And for this here, there's some very, very new research coming out. The older research, it ties in with the newer research, has some commonality to it. But the new research is showing that it's not from the friction and pressure. And this is written up in physical review letters. And friction and pressure produce a thin layer of water. And that still holds, but for a different reason. Computer models are now indicating that molecules can have what's referred to as molecular dipoles. And molecular dipoles, that's... Molecules can have both a positive and negative charge regions on them. So the overall polarity points in one direction. However, with this new research, what they've found here now is that water went free. Molecules, they form into a crystal lattice structure. So when you step on ice, the orientation of the dipole in the shoe or skate, and those in the ice, changes. So they become disordered. So the force between the skate and the ice produces a disordered state where the liquid forms. So it's not necessarily from the pressure itself. It's that the pressure is producing these... The dipoles are going to a disordered state. The charges get all disordered. And the lattice work breaks down a bit and produces ice. So much the same with what you're saying, Scott, but just a little bit different than what I know.
