Aysha does, actually more than six hours, says UNICEF:
How Long Does It Take to Get Water? For Aysha, Eight Hours a Day
Worldwide, women and girls spend an estimated 200 million hours — every day — collecting water. It’s a colossal waste of their valuable time.
Thirteen-year-old Aysha, in Afar, Ethiopia, must trudge eight hours, round trip, to ...
By most standards, the answer is no.
A navy, strictly defined, is an armed force for prosecuting warfare on bodies of water. The Walt Disney Company has no known ships that would meet this definition. For the sake of discussion, of course, we'll take navy as a jocular synonym for fleet, giving them a foot in the door.
A second consideration is that a navy ...
As published in "Do Fish Fall from the Sky?" Science vol. 109 page 402,
On October 23, 1947, biologist Alexander Dimitrivitch Bajkov, PhD was eating breakfast with his wife at a restaurant in Marksville, Louisiana when the waitress told them that fish were falling from the sky.

Politifact gave this old story about the Nazis and fluoride a "Pants On Fire" rating:
"Truth about fluoride doesn't include Nazi myth"
...We tracked down roots of these claims on the Web, reached out to Holocaust historians, contacted well-known critics of water fluoridation, and read book excerpts and magazine articles and news stories. And we can tell ...
As a scuba diver I can assure you it's possible. One thing you need to do to get your licence is to breathe from a stream of bubbles from a free-flowing (faulty) regulator. That kind of fault causes the air to flow freely from the air tank, generating a major stream of bubbles. By placing your mouth over that stream you can breathe from it. Even though we ...
No, you do not drink water before you feel thirsty.

Bottom line: drinking ahead of thirst
General public—Drinking ahead of thirst may worsen performance in endurance exercise and carries a rare but serious risk of hyponatraemia. The body’s internal mechanism for staying hydrated is ...
Words are just that – words. They have no power whatsoever and the laws of physics do not distinguish between "good" words and "bad" words.
You speak English, which happens to be one of many thousands of languages that have developed over the centuries. There is no general rule that allows you to categorise "good" words and "bad" words. In some languages ...
I'm going to assume a quarter pound (113 g) burger with no cheese or other added feature. This being the case the bread can be neglected as the water-cost of beef is going to dominate. I'm also assuming that the unit of volume being used is the American gallon and not the imperial gallon.
The answer is definitely going to depend upon how you raise the ...
Not an authoritative source , just a blogger, but a decent attempt to explain some of the cali water issues that's reasonably well sourced itself.
California receives a total of 80 million acre-feet [99 km³] of water per year. Of those, 23 million [28 km³] are stuck in wild rivers (the hydrological phenomenon, not the theme park). These aren’t dammed and ...
As for claim, that "98% of Europe banned water fluoridation". Without going much into detail:
population of European Union is 503 million;
according to claim's source, following EU countries have at least one active fluoridation program:
UK (62mln, 11% using fluoridated water)
Spain (47mln, 11% using fluoridated water)
Poland (39mln, 1% using fluoridated ...
This incident did happen.
The Kenyan newspaper The People has an article on the incident here.
The website for the Zheng-Kai marathon also confirms most of the story. The results of the 2010 race show that Jacquline Nyetipei finished 2nd. The time for the split shows the first 5 women together. This suggests that she did indeed have a good chance of ...
I am addressing the cited claim (not the different form stated at the top of the question)
Do not mix raw and boiled water! Grandma was right. Just why mixing of boiled and raw water leads to a rapid emptying of the bowel, the science cannot explain yet. But the fact is obvious.
The World Health Organisation (WHO) recommend that water be raised to a ...
Yes, it is to a large extent.
This paper by Lian et al. explores the formation of volatile chlorinated compounds that are formed from reactions with organic nitrogen compounds, such as urea, amino acids, uric acid and creatinine.
The authors exposed both dilute solutions of uric acid and bodily fluid analogs (mixtures of compounds intended to mimic the ...
Can you extract over 500 gallons of water from the air a day for a few cents per bottle?
Well, first, the "500 gallons" part is an irrelevant distraction. If there's a machine that can extract 1 gallon a day, then 500 of them would be able to extract 500. What about the "few cents" part? That falls into the "technically true" category. However, there are a ...
The nature of the device
First of all a clarification.
Their product, a jug which causes a vortex:
is not a jug alone and the jug doesn't cause a vortex. This a magnetic stirrer. These devices are on sale now, arguably in less attractive form factor for house hold appliances (aesthetics feelings may vary):
These products do create a vortex. But ...
To answer your question, "Is there a place in the world where two oceans meet and they don't mix?" No, the water mixes it just isn't instantaneous. Saline, temperature differences, and pollutants can cause them to appear as if they don't mix for a period of time, especially if there aren't strong currents.
According to Ken Bruland, a professor of ocean ...
Yes, what you see is real. However, as @Oddthinking points out, this happens because of the sync between the frequency of the camera and the frequency of the sound wave. If you make this experiment at your home without a camera that is shooting at the same frames per second (fps) rate as the frequency of the sound wave you'll not see the same effect with ...
According to Wikipedia:
Cholera is an infection of the small intestine caused by the bacterium Vibrio cholerae.
Thus, if a watermelon or any water contains that bacterium, you will get cholera from consuming it. The combination does not matter. If you consume things that don't contain this bacterium, you will not get cholera, no matter which things or in ...
"To me this seems complete nonsense."
As it does to anyone that looks any further than the company's own advertising.

The two key points are that the patent has nothing to do with whether the device actually does anything ...
Water is cheap. In the UK 1 cubic meter of water (1000 litres) costs around £1.45. So even if you could save 20,000 litres of water by peeing in the shower that would only be £29, which at current exchange rates is about $50.
According to this report "fluoridation schemes operate in five countries in Europe -- in the UK, The Irish republic, Spain, Poland ans Serbia", for a total coverage of about 13,677,000 people (even in those countries only some parts are covered). Excluding Serbia and Poland that would be 13.397,000. According to Google Western Europe has a population of ...
Chlorine does evaporate, so if exposed to air (e.g. in a bucket) in warm water (especially under UV light or sunlight) it will probably mostly dissipate overnight.
Both fluoride and chloramine will not similarly dissipate, if you want them removed you need to filter them out (e.g. with activated carbon) or distill the water.
Can You Remove Fluoride ...

Speaking about Germany, the health regulations for tap water are somewhat tighter than for bottled water - specifically, they cover more contaminants. But of course both are intended to be perfectly safe to consume.

The claim that plastic shade balls used in the LA reservoir leach chemicals into drinking water can be denied based on the following points.
The shade balls are coated in carbon black, a food-safe pigment with an albedo near zero. Any sunlight that is absorbed by the ball is not reflected or refracted since its basically dark. Dark colors absorb light and ...
