Students from the University of Minnesota captured raindrops hitting sand at various velocities using a high-speed camera. Apparently the craters left behind by the drops are similar to those made by asteroid impacts.
Michael Stevens explores the antiquated and crackpot theories that the Earth isn’t round, and demonstrates the science of what would happen to us if our planet were really flat. On the other hand, we still believe time is a flat circle.
While some model railroads can be incredibly complicated, this one is constructed from nothing more than a copper wire, tiny magnets and a dry cell battery. We wonder how big a track you could make using this method.
In this fascinating clip from BBC Two series Human Universe, they demonstrate how a bowling ball and feather fall at exactly the same speed when air has been almost completely removed from a giant vacuum chamber.
Need the Cliffs’ Notes for the physics lesson where they explained the difference between matter and antimatter? Minute Physics does their best to sum up this perplexing science at their usual rapid-fire pace.
While the “hot ice” shown in this video isn’t really ice, it’s still a trippy chemical reaction created when a liquified form of sodium acetate trihydrate comes in contact with the solid form of itself, creating ice-like crystals.
A neat trick that makes clear objects dipped into liquid appear to have vanished. The secret – using glycerol or another clear, viscous liquid with the same refractive index as the outer glassware. Yeah, science!
Nitinol is an alloy made from nickel and titanium that can regain its original shape when heated. In this clip from science geek MIST8K, he shows off the material’s amazing properties. Also, we just added the word “scrumpled” to our dictionary.
Illusion hitmaker Brusspup shows off a magnetic device which can actually make objects hover. We’ve seen a smaller version before, but his use of large objects, and concealing the magnet makes the effect much more impressive.
To infinity and beyond! Veritasium’s Derek Muller looks at the nature of our ever-expanding universe, how space itself moves faster than the speed of light, and how the universe is dramatically larger in light years than its age.
Unless you want to lose, you never want to try and remove a single block at the bottom of a stack of Jenga blocks. But this guy exploited the laws of physics to help him pluck out the bar without toppling the whole tower.
The music video for first track from Jack White’s upcoming solo album Lazaretto – an instrumental that combines blues and intense electric riffs, set against the backdrop of non-newtonian fluids and sand vibrating to the track’s frequencies.
YouTuber spumwack uses the simple graphics and programmable physics of Minecraft to better explain some of the complicated concepts of light speed. Like any good physics video he takes time to make us feel incredibly insignificant too.
Derek Muller from Veritasium show off how you can easily lift a 42 pound weight at the end of a metal rod, thanks to the wonders of gyroscopic precession. If only everything we ever had to lift was spinning at 2500 RPM. More here.
A fascinating look at the Leidenfrost effect, in which heated water droplets move towards each other and coalesce, as well as scenarios in which water droplets can actually climb uphill, or even be self-propelled along a pre-arranged path.
This brief demonstration of Lenz’s law shows how the magnetic field created by currents in this large copper tube resists the magnetic field of a falling neodymium magnet, causing it to drop in what seems like slow motion.
Scientists have uncovered some fascinating behaviors of ant colonies. When poured through a funnel, they act as a liquid, moving around each other – but when picked up or pushed down they become a sort of solid, clinging to each other.
Professor Dan Burns uses a sheet of spandex, some bearings, marbles and weights to demonstrate the basic principles of gravity, and how planetary orbits were established. It’s how to play with the fabric of space, literally.
BBC Sport explains how downforce and the aerodynamic design of Formula 1 cars not only help them tear through tracks but also make them capable of driving upside down. So… why aren’t F1 cars racing upside down yet again?
YouTube experimenter Tao Fledermaus decided to see what would happen if you submerge a sponge in mercury. The ensuing demo shows the impressive surface tension encountered when dipping a foreign object in the liquid metal.
One of the biggest risks boats face is capsizing from large waves. Check out this amazing technology which creates inverse waves inside the boat to keep it from rocking. The boat model on the left has the system in place.
A reboot of Carl Sagan’s classic series, this epic 14-part documentary stars astrophysics badass Neil deGrasse Tyson – and is produced, surprisingly, by Seth MacFarlane. Coming to FOX in 2014. (Thanks, Wille from Feber!)
We’ve seen a hovering superconductors before, but this nifty neodymium magnet-covered track propels a floating vehicle along a looped surface, infinitely twisting upon itself, the vehicle floating both above and below the track.
It’s been a while since we’ve heard from experimenter Brusspup. Here, he not only shows off the nifty effect of vibrations on sand, but that he’s a musician – having created the ethereal backing track, Dark Wave.
You may be familiar with the practice of strapping propellants to household objects and placing NPCs in/on them in HL2 physics sandbox Garry’s Mod. If not, this video by Brandon J. La might not make much sense. Or maybe it will.
Chris Hadfield may already have returned to Earth, but before he left the ISS, Jamie Hyneman and Adam Savage designed a zero-G game for the astronauts for their rare bit of downtime. Care for a round of Space Darts?
If you’ve ever wondered just how sturdy the concrete pillars made to hold up buildings are, watch this video, in which University of Illinois engineers apply over a million pounds of pressure directly to a concrete cylinder.
