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.
Inspired in part by a scene in The Dark Knight, maker Coltography decided he wanted a fully-illuminated drop-tile ceiling. While he could have gone with old school fluorescent tubes, he built his system using lots of LED light strips. Those touch-based wall controls he made are really slick.
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.
Electronics geeks would love to have a table like the one that New Yorkshire Workshop made. Watch as the artist painstakingly applies gold leaf to produce jumbo metal circuit board traces on a dyed-blue maple veneer, then gives it a nice shiny clear coat. Watch how he made the twisted “wire” copper legs here.
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.
Now that Buttered Side Down has figured out how to perform magic and play the violin, he’s worked up quite the appetite. To satisfy his hunger, he set about making a pizza in the only way he knows how – with a GoPro strapped to his head. We’ll have to try that pepperoni trick sometime.
The dulcimer usually is associated with the kind of music you’d hear at a renaissance festival. But musician Sam Edelston believes the stringed instrument is “among the world’s coolest.” Listen up as he plays some truly rockin’ cover versions from the Ramones, Black Sabbath, and David Bowie.
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.
We’re surprised that LEGO machine expert JK Brickworks has never built a Great Ball Contraption module before, but his first one definitely lives up to his standards. Watch as four tiny LEGO robots work along an assembly line, each passing a ball to the next to move it down the line. It also appears to work as a hypnosis device.
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.
From 1917 to Joker to Once Upon a Time in Hollywood, the 2020 Academy Awards has some pretty solid contenders. But regardless of how good a movie might be, Screen Junkies is always ready to roast it. So without further ado, enjoy their very special Oscars edition of Honest Trailers.
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.
Do you like sitcoms? Then check out this wonderful medley of theme songs from shows like Friends, Seinfeld, It’s Always Sunny in Philadelphia, The Big Bang Theory, Parks and Rec, and The Office, performed on acoustic guitar by Nathan Mills of Beyond the Guitar.
Photographer Eugene Belsky shows off the kind of incredible close-up images that can be captured with the Venus Laowa 24mm probe lens and a Blackmagic Pocket Cinema Camera 6k. The razor-sharp 4K footage gets intimate with a variety of edibles, and looks even more spectacular if you’ve got a display that supports HDR.
