The thing that causes any slick feeling is a lack of resistance or friction when rubbing your fingers together-If bases actually caused decreased viscosity, and decreased the frictional aspects of a surface, then bases solution on other surfaces would cause them to be slick as well-if it were just disintigration of skin, then this reduced viscosity would only work with skin. IN truth, bases *do* decrease frictional aspects (one of the reasons soapy solutions work as lubricants)- because bases are negatively charges, and most surfaces, including skin, arenegatively charged, this tends to decrease the interaction of the fluid with the surface. Even if the surface is positively charged, very quickly these are reacted with OH- ions in the base, and again, the solution makes the surface *slick* from decreased electrical interaction, in much the same way oils are slick-they have no charge at all, and thus do not interact electrically with charged surfaces.

Simply:
Like charges repel each other. Bases produce neg-neg. Kinda like two like poles of a magnet brought together.
Note: The stronger bases do destroy skin. Weaker bases clean (soaps) because they dissolve oils.
Get an "A".

I don't know for sure, but I always thought it's because your skin "melts" when it comes in contact with a base, and that's why it feels that way.
