The video is older, but it turned up recently in a really interesting blog post by Kyle Hill that does a fantastic job of explaining how superconductors work — and why you can create a floating skateboard, but you're stuck using it in conjunction with a track.
Instead of putting a magnet above a superconductor, you can put a special kind of superconductor above a magnet and “pin” it in space. Type type-II superconductors, like the one featured in this now viral “quantum locking” video, are superconductors that also expel magnetic fields from their innards, but not perfectly. These superconductors are thin enough for flaws in the material to allow small “flux tubes” or “quantum vortexes” to leak through. When that happens, it’s like suspending a pincushion on a bed of nails—the superconductor is locked in space.
More than 800 American energy and Earth science researchers have signed a letter to Donald Trump outlining six steps they’re urging him to take to address human-caused climate change to protect “America’s economy, national security, and public health and safety.” The letter is accompanied by a public change.org petition to “Tell Trump To #ActOnClimate.” Here […]
James Delingpole is an invective-hurling anti-climate science columnist who has candidly admitted that he doesn’t bother to read scientific papers, calling himself a “an interpreter of interpretations.”
Kratom (previously) is a widely used herb that has been very effective in treating opioid withdrawal and other chronic, hard-to-treat conditions — it also became very controversial this year because the DEA decided, without evidence, to class it as a dangerous drug, and then changed its mind (unprecedented!) after a mass-scale petition that included interventions […]

Unlike traditional lighters, the SaberLight features an electronic plasma beam that’s both rechargeable and butane-free. This sleek lighter is even approved by TSA, so you’ll never be stuck buying lighters you’ll just have to throw away partially used. For some people, like me, this is a pretty big game-changer. The SaberLight’s beam is actually both hotter and cleaner […]
