This Guy Can Control Water By Shooting Vortexes With His Mouth

It looks so effortless for him. And not only can freediver David Helderle blow underwater bubble rings as easily as you and I blink, he can control those mini vortexes to make fun designs and spin rings. It’s like Aquaman decided to become an artist or something.

This Turquoise Gem Is What Summer Looks Like In Southeastern Alaska

Briefly: This turquoise gem is what summer looks like in southeastern Alaska. From an altitude twice that of commercial jets, NASA’s arctic research aeroplane ER-2 — a civilian version of the Air Force’s U2-S reconnaissance plane — captured this view of a summertime melt pond atop a glacier on July 16, 2014.

Giant Goliath Fish Punks A Fisherman And Then Steals His Fish And Gun

Video: This goliath grouper sure isn’t happy about sharing the waters with us humans. It grumpily swims over to the man spearfishing, intimidates him with a little head butt and then steals the fish he caught. Even worse, he took the guy’s gun for a little joy ride. It’s like stealing someone’s date right in front of them.

Watch Guys Do Push-Ups On The Surface Of The Water

We don’t run fast enough to walk on water, but aeroplanes and boats can whip us along at speeds so fast that we can ski barefoot and even do fun workout tricks like push ups without sinking. Yeah. After seeing these guys do push ups on the surface of the water, walking on water is so passé.

Watch Water Doing Crazy Stuff On Hydrophobic Surfaces

Video: There are a lot of great applications for materials being developed that display extreme water repelling properties, inspired by nature and particularly desert life. This video doesn’t explain any of them and that’s fine — I just like to watch all those crazy water droplets doing crazy stuff.

This Machine Generates Electricity From Humidity

This silver cube looks like it belongs on a spaceship — but actually it’s way more exciting than that. In fact, it can create electricity from humidity, as water condenses on its internal surfaces.

The Surprising Science In A Single Drop Of Regular Ol' Tap Water

Tap water: we drink it, we bathe in it, we wash our clothes and dishes with it, and we cook with it. We probably take it for granted. But delivering clean, safe water to every kitchen and bathroom in the country is no easy task, as Wired explains in this eye-opening little explanation into the secret life of tap water.

Why Is Some Ice Clear And Some Cloudy?

Unless you happen to have a specialised ice machine in your home, it is practically guaranteed that the ice your freezer makes is of the cloudy variety. A popular and well-known trick to making clear(er) ice is to either boil the water first or use distilled water. However, even doing this won’t guarantee the kind of perfectly clear ice you’d find in a high-end bar or restaurant. This is because how clear ice is, is only partially dependent on the purity of the water you use, meaning even if you managed to procure the tears of a Saint and pass them through the world’s best water filter, you’d still likely end up with ice that was a little cloudy.

This Is Why You Should Only Drink Water With Impurities

Video: It may sound like a good idea to drink the purest water you can find, but as this video explains, that is not actually the case. Ultra pure water has no impurities — so absolutely no taste — but also in large quantities it will harm and even kill you, because it will leech the minerals from your body.

There Are Vast Reserves Of Ancient Freshwater Hidden Below The Ocean

When you’re drilling deep under the seabed, the last thing you might expect is freshwater. Yet Danish scientists on a recent expedition in the Baltic Sea suddenly found freshwater gushing up from their drill. In fact, undersea freshwater reserves are hidden all over the world, and some claim this could quench our thirst for decades to come.
