Why is it easier to tear wet paper than dry paper?

Nice question.Paper consists of a network of cellulose fibers.

The fibers adhere to one another partly due to hydrogen bonds. Adding water to the paper allows some of the interfiber bonds to be replaced with bonds to water molecules instead, so some of the interfiber bonds are broken up. Thus the material tears more easily when thoroughly wet than when dry.
