Dry fingers sometimes cannot separate sheets of paper because they just slide on the top sheet. Damp fingers create friction and adherence to the top sheet enabling you to separate it from the next one down.
Because the fibers that make up the paper are wet and slide apart easier
It has to do with friction. The smooth paper allows the pen or pencil to slide while rougher paper doesn't.
sand paper increases friction, that is to say that it is harder to slide something on sand paper than it is on a smooth surface.

Yes, because they work by shedding rubber to discard the removed graphite. That shedding requires a mechanical rubbing action, and that will inevitably force some graphite deeper into the paper. ... Rolling, or dabbing, is the preferred way to use kneadable erasers, because they absorb graphite.

You slide the small plastic hatch off the right side of the eraser (opposite side to eraser), not the one on the bottom. You can use two AAA batteries.

A Slip N Slide is an outdoor water toy for children. It is a long sheet of plastic that becomes slippery when wet. After wetting the toy with a garden hose, children can then slide down the plastic sheet. The original Slip N Slide was created by Wham-O.
