Metallurgist Grigory Raykhtsaum shows Smithsonian three different ways to test if something is solid gold: a color test, a thermal conductivity test, and a particle test. It’s all computerized now so all he has to do is scan the object to get a read on the color, zap it with an electrical current to measure the…
Any flab? Any extra skin? Anything that’s remotely loose on your body, it looks like it’s mere seconds from flying away and detaching from the rest of you when you try to withstand 457 mph of wind on your face. Here’s a video showing a test conducted in 1946 where a human subject was exposed to blasts of air that…
300 miles north of Vancouver lies the Great Bear Rainforest. It’s a huge, rugged, chunk of land with ample diversity of scenery, and the best part is that it is very, very sparsely populated. Think Yellowstone minus the tourists. In a nutshell, you want to go to there.
Atom Central recently published these four unreleased videos of atomic bomb testing in 1955. The footage, taken from Operation Teapot at the test site in Nevada, is in glorious HD so it’s pretty incredible but watch out for the blinding light. Even in a small little YouTube window, it hurts.
Here’s really awesome footage that shows a B-52 bombing run on an island from inside the weapons bay. You can see the open doors of the plane peering down towards the ocean and then see the bombs drop away and strike the target and pepper the ground with explosions. Such a cool perspective.
The problem is simple enough. You’ve got a raw egg, and it’s going to be dropped from a high place. You have to build a contraption so that it doesn’t break when it hits. Easy? Maybe. But how do you make it as light as possible? Or as small as possible?
This new BioLite NanoGrid functions as a hanging work light or lantern, a multi-point area light, a powerful flashlight and a portable power source for your electronics, all in a single $100 product. The ultimate camping gadget? I got my hands on a unit to find out.
Thanks to its shoe-style, zipper-free design, this new Backcountry Bed Duo from Sierra Designs packs bed-level comfort for two into a bag that's small and light enough to actually fit in a backpack. If you want to cuddle outside, this is the bag for you. Sadly, it's not as good as it could be.
You know how people call every kind of facial tissue "Kleenex," even if it's technically from another brand? These days, GoPro is practically synonymous with action cameras. I can't use any other action cam without someone asking me, "Is that a GoPro?" But there's a damn good reason why GoPro is on top of the world.
Impressive video of a new Norwegian Naval Strike Missile tested off the coat of Andøya, in northern Norway: The 400-pound, four-meter-long, 150-kilometer-range weapon hit and blew up the frigate KNM Trondheim.
Sure, Apple's only received nine reports of bent iPhones and we highly doubt you'll have any reason to worry about your own, but do Apple's new iPhone 6 and iPhone 6 Plus handle the pressure any better than competing models? Consumer Reports put that to the test, pitting the new iPhones against other giant…
The last time we saw an action-camera come out of Contour, it was for the Contour+2. Image quality was pretty good, but the mounts were way too fragile, and under the shadow of GoPro's colossal market-share, Contour shuttered its doors. But now it's back! And its first product back is... a slight improvement on its…
As things get hotter between Russia and NATO, Putin is waving his nuclear dick around. Russia plans to conduct massive nuclear war maneuvers. Yesterday it successfully tested its new Bulava ("Mace") submarine launched nuclear missile, hitting its target with complete accuracy with its dummy warheads.
This looks like a scene from a sci-fi game or movie, but it's actually a photo from one of the latest tests of the X-47B unmanned combat aircraft on board the USS Theodore Roosevelt. The US Navy is getting really close to the future, people: Combat drones launched automatically from motherships.
I love it when animals can solve puzzles and problems that I can't even figure out. Here's a crow going through a bunch of different exercises to show its understanding of size, weight, density, the elements and even the amount of effort it should put in to a puzzle to win its reward.
NASA is sending new and bigger spaceships to Mars, which means they need bigger supersonic parachutes. So big, in fact, that they don't fit in any wind tunnel anymore, so their engineers had to find new ways to test them. New crazy ways. Really crazy. In fact, it's the craziest test they got so far.
Would you know Reddit or Twitter if you were only looking at their layouts? You might not think so—but you'd be surprised how well you know the structure of your most-used sites. Now, you can take a test to find out.
Kaboom. And fireball. And ground shake. And shockwave. And boom. AtomCentral shows us some amazingly clear HD footage restored from 1953 of the Atomic Cannon test from Upshot-Knothole Grable. In the video below, you can see cars, jeeps, buses and tanks against the backdrop of the ginormous blast's initial burst and…
