There's a hard speed limit for helicopters. Like, a speed that helicopters physically can't exceed. Above about 400km/h, helicopter blades literally run out of lift and the bird falls out of the sky. It's due to a phenomenon called dissymmetry of lift, and this video explains exactly how it works.

If you've got an iPhone, stay wary of any suspicious links that your friends or enemies might send you any time soon. YouTube, Vimeo and other reputable video hosting services are perfectly safe, but there's one particular video link doing the rounds at the moment that can lock up your iPhone and require a hard reboot.
Video: The grim dark future of the 41st century needs a weapon as ludicrously gritty as the setting of Warhammer 40,000 — and the chainsword, standard melee weapon of the hulking Space Marines, definitely fits the bill. But now such a silly weapon has been made in our reality, and it's just as awesome.
Video: Watch it on a big, high-resolution screen and 4K video looks awesome. 12K video is even more incredible — even though we don't have screens that can show it off to its full potential yet — because it means you're able to zoom in to a tiny portion of the frame and still see perfect detail. Shot by Joe Capra of Scientifantastic, this 100-megapixel time-lapse of Los Angeles, shot on a camera worth more than $100,000, shows just how amazing high-res video can be.
Video: Ben Ridgway's specialty is creating flawlessly repeating animations that can be left on loop forever if you're trying to intentionally trigger the worst acid flashback you've ever experienced — minus the acid. Continuum Infinitum has no beginning and no end, just an infinite zoom into a never-ending abyss of trippy mind-melting shapes.
Video: I swear it was an accident. For two weeks, I flew the DJI Phantom 4 as often as possible, to learn about its quirky but impressive feature set. When it came time for the final test — seeing how obstacle avoidance worked at high speeds — it slipped my mind that the technology doesn't work at all at high speeds.
For the past four years, filmmaker Joe Nafis has been chronicling the construction of the Shanghai Tower. After 1,000 work hours and 350,000 photos, he's put together a stunning timelapse video that you don't want to miss.
YouTube's attempt to break into the original content game isn't anything revolutionary. In fact, you could say that they're late to the party Hulu, Amazon and Netflix are throwing. And in some desperate attempt to fit in, they have taken view counts off of YouTube Red shows.
Video: There's all sorts of expensive R&D facilities working frantically to make body-enhancing skeletons into actual things, but the research isn't limited just to big companies. Two years ago, a YouTuber showed off his Elysium-inspired suit curling 77kg; last weekend, he decided to lift a Mini Cooper.
