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.
THE BEST Etc
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.
When you pop open a bottle of wine, it’s easy to forget that its stopper comes from a tree. This footage captured by oenophile Jamie Goode at Portugal’s Cork Supply shows us the labor that goes into cutting pieces of cork tree bark, and punching out individual pieces. We wonder what they do with the leftover bark.
It might have a funny name, but Screwpop’s Inkbiner is a smart little thing to hang from your bag or belt loop. The carabiner-style clip’s main feature is a small pen hidden off of its screw-off cap. The pen takes 2.75″ universal refills, and the aluminum and zinc alloy gadget also doubles as a bottle opener.
(PG-13: Language) “The irritating screech of a dial-up connection was replaced by the equally grating sound of teenagers expressing themselves.” Ordinary Things turns into Ordinary People, as our host walks us through a history of the Emo movement, as it evolved out of punk into something more suburban, then imploded.
Researchers from The University of Vermont and Tufts University have created tiny “xenobots,” which use living cells manipulated to perform tasks. AI algorithms guided the microsurgery used to create these organic machines which could someday clean microplastics from oceans, or repair organs in our bodies.
Don’t end up in the doghouse this Valentine’s Day. Instead, grab your sweetheart a bouquet from Florists.com and get $40 worth of flowers for just $20 when you drop by The Awesomer Shop. They have a huge variety of flowers, plants, fruit bouquets, and gift baskets, and even offer same-day delivery (for an added fee.)
It might take us just a second to chomp down a single slice of banana, but it takes quite a bit longer for ants to dine on such a treat. In this clip from Temponaut Timelapse, see how an army of ants gradually dismantles a bit of banana over the course of two days. Look away if you’re squeamish about bugs.
“I planted more trees in the city of Baltimore than anybody in the history of the city…” Filmmakers Jonathan Bregel & Steve Hoover of Friendzone introduce us to a truly unique man – the retired Principal City Planner of Baltimore who, after years of working for the city, decided to cover himself head-to-toe with a blue tattoo.
Give your iPhone videos a cinematic look with FusionLens 2.0. This clip-on lens can shoot 23:9 anamorphic images, 8mm wide angle, and 210º fisheye shots. Its dual-lens covers both the front and rear cameras for 180º selfie shots, and stitching together 360º panoramas. Available for iPhone X/XS/XS Max, XR, 11, and 11 Pro/Pro Max.
Reigarw Comparisons already showed us the chances of winning big and how we might perish. Now they’re back to explore just how unlikely it is that you’d possess one of the many real-world “superpowers” that our genes can bestow us with. Now imagine how slim the odds are of having multiple mutations.
