What? Of course distilled water boils. Every liquid boils. It may not boil in the microwave, but it boils.

Boiling water depletes it of oxygen, allowing it to freeze faster than an equal colder water sample. Ordinary hot water doesn't freeze faster than ordinary cold water, unless it's been boiled. At least, that's what I've read.

Distill your own water, and make sure the container your using is clean(dish washers tend to leave trace mineral deposits, and the no spot rinse chemical leaves a film) and free of any minerals or other foreign cleaners. Then try again, it won't boil.

I did...They are both frozen. Wonder which one will thaw first?

Don't have to google my answers.

But I had seen that episode from Mythbusters along time ago.

Also discovered that some of the distilled water you buy from a store, isn't as pure as it should be.

Where I work we have a deionized water system that removes all the chemicals and sediment from the incoming water. Additionally, the water is added to a vessel through a 0.2 micron filter. The vessel has been cleaned and tested to a residue of 0.14 au through a UV spectrometer and a high pressure liquid chromatography unit. I can assure you that the water boils and at 100C.

Now distill it. And see what happens.

I can make water boil at 32 deg f.

Just so everyone understands, when water boils, those bubbles you see are the result of steam....in other words, the vapor phase of water has been reached.

That temperature for distilled water is 211.997 deg F (distilled water boils).....adding salt to the water or glycol will raise that temperature point just slightly...but the water will boil.

Regarding the OP's original post. I did some searching on the topic.....it's pretty obvious that this is one of those things that can only happen under very specific conditions. Given the fact that no one has posted the steps to allow someone to duplicate the experiment....I'm not going to hold my breath on it being valid......somehow, memories of cold fusion come to mind....

The distillate has been reloaded many times without being exposed to an oxygen atmosphere and reboiled.

Not trying to argue but I deal with this on a regular basis, in the plant area and in a lab. I can't say for sure how little impurity is required and there may be some still present, outside of the most expensive distillation and filtration systems, but I would think our systems can get it low enough to meet the requirement for the water to not boil.
(It doesn't appear to boil, if that's what you're talking about. But it is boiling, as evidenced by the distillate that condenses on the cooling coils)

The old distilled water does not boil trick. The small bit of fact in this legend is that water, like all liquids, requires nucleation to freeze and boil efficiently. In most samples of water, there is plenty of contamination, including dissolved minerals, to provide ample nucleation sites for boiling or freezing. Even the sides of the container typically provide nucleation sites, you can see this if you boil water in a glass beaker, there will be spots on the sides and the bottom where boiling is concentrated. In our old chemistry lab, we used boiling chips (magnesium carbonate as I recall) to provide nucleation sites to make the boiling even.

When boiling very pure water, there may be very few nucleation sites, which can create erratic boiling or even conditions where the water gets hotter than 100 degrees C before it boils (this is called superheating). This can be dangerous, as the water can boil violently when it undergoes rapid phase change once it starts to boil, which generally occurs a few degrees above normal boiling temperature. A similar phenomena happens when freezing, if there are no nucleation sites water can be cooled well below normal freezing temperature (supercooled water) without phase change to ice. When the water finally freezes, which can be set off by a slight shake or similar event, it will freeze remarkably quickly. There is a nice video of this effect, see http://www.youtube.com/watch?v=DpiUZI_3o8s.

There is a good discussion of superheating on Wikipedia, see http://en.wikipedia.org/wiki/Superheating
