of torsion – which can destroy other locks, and has a pick and drill-resistant lock cylinder. It’s also insurance-rated, with optional bike theft coverage available.
Drones can capture amazing imagery, but they can wreak havoc in the wrong hands. To eliminate threats from UAVs, Israeli defense tech company Rafael has created Drone Dome, a system that can jam drone communication or pluck them out of the sky using a laser. It can spot objects as small as 0.02 sq. ft. from 2.1 miles away.
The earth gets pelted by small meteorites on a regular basis, but bigger bits of asteroids breaking through are far less common. MetaBallStudios does their best to give us a sense just how big some of these space rocks can be, standing them besides the skyscrapers of NYC for comparison.
Coolest Thing introduces us to self-proclaimed mad scientist Lance Greathouse. Among his many builds is a motorized wheelchair that packs a flamethrower on its front end. But he doesn’t just build silly stuff, Lance and the folks from the Wheelchair Labs helps refurbish wheelchairs for people in need.
There are professional card throwers out there who can land a playing card on its edge every time. But if you don’t possess those skills, you could always build a mechanical solution, like The Practical Engineer did. His motorized launcher can fire playing cards at speeds nearing 200km/h (or about 124 mph).
For 2021, the already fun to drive Toyota GR Supra 3.0 gets a power bump to 382hp, shaving 2/10ths off its 0-to-60 time, down to 3.9 sec. A 2.0-liter turbo-4 version is also on tap with 255hp and 295 lb-ft. of torque, as well as an A91 special edition with carbon fiber bits, matte black wheels, and a sweet new Refraction Blue paint color.
When an airplane encounters just the right weather conditions, its wingtips and propellers can generate visible patterns in the air. Redditor cburnett shared this wild footage of the patterns made by the four props on a Hercules C-130. A google search for “propeller vortexes” turns up more incredible images of the phenomenon.
You might be freaked out about using plastic straws, but it takes a whole lot of them to have the same environmental impact as producing other things we buy and consume. Casually Explained provides a comparison of various CO2 producers, and thanks the Bill and Melinda Gates Foundation for sponsoring this episode.
Restoration Station got his hands on a beat up old push reel mower his father found, and went through painstaking efforts to remove all of the rust and detritus to make it look as good as new. He says this was one of the more difficult projects he’s worked on due to the blade assembly being a challenge to work with.
We shoot a lot of video inside of cars looking out the windshield. But the in-car footage often makes it look much slower than it felt zooming around the track. After watching this clip from Akiyoshi Kitaoka, we realize just how much of a difference having a wide angle lens makes when it comes to the perception of speed.
In this scene from the Discovery UK show Richard Hammond’s Big, the Hamster visits the Verbund Hydro Power plant in Austria. Watch as he gets up close and personal with the massive stream of water coursing out of the bottom of a hydroelectric dam, where more than 5000 gallons of water gush out per second.
The Hydraulic Press Channel took a momentary break from just smushing things for fun, and instead performed a bit of a physics experiment. By creating multiple 3D printed objects of the same weight and mass, but just different shapes, they were able to evaluate which shapes were the strongest of the bunch.
Ever wonder why we add a day to the end of every fourth February? Well, as it turns out, the Earth orbits the sun every 365.242 days, so we get off by about a quarter day every year. Dr. James O’Donoghue provides a concise graphical explanation of this time tweak we do to make things right, and what would happen without leap years.
As we’ve moved away from print and towards digital reading, highlighters aren’t as popular as they once were. But these fluorescent pens are still pretty cool for making art. Science Channel’s How It’s Made shows the process of molding the plastic bodies, filling their nibs with ink, and testing them for smooth flow.
Want to keep neighborhood rugrats off your lawn? Minutephysics and Randall Munroe of xkcd have got you covered, with their step-by-step plan for installing a moat filled with molten hot lava. Sadly, it would cost about $60,000 a day to keep it running unless you dig down deep enough and power it with geothermal energy.
Over the years, we’ve broken at least a couple of those oscillating fans, but could never figure out how to fix them. Jared Owen’s insightful 3D animation could have been a big help, as he shows us exactly how its mechanisms work to keep it moving from side to side.
While many considered Nikolai Tesla to be a genius, he also had some pretty outlandish ideas, like the notion that we would stop drinking coffee by the 21st century. Mental Floss editor Erin McCarthy explores this and a number of other wacky predictions that have yet to come true, among them, undersea buses propelled by whales.
