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 ...
The linked site mentions that this has been validated by the USPTO. Not true. John Ellis has a few patents on distillers that do not mention hydrogen bonds (from USPTO patent search site with search string IN/"Ellis, Jr; John C"

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 ...
There is a lot to unpack from that site; the majority of it seems to have little basis in reality. The short answer is that you cannot permanently change the hydrogen bond angle (104.5°) in water.
EDIT: Free H+ binds to water molecules to form H30+ hyrdonium ions which do have a bond angle of 113°, these are small in number even in very strong acids and ...
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 ...
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 ...
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 ...
"To me this seems complete nonsense."
As it does to anyone that looks any further than the company's own advertising.
McGill University's Office for Science and Society ("Separating Sense from Nonsense") has a report on the magnetic laundry device.
The two key points are that the patent has nothing to do with whether the device actually does anything ...
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 ...
Question: Can anything be more hydrating than plain water?
Yes, fluids that contain certain amount of sugars and sodium can be more hydrating than plain water, which can be beneficial in prevention or treatment of dehydration during prolonged endurance exercise (Nutrition & Metabolism, 2009).
In everyday life, when you are not dehydrated ...
Since the question refers to a college campus in the USA, I will quote information from UC Berkley.
DO NOT GENERALIZE TO OUTSIDE THE USA.

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 ...
A new paper on this phenomenon has been published recently. It offers yet another explanation and has even caught the attention of popular media.

Summary: No, it seems vegetable washes (a.k.a. produce washes) generally don't really help remove pesticides... but that isn't the point of them... but even at their main task of removing microbes, they may or may not be effective.
Are Pesticides the Real Problem?
We wash produce to remove a number of contaminants:
Microbes including ...
When chipped: definitely
The key to answering the question is here:
Mr Carter also warned motorists of the danger of existing chips in the windscreen.
"A seemingly insignificant chip in the glass can cause significant damage if hot or boiling water is poured onto the windscreen when it is covered in a layer of ice.
"In very cold weather, putting ...
Snopes rates this claim as false.
"Did the man claim to be swallowed by a whale?" No.
The article features the image of shirtless man that is claimed to be the fisherman, Luigi Marquez — but it isn’t. The man pictured is actually named “Mike” and the picture was taken from a 2015 YouTube video in which Mike demonstrates turning his swim trunks into a ...
First of all, Google can find quite a lot of background on the dispute between Steve Lipsky and Range Resources Corp. This article is a summary of the situation, where Range Resources Corp. has been drilling for gas close to Lipsky's estate, after which Lipsky is blaming the company for ruining a well, from which he used to get his fresh water supply. It is ...
There's some evidence that drinking a large amount before eating a meal will help because it makes you feel more full, thus leading to eating less food, but sipping it during your meal doesn't help much because the water is absorbed much faster than the food.
People sometimes drink water with meals to promote a feeling of
fullness, in hopes of helping ...
There is no convincing evidence that consumption of caffeine or tea leads to dehydration (fluid loss) based on available research. Studies cited below indicate (a) that caffeine is a not a very efficient diuretic, (b) that coffee/tea's diuretic effects are similar to that of water and (c) that moderate caffeine consumption does not lead to dehydration.
No, the claim is faulty on both parts
Using the US Geological Survey report on Estimated use of water in the United States in 2015, we quickly see that the original claim that thermoelectrical power-plants consume the most water is not correct.
Table 2A shows that thermoelectrical power plants do withdraw 133,000 Mgal per day, and that is on par with ...
I can't give a complete answer.That would require original research and/or actually testing a unit for an extended period of time.
But some of the statements on that page aren't correct and weaken their claims. I'm going to focus on a single one.
That link includes this picture.

No, not in the sense that you mean. It isn't only Mythbusters that have debunked this one. Even if your feet only make contact for a brief moment, the weight of a human, plus the weight distribution of a person makes balancing on a dynamic very difficult.

Walking on water is a popular magic trick, but it's ...
I get about:
coffee: 80 liters per cup
cotton: 10000 liters per kg
The differences could be due to the original calculation including run off pollutants. But the numbers are actually pretty close for a back of the envelope calculation. There are some details about this in the cotton water footprint report below.
The available evidence suggests:
Drinking distilled water in usual amounts in everyday life, which includes regular meals, does not likely remove needed minerals from the human body in significant (harmful) amounts.
Drinking large amounts of distilled water in a short time can result in water intoxication, but the danger is about the same as ...
There was a joint Hungarian-German study on the subject led by Dr. Gábor Horváth at Eötvös University in Budapest, Hungary.
A team of physicists, troubled by the lack of scientific evidence for the phenomenon, set out to test the theory that water droplets on leaves can act like mini magnifying lenses, focusing the sun's rays and leaving a leaf's surface ...
Yes, atmospheric water does contain small amounts of elements and minerals, and the types and amounts of minerals vary based on location. Unfortunately, since Scalene Aquaria's claim doesn't seem to address which minerals it is balancing or what 'balanced amounts' of those minerals are, so we can't be sure one way or the other whether their claim of '...
