It is evident that an acquaintance with natural laws means no less than an acquaintance with the mind of God therein expressed.
James Joule, propounder of the first law of thermodynamics (on the conservation of energy). He also made important contributions to the kinetic theory of gases. The unit of heat known as the “Joule” is named after him. Joule was a devout Christian.

Did you know you can create a cloud at ground level? It's not smoke or artificial fog; it's a cloud made of water vapor. The Cloud Bottle lets you pressurize a small amount of air and water, raising the temperature. When you release the top, due to rapid decompression, a small cloud is formed inside the bottle. A Liquid Crystal thermometer strip measures the temperature as you go. It's a tiny piece of hand-held science that's sure to amaze and astound.
This will be a simple short post, mainly talking about why domestic ice cubes are cloudy :)
Ice, as you should know, are frozen water aka water in solid form.
And ice cubes, is simply ice shaped in cubes DUH.
If you've ever wondered why the ice cubes you froze in the fridge is always cloudy and never clear...
This is because just like how there's dust everywhere in the air, noticeably under sunlight, there's sediments and particles, dissolved air and minerals in water. Because of spaces in water molecules, tiny stuff like a bunch of air molecules slips in between water molecules easily...
And when water freezes up, it freezes from top to bottom. This causes the particles, air and other molecules to be trapped in the (about-to-be) ice. Once it freezes up as ice, it is no longer a liquid remember? It's in a solid state.
This means that the dissolved (molecules that got mixed inside water) particles and air must appear because in a solid state, the ice only vibrates closely. Hence, the air molecules are forced out of the tightly-packed ice particles, creating the cloudy look.
If you are now wondering why it's not a clear look with bubbles in it, this is because the dissolved gases are very small and they don't have the time or will to merge together to form even a tiny bubble in the ice :]

The same way water evaporates from the open surface, water freezes from the open surface too! It's not necessary from the top. oops.
As water becomes ice, the particles move slower and slower until they form a pattern and vibrate in their position. While gas particles also slow down, they don't stick to each other as they are free.
The more surface area of an ice cube, the more heat it can absorb! Think how you can use that to your advantage ;) (The faster it melts too~)
Something for making it through this waterfall of information…
Clear Ice Cubes!
Because those cloudiness are the result of mostly air particles trapped, one way is to boil the water once or even twice! before freezing it.
Do take note. Putting hot water into your fridge may spoil it!
Another "water" you can use is pure/purified/distilled water.
