|Subject: ||Physics question: why does water (a lubricant) cause blisters?|
Why is it that when your socks get wet, e.g. running in the rain, you tend to get blisters, which are caused by increased friction, right?
More generally why is water in some cases act as a lubricant (e.g. trying to stop your car on a wet road) and in other case an anti-lube (e.g. wetting your thumb in order to better thumb thru some papers (or some money).
