Surface tension is a force—a force powerful enough to prevent water from spilling out of an open jar when it is turned upsidedown! A fine mesh screen hidden inside the lid of the jar provides hundreds of tiny surface tension “membranes” that, in addition to air pressure, will support the weight of the water.
