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.
Smarter Every Day talks about the Prince Rupert’s Drop. Made of molten glass that’s been dripped into cold water, its thick end is very durable, but the slightest of cracks on its tail end causes it to explode.
Engineers at the University of Maryland are working on a massive, lightweight copter which can lift 10 feet off the ground, entirely on the power of a single pilot – with eyes on the elusive Sikorsky prize.
