Some eerily beautiful fluid dynamics in the form of slow-mo water balloons. They don’t break, and the rebound is sometimes even cooler than the initial impact.

A beautiful map of the world’s rivers by National Geographic. It’s astounding to think that all of that only equates to less than 1% of the Earth’s water.

However, regardless of how much it appears to be, there are a whole lot of living things depending on it. Of them, only one is actively poisoning it for the rest of the biosphere and only one has the ability to clean it up. 

As we advance technologically our methods for fixing it are becoming more effective and less intrusive. At the same time, the amount of pollution being dumped is increasing also. 

While it would be great to develop a viable desalinization process, it’s not something we can count on any time soon. In the meantime, there are a diverse number of things you can do to help. Recycle, live more green, and use your rights as a citizen to elect representatives who understand and are willing to make the necessary changes to keep our water and environment safe.

What if instead the glass was really half empty, and contained a vacuum and water?

Check out xkcd’s What If series to find amusing and informative answers to those slightly ridiculous questions that you’re too embarrassed to ask others!

We seem to be really close to finding some sort of life on these large moons. Strengthening this possibility is recent evidence that Saturn’s moon Titan “squishes” due to Saturn’s gravitational pull. Hard material like rock wouldn’t have as much of a squish (reported to be about 10m), and the denseness of water would put it under the relatively light ethane and methane lakes on the surface.

NASA finds hidden ocean on Saturn’s moon Titan

Using incredibly precise measurements from NASA’s Cassini spacecraft, researchers have concluded that Saturn’s biggest moon is likely hiding a global, sub-surface water ocean, 100 km beneath its surface.

Cassini has flown by Titan more than 80 times since entering Saturn’s orbit in 2004, and its observations have confirmed that, as moons go, Titan is a weird one. It’s bigger than the planet Mercury. It’s the only moon with a real atmosphere (an atmosphere denser than Earth’s, in fact). It experiences Earthlike weather, such as rain and snow. It’s home to familiar geological features like valleys, plains and deserts — and it’s the only known object besides Earth with standing bodies of liquid.

The researchers’ findings are published in the latest issue of Science

Ahh, soothing fluid dynamics.

Slow-mo fluid dynamics is a beautiful science!
