Ive read that distilled water helps with the flavor not sticking, so a lot of people use a small percentage of it.
Any ideas on what a 50/ 50 blend with VG and distilled water would work?
I think you would burn through flavors pretty quick, but not sure
A 50/50 mix would not, IMHO vape at all.
Vaporization is very different than boiling. PG and VG will both vaporize because of their chemical makeup. Vaporizing is not turning the liquid into a gas, it is turning the liquid into very small droplets of liquid. Water will vaporize in a spray (i.e. mechanically) but it won't vaporize by heating it with a coil; it will just boil.
When PG/VG vaporizes, I do believe that a tiny bit of it actually does boil. However it has such a strong attraction to itself that a tiny puff of gas pulls a much larger blob of liquid with it. This is why it doesn't totally take the skin off your lungs; the droplets get shot off at a temperature much lower than the boiling point of the liquid. Water, despite being a polar molecule (with some surface tension and viscosity) just doesn't do this. Water, Saline, and alcohol can be added in small amounts to affect the viscosity, throat hit, and flavor. But they can't be major components, or the liquid will be unvapeable.
