It’s called the Schlieren effect and it means that you can see stuff that’s invisible to the human eye, like changes in air density. So when you turn on a hair dryer, you can see the blast of air it shoots out. When you open a can of Coke, you can see what’s escaping into the air. When you rub your hands, you can see…
I could tell you that this hay floating in the air and spinning around in a circle is a result of a dust devil, where hot air rises up through a small pocket of cooler, low-pressure air above it (kind of like a harmless mini-tornado). Or I could tell you that it’s obviously dark magic at work and the dust devil is…
You’ve probably heard that the new movie 10 Cloverfield Lane started out as an unrelated thriller called The Cellar (or Valencia). And then producer J.J. Abrams decided to rename it 10 Cloverfield Lane, and make it a “sister movie” to his 2008 sleeper hit. This was probably a mistake, because it underscores that this…
Kaboom! It’s no surprise that a basketball would explode if you pumped it with a ridiculous amount of air but it’s really cool to see it unravel in super slow motion. The ball basically disintegrates and you can see the limp leftovers tear apart from each other as the orange sphere separates from having too much air…
Norman Reedus volunteers to test out a cryogenic suspension chamber—only to find out that it’s not just like going to sleep regularly—in this clip from the new movie Air. This is one of the most terrifying moments in this post-apocalyptic movie, and we’re presenting it exclusively at io9. This moment made me lose my…
Darryl Dixon isn’t even in the Walking Dead comics—but he’s become such a beloved character on the TV show that tons of people wear T-shirts threatening to riot if he’s killed. We asked actor Norman Reedus what it is about Darryl that makes him so beloved.
For years Apple's MacBook Air has languished in partial obsolescence—a great laptop with fantastic battery life and a quizzically outdated screen. 1440 x 900 is a pitifully small resolution for modern times. Sadly, the company hasn't learned its lesson: the 2015 MacBook Air refresh has the same, outdated display as it…
We can feel the wind when it hits us and we can track wind patterns when we check the weather and when it's really strong, we can totally see the effect wind has on the world around us but this video let's us imagine what seeing actual wind would look like. It looks like ghosts. Now I'm glad we can't see the wind.
You can have your graphene or your insane non-flammable fabric or some NASA space material, magic material to me will always be bubble wrap. It's catnip for humans with souls and the process to make it is pretty fascinating. It starts with resin that is vacuumed out and heated to create a film and used to trap air.
Meet Brian Jackson, an 11-time Guinness World Record holder who's probably a mutant with the lungs of a giant. He can make those red hot water rubber bottles explode in 51.98 seconds. Those bottles need 170 pounds of pressure to blow up so yeah, Jackson's breath is basically superhuman.
Produced by The Walking Dead's Robert Kirkman, Air stars TWD's Norman Reedus and Djimon Hounsou as maintenance workers in a silo containing the remnants of cryogenically frozen humanity after the air turns poison. As this first trailer reveals, something goes wrong, and the two workers have to fix it... fast.
We've seen this stunt before: a daredevil with nerves of steel and absolutely zero fear of heights walks a slackline strung between two hot air balloons. But until today, we'd never seen it from the walker's-eye view. Deep breaths. Deep, terrified breaths.
Billboards of the world, you can aspire to be more than signs pointing to cheap motels and sleazy roadside attractions. An engineering team in Peru has created a billboard that they say can purify 100,000 cubic meters of air everyday—taking in pollution and spewing out sweet, fresh air for the city.
Irwindale, California, home of the sriracha factory, has declared the factory where that particular bit of hot sauce-alchemy happens to be a public nuisance. No, not to other, lesser condiments (hi there, ketchup), but to the air.
Everyone's favorite Walking Dead character is getting his own personal apocalypse movie. Set in an underground facility isolated from the destroyed future Earth, Norman Reedus is the caretaker for the only survivors left on the planet, who all happen to be frozen.
Shenzhen and Hong Kong are two major economic powerhouses just twenty miles apart. Thousands of cars and people cross their borders every day. But their close relationship belies inequalities that still exist between the city of Shenzhen and the Special Administrative Region of Hong Kong.
What happens if you take 500,000 pieces of Lego and 256 pistons, then hand them over to Steve Sammartino and Raul Oaida? This fully functioning, life-size, air-powered Lego car is what.
So there's Windex, but if that's feeling too cleaning product-y for you, be aware that you can also clean glass with pure oxygen plasma. Sure.
Money doesn't grow on trees. You can't get something for nothing. There's no such thing as a free lunch. Except all of these cliches are apparently false, because Antoine Deblay, a student who lives in southwest France is actually making money selling cans of air from his town.
I've seen Earth compared to all its water before, but this image really gives you a perfect idea on how fragile our planet is by adding all the air in another sphere. The density of the air pictured here corresponds to its density at sea level (one atmosphere.)
