Dolphins are widely considered as one of the smartest animals on this planet, and often leave lasting impressions on people with the clever tricks they perform in zoos or dolphinarium. They are friendly and social animals that have rescued humans from shark attacks and drowning. Like how dogs are “man’s best friend”, dolphins are our best friends from the sea.

7 Amazing Facts about Dolphins
Telling Children about Water: Experiments for Little Ones
What do you think, is it possible to get a rainbow at home? Is it possible to grow real crystals in a regular glass? Can you build the desalination plant from scrap materials? The answer is yes, and it’s not alchemy and not magic. You can do all this and much more at home with the children. Plain water and a set of elementary gadgets will help us.
Experiments with pure water
Even the most ordinary water flowing from the tap, is not as simple as it seems. Its physical properties are full of many mysteries and secrets. Let’s try to unravel some of them. Read more
Boiling water makes for cooler electronics
Boiling water seems a straightforward enough exercise, you flick on the gas and wait for the bubbles to start popping. But by manipulating how many of those bubbles appear as the temperature rises, scientists have discovered a new way to finely control how much heat and steam is released in the process, a technique they say could lead to advanced cooling systems for more efficient electronic devices.
By altering this hydrophobic-hydrophilic balance of the material, the scientists can precisely control where and when the bubbles form. This in turn allows them to regulate the boiling and condensation processes and how much heat is transferred along the way. Read more
This self-filling water bottle is the ultimate in vaporware
Austrian startup Fontus is developing a novel water bottle that is vaporware in just about every sense of the phrase. Not only does it not yet exist in the marketplace, but it is claimed to literally pull water vapor out of the air to fill itself.
Cool Runnings: Lockheed using microscopic drops of water to chill chips from the inside
Every year, electronic components shrink a bit more, allowing engineers to create more powerful and sophisticated chips. Unfortunately, these chips also generate a lot of heat, so novel cooling systems are needed to keep them running. As part of DARPA’s ICECool-Applications research program, Lockheed Martin is developing a way of cooling high-powered microchips from the inside using microscopic drops of water.
