Water Can Run Uphill
Everyone knows that water can’t flow uphill…unless I get involved. Mix a small amount of polyethylene oxide, a polymer, with water and it forms a thick, slippery, gooey, mucous-like gel. Oh, the visual imagery! When the gel is poured back and forth between two beakers, the gel mysteriously pulls from the higher held beaker to the lower one. Maybe water can flow uphill.
