I heard another claim about smaller water molecules . They are supposedly absorbed by the body more easily. I don't remember the brand but I saw it on E! Television so it was popular with the Hollywood set.

You are talking about the normal boiling point; the temperature at which the vapour pressure of the water reaches 1 atmosphere. As I explained before at temperatures (much) lower than 100 C, water has a significant vapour pressure, the which is responsible for evaporation. Change the ambient pressure (up or down) as you say and you will change the temperature of the boiling point.

For further proof, pour a few drops of water on the counter top in a 65 degree (F) room and give it an hour or two.
That was an assumption on my part - the real point though was whatever the evap temp they were talking about was, the difference between the evap times of the possible forms of water due to the isotopes of Hydrogen will be too small to matter as they suggested it would. Just as a side, crushing/distilling fruit material to get water sounds awfully expensive compared to opening a tap or buying a lake house in the Outback.

Of course the ultimate in no-taste water is to just distill your own.

I do!

Distiller cost like 99 dollars. Price per gallon is much cheaper than any water you can buy.

Oh, nuts - worried about some evil minerals plating out on your gizzard, I suppose. Tell you what - distill all the water out of a pot full of wholesome oatmeal. What does that tell you about what isn't actually water there?

Can you be more specific? Goo can mean so many things. Are you saying you got organic chemicals, solvents, sludge form your tap water? Your tank was clean, you house piping undamaged when you started? Have you sued your water district lately?

Our tap or well water in Colorado often contains dissolved salts, but never organics or goo in more than trace amounts. I kind of suspect hyperbole, but maybe not.

Well, our well water when I was growing up had lots of sulfur in it, and I know of people who have petroleum in theirs (only traces) so I can imagine some pretty nasty boiler scale in a distiller.

BTW, boiler scale is one of the ENEMIES when you run steam engines; un-dealt-with it can destroy the ability of the boiler to transmit heat from the firebox to the water and cause a boiler explosion. In practice one "blows down" the boiler through valves in the mud ring and also the water is treated to prevent scale from forming a solid mass using a variety of different formulations.

I've heard that drinking distilled water is harmfull, eventually.
Might need to mix some minerals back in.

btw,
Years ago I read that very pure water has a lower freezing temp than more normal water.
The ice crystals initially form around a speck of adulterant; when there aren't any, it takes more energy to begin the crystalization.

Is this wrong?
(I defer to smart people)

No, the amount of minerals in water is SO miniscule that it maybe accounts for 1-2% of your daily intake. No need to replace any minerals if you drink distilled water.

Yes, this is mostly wrong.

Ultrapure water will tend to supercool, i.e., it can be cooled to lower than its freezing point without freezing, until either a speck of something solid is introduced as a crystallization site, or the sample is given a shake. Then it will immediately start freezing and it will heat up to zero degrees Celcius. But it still has the same freezing temperature, and it has more to do with kinetics than energy.

It's tough to do this with water, but there's a number of organic compounds which make easy demonstrations of supercooling (I seem to remember thymol is a favourite).

Those standards vary though - and some results depend on the condition of the delivery system (pipes/pipe condition, your pipes, pumping stations and their maintainance). Just today, discovered that you can now be tracked for a reasonable time back as to where you have been and about how long in each place because the water in every place has different concentrations of H and O isotopes and these somehow attach to your hair as it grows. They are now collecting data of that for "research". I'll go see if I can find this again (to verify - it's either under neutron or electron research). Back shortly!!

Here it is :http://pubs.acs.org/cen/news/86/i09/8609news6.html

You might also want to (same source, different article) look at the totally unrelated but neat way they measure the friction of a single atom being moved over a surface. Ain't real science grand!!!!!

I live in Colorado, have been to "Red Rocks" (in Morrison) and I like to drink Coors after work, a lot. My tap water is from Pikes Peak, melted snow that flows into the Gillette Flats, if I could bottle and sell it, I wouldn't have to go to work next Monday!

Does this post have anything to do with the OP? not really, but I did ride my bike through Sydney in '96 and the water sucked there! (Not s bad as the Bore water in NZ though)

Water is "Water", IMHO as long as it tastes like "Nothing"!

I like Coors!

I went to this business woman thingy. There was this one lady with skin care products... with fruit listed as ingredients among other things, like grapefruit and water chestnuts.
She went on and on about how her products have no chemicals in them, no toxins, etc. All natural.

Um. heh heh. No chemicals? So, I told her that water was a chemical...

Oh, she assured me that there was no water in her products... no problemo.

You mean the way the bottle water from Pepsi and Coke are really the water they had anyways, in the bottles they had anyways, without any of the ingredients, and for the same price?

I agree that this was a great idea for the seller. After concentrating fruit juice, selling the water under any pretext makes more money than pouring it down the drain. As for the taste and "solids" content, I am told that distilled water is quite bland. I do know that some bottlers of purified water add a trace of calcium chloride to enhance the flavor. I assume they also aerate it to get a little carbon dioxide for flavor, as well.

Concerning the Formula Weight (FW) of the water (18 vs. 20), if I recall the OP, the water is evaporated at low temps, which slightly favors evaporation of FW=18. So, technically they may be correct. However, although sensitive instruments can measure the ratio of FW18/FW20, it is insignificant in terms of the biological properties. Scientists studying climate change as seen in glacial ice cores use the FW ratio in the ice to determine ocean surface temps through history.

cool.

allow me to add another bit of linkless drivel:

Perhaps 10 years ago, I read an article in a science mag. Possibly a good one.

There was an experiment to squash water beyond what has ever been done on earth.
A press was constructed that held a sub-drop sized quantity of water.
(Oddly enough, the crushing force was applied manually, thru gears)

The resulting pressure was described in "oceans", which, if memory serves, is the pressure at the deepest spot in the ocean.
Apologies for not recalling the number of 'oceans' applied, but it was a crap-load.

As i also recall, a new crystal formation was acheived.
(any one that knows of this and can provide a link is my hero)

It wasn't ice-9, evidently.
