Transcript: Dr. Gerald Pollack on The Fourth Phase of Water at TEDxGuelphU

Also the phases of water. Now we’ve all learned that there’s a solid phase, a liquid phase and a vapor phase. However, a hundred years ago, there was some idea that there might be a fourth phase, somewhere in between a solid and a liquid. Sir William Hardy, a famous physical chemist, a hundred years ago exactly, professed that there was actually a fourth phase of water, and this water was kind of more ordered than other kinds of water, and in fact had a gel-like consistency.

So, the question arose to us — you know, all of this was forgotten, because people began, as methods improved, to begin to study molecules instead of ensembles of molecules, and people forgot about the collectivity of water molecules and began looking, the same as in biology, began looking at individual molecules and lost sight of the collection. So, we thought we’re going to look at this because we had some idea that it’s possible that this missing link, this fourth phase, might actually be the missing link so that we can understand the phenomena regarding water that we don’t understand.

So, we started by looking somewhere between a solid and a liquid. And the first experiments that we did get us going. We took a gel, that’s the solid, and we put it next to water. And we added some particles to the water because we had the sense that particles would show us something. And sure enough you can see what happened is that the particles began moving away from the interface between the gel and the water, and they just kept moving and moving and moving. And they wound up stopping at a distance that’s roughly the size of one of your hairs. Now, that may seem small, but by molecular dimensions that’s practically infinite. It’s a huge dimension.

So, we began studying the properties of this zone, and we called it, for obvious reasons, the exclusion zone, because practically everything you put there would get excluded, would get expelled from the zone as it builds up, or instead of exclusion zone, EZ for short. And so we found that the kinds of materials that would create or nucleate this kind of zone, not just gels, but we found that practically every water-loving, or so-called hydrophilic surface could do exactly that, creating the EZ water. And as the EZ water builds, it would expel all the solutes or particles, whatever into the bulk water.
