Vaping water?

I don't think vaping water would be safe, it's one thing to sit in a sauna and relax a totally different thing to try to vape it, plus it'll prolly taste like crap 
You could vape water if you got the coil hot enough. However, the restrictions would be a pain in the ..... You would get very limited vapor, and you would need incredible wicking cause the water is not as dense, so it will "steam" much faster. It would turn into one big waste of time.
Vaporizing is a different phenomenon than boiling. Water will boil, which generates hot steam.
PG and VG act differently than water. When heated, a tiny bit does "boil off" (that's not absolutely correct, but the closest I can come to a description). However, it pulls a small blob of liquid along with it. The vapor is actually tiny drops of liquid, not re-condensed steam, and the vapor is MUCH cooler than what you would get by actually boiling PG or VG.
Water doesn't do that, it's not viscous enough. It just sits there until it boils.

And, as the latent heat for water is one of the biggest known for any liquid, and that heat is freed when water thickens, you will probably be chapped by that heat. It is also the main reason not to reduce mixtures viscosity (high VG grades) with too much deionized water ....
2257 J/g, or 970 BTU/lb..... way to much for our lips and tongue. PG/VG mixtures are not so warm when thicken, or do not require so much heat to get vaporized...

Water would most likely drain out past the coil and on through the bottom air holes in most tanks. Flooding would occur immediately. You could try it in a carto where there's more filler to hold it in suspension, but expect a hot steam that burns your lips. It won't be fun or tasty and the vapor will condense in your mouth. There will be little or no exhale. Vaping hardware is designed for juices with some viscosity.
if your vaping e-juice,you are vaping water.
PG and VG are hygroscopic. they attract water
in proportion to the relative humidity in the air
and what they are mixed in.
the purity of PG and VG determines the grade.
any impurities left are 99.9% water.
some juice makers add distilled water from 3 to 15 or 20 % water.
most cigalikes have water added to preserve shelf life and enhance
vapor production.
the first modern day e-cigarette used a sonic vibrator to atomize
the PG mix into a mist for inhalation.
somewhere along the line it was discovered that by adding a
little water you could use a simple less expensive heating coil
that would vaporize the water that would atomize the PG and
also give it a more smoke like appearance.
e-juice will naturally have 1.5 to 3 % water by volume and
with the more powerful advance devises that is all that is
needed to start the process.

"Cigarettes are like squirrels. Perfectly harmless until you put one in your mouth and light it on fire" love that!!!!! Almost fell out of my chair I laughed so hard. Funny!!

MarsRising, thank you for posting this question!
I'd wondered the same thing when I started vaping, "PG, VG? Wait, why don't we just use water?" But I didn't easily find the answer when Googling. Then I got distracted by all sorts of other vaping-related questions and forgot about this one until I saw your thread here.
Thanks to everyone for posting plausible, scientific-sounding explanations and histories, too!

PG and VG inherently contain about 10% +/- water. Another 10% or more is sometimes added to some juices if thinning is needed.
There's water vapor in the vapor from our ecigs, but it's a byproduct of heating glycerine type products. You can dry burn a used RBA coil (wick removed) and get vapor. Wet the same coil after the first dry burn and then dry burn again and you get hissing and sizzling, but very little water vapor once the PG and VG is burned off. The little bit you get from plain old water wouldn't be worth vaping.
