Why are your fingers wrinkly when wet?

Why?

[EveronVetsAgainstTheWar 1]

The tips of fingers and toes are covered in a tough, thick layer of skin which, when soaked for a long time, absorbs water and expands. However, because there is no room for this expansion the skin buckles, hence the wrinkles.

Im impressed, a spam thread (or nearly so) that hasn't been locked yet.

I don't see this thread as spam. He wanted to ask a question, and he asked it.

If it were to be closed, it would be because the question is answered. Not because the thread is spam.

Yeah, he could have asked within an existing thread, but that would definitly be spam.

well I guess, but threads get closed for less that this don't they?

Only since Denoir.

If Denoir can do it, so can we!

Your skin cells absorb so much water they expand. Thus, they collapse over eachother because of their increased weight. Causing Wrinkes until somposis drains toe water out of the cells in which returning them to their normal state.

Answer: Osmosis

Osmosis, in botany and chemistry, the flow of one constituent of a solution through a membrane while the other constituents are blocked and unable to pass through the membrane. Experimentation is necessary to determine which membranes permit selective flow, or osmosis, because not all membranes act in this way. Many membranes allow all or none of the constituents of a solution to pass through; only a few allow a selective flow. In classic demonstration of osmosis, a vertical tube containing a solution of sugar, with its lower end closed off by a semipermeable membrane, is placed in a container of water. As the water passes through the membrane into the tube, the level of sugar solution in the tube rises visibly. A semipermeable membrane that may be used for such a demonstration is the membrane found just inside the shell of an egg, that is, the film that keeps the white of the egg from direct contact with the shell. In this demonstration, the water moves in both directions through the membrane; the flow is greater from the vessel of pure water, however, because the concentration of water is greater there, that is, fewer dissolved substances exist in this solution than in the sugar solution. The level of liquid in the tube of sugar solution will eventually rise until the flow of water from the tube of sugar solution, under the influence of hydrostatic pressure, just equals the flow of water into the tube. Thereafter, no further rise in level will occur. The hydrostatic pressure establishing this equality of flow is called osmotic pressure. A variety of physical and chemical principles is involved in the phenomenon of osmosis in animals and plants.

As stated by someone earlier the cells take on excess amounts of water, but this explains why.

Valid and interesting question, not spam IMO and I learned something I never knew

Not only would it be spam but confusing.
