I don’t remember all of the details, but I thought it was essentially the water’s surface tension that foots the energy bill when climbing a paper towel or a capillary in a tree.

The surface of fluids like water are unhappy. Molecules on the surface would much rather be deep in the fluid because on the surface they have “dangling” Van der Waals & polar bonds to one side. You can calculate the potential energy of the surface due to all of those dangling weak bonds, & that’s the energy that is used to climb a capillary (the energy isn’t free).

I could be misremembering though, I admit. School was many years ago…

Nice clothes. She likes Free People, Anthropology, & Sundance. I try to choose a dress or jacket or something I think she might like (always get a gift receipt though!)

Small things. Sounds. The temperature of the air. The fact that my side isn’t hurting right now. The kids costumes who were just trick or treating at my house.

I’d rather teenagers be trick or treating than doing other stuff. If they come to my house they’ll get candy for sure.
