I use a box fan to help dry the dishes in the dishwasher. Recently I mistakenly pointed the fan away from the dishes instead of toward them. This appears to be faster and more effective than my normal method. Why?

    Blowing into an enclosed space is chaotic, the fan has to push against air currents being deflected. Blowing into an open space (aka sucking out of you dishwasher) is much more orderly, the fan can simply pull the air out and there are much fewer air currents running orthogonal.

    This is as far as my very basic knowledge goes here. You can try this effect by exhaling and inhaling air through a barely open mouth or a straw.

    EDIT: On a related note, never “blow” during fellatio.
