Why Is Some Ice Clear and Some Cloudy?

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… » 7/03/14 5:20pm 7/03/14 5:20pm

Why do ice cubes crack when you drop them in drinks?

The sound of summer is ice cracking as you pour yourself a cold drink. Hearing that snap and pop cools everybody down. But why does ice crack? Periodic Videos explains the reason why ice straight from freezer suffers that sudden crack versus how ice left on a tray will just melt instead of crack. » 7/02/14 12:47am 7/02/14 12:47am

Here's what it's like to plummet down the world's tallest water slide

POV footage shows it's a helluva drop so yeah, it's scary. People will pretty much plummet straight down a 168-foot 7-inch tall slide—which makes it the world's tallest water slide—at thigh burning speeds to blast over a massive hill to ride another "mini" 50 feet slide. It doesn't get any sicker than this. » 6/30/14 9:00pm 6/30/14 9:00pm

How to Grow Food in the Middle of a Desert Using Seawater

As conventional sources of clean water dry up, we're looking ever farther, wider, and deeper. In a long feature on unusual sources of water, Nature leads us somewhere especially unexpected—into the middle of a desert. The Sahara Forest Project wants to prove we can green the desert, turning barren land into oases of… » 6/17/14 8:20pm 6/17/14 8:20pm

This Giant "Straw" Will Suck Vegas's Water From the Desert

Las Vegas gets 90 percent of its water from Lake Mead, the lake created by the Hoover Dam about 45 miles away. It's also a lake that's only half full—with water levels that are decreasing every year. Now the city must dig a massive tunnel that will dip deeper into the lake to ensure Las Vegas's water supply doesn't… » 6/12/14 6:40pm 6/12/14 6:40pm

The Planet's Biggest Water Supply Might Be Hidden 400 Miles Below the US

When most of us imagine what the mantle of the Earth is like, we see burning hot rock and magma (and maybe satan hanging out for good measure or something). But scientists have discovered evidence that all that rock may be hiding huge amounts of water—three times the volume of all our oceans combined. » 6/12/14 3:50pm 6/12/14 3:50pm

Wire magically untangles itself in water

Nitinol wire, a metal alloy made from nickel and titanium, basically has magic properties that lets it remember its 'original' shape. You can bend it over and over, twist it up, bunch it together and confuse the heck out of it however much you want but once you throw it in hot water, it'll snap back to its original… » 6/10/14 11:14pm 6/10/14 11:14pm

The Cutting-Edge Tech That Will Finally Bring Desalination to the U.S.

In case you haven't heard, California is screwed. The drought has turned our perennially water-challenged state into a desiccated husk. In these dire times, we look toward desalination, an idea long-promised but never quite delivered in the U.S. But a spate of new technologies—graphene, solar mirrors, and more—could… » 6/03/14 6:40pm 6/03/14 6:40pm

How the Colorado River Finally Reached the Sea Again

This week, for the first time in decades, the Colorado River flowed to its natural end in the Gulf of California. But it was the opposite of a natural event. The artificially engineered "pulse flow" that pushed the waters all the way to the Gulf required an unprecedented collaboration between the U.S. and Mexico,… » 5/20/14 12:20pm 5/20/14 12:20pm

You Can Boil Water in Paper Cups, Just Like the Neanderthals May Have

Boiling water is as easy as they say—even without pots and pans. Thanks to the laws of physics, you can put a flame up to a paper cup or plastic bag, and water will boil without scorching the container. A paleontologist is speculating that Neanderthals cooked their meat in birch bark trays or skin bags using the same… » 5/01/14 3:00pm 5/01/14 3:00pm
