Kyle Hill from Nerdist recently posted a brief clip that shows the crazy stuff that happens when you inject compressed air into a bed filled with sand. We spotted this 2012 video from The Royal Institution that shows much more, and provides an explanation of the physics at work.
Sight, smell, touch, taste, hearing. We’ve had it engrained our whole lives that those are THE five human senses, but there are many other things we can detect that don’t tie to an obvious sensory organ. Vox delves into some of our abilities which didn’t make the short list.
It’s the stuff of science fiction at this point, but it’s certainly worth exploring the idea that building a planet capable of supporting human life could be an alternative to colonizing an existing, less hospitable planet. Life Noggin ponders this question in this all-too-short video.
SciShow host Hank Green answers the question none of us were asking, as he explores the rather ludicrous sounding idea of sending our garbage to the nearest volcano, and then just dumping it in. We don’t really need to explain why this is a bad idea, do we?
Lots of us stayed outside to watch the big solar eclipse this week, but this isn’t the view any of us saw. Instead of looking up at the skies, the University of Wisconsin Madison time-lapsed weather satellite imagery to track the shadow of the moon as it crossed the US.
The Backyard Scientist can’t be bothered to cook the meals he got from Blue Apron using normal kitchen appliances. Instead, he turns to more dangerous methods, like a powerful arc flashlight, a high-voltage transformer, a blowtorch, and delicious manganese heptoxide.
Back in 1952, London, England was engulfed in a think blanket of smog that was so nasty that it caused the city to come to a halt, and actually ended up killing an estimated 12,000 people. SciShow looks back at this tragic result of industrial development without controls.
Students from the Ithaca College Low Temperature Physics Lab created a neat version of a quantum levitation track. It still uses supercooling and magnets to work its magic, but adds a fun (and literal) twist to by running its course around a triple-twist Möbius Strip.
Veritasium takes a look at a neat physical property – the ability to levitate a lightweight ball or disc atop a jet of water. The trick involves getting the water to flow along one side, runs up and over the object, creating a state of equilibrium which allows it to spin.
If you thought the expressions beatboxers make while producing sounds were weird, wait till you get a load of this. Tom Thum allowed a doctor to place an endoscopic camera with a view of his throat while he beatboxed. The video is equal parts fascinating and disgusting.
The Action Lab shows off a cool property of polyethylene glycol, a chemical with a crazy high molecular weight. As a result, they stick together in very long chains, so once he pours out a little bit of the liquid, the rest follows on its own, much like metal beads do.
The process of sandwiching oil and ferrofluid between sheets of glass is messy to say the least, but the result is amazing – the ability actually view the radiating fields created by magnets placed on the surface of the glass. Magnetic Games shows us how its done.
Ideally, you’ll strap on a VR headset for this, but if you don’t have one, you can still appreciate the ethereal fractal journey that Julius Horsthuis has laid before you, accompanied by excerpts from one of evolutionary biologist Richard Dawkins‘ most profound lectures.
