A few years ago, I wrote a post on Neatorama that became one of my favorites: 5 Really Weird Things About Water.
Actually, there are a lot more than 5 weird things about good ol' H2O. Like this newly discovered quantum properties of water in carbon nanotubes, for instance:
It turns out that the protons in this nano-confined water at room temperature behave in an entirely different way to those in bulk water. Protons are known to be sensitive to the electronic fields around them. So when these fields form into unusual electronic networks, it's no surprise the protons behave differently.
"The departures of the momentum distribution of the protons from that of bulk water are so large, that we believe that the nano-confifined water can be properly described as being in a qualitatively different quantum ground state from that of bulk water," they say.
They even suggest that there could be some kind of quantum coherence that spreads out through the electronic network.
