Over time, anyone involved in the computer racket will accumulate a number
of keyboards whose keys stick or otherwise don't key in the manner required.
Somehow, you can never quite bring yourself to just drop one in a trashbucket;
they seem somehow destined for a different fate.
The experimental methodology involved three keyboards, with the ends of
their cords tied and ducttaped together, in hopes that they'd gyrate
around each other in midair.
The first half of the experiment proved quite satisfactorily that the
keyboards are in fact subject to the anticipated 9.8 metres per second
squared earthward acceleration.
Further research is required; it looks like it might be possible to skip
a keyboard across the water, given a sufficiently low angle of incidence
and possibly some spin.
The subsequent phase of the experiment showed that although the physical
displacement of a keyboard, measured in millilitres, was initially greater
than its weight in grams, there is sufficent unsealed empty space within
the unit for this relationship to reverse itself within seconds after
immersion.
It also turns out that the keys are really not attached all that well.
It proved necessary to go out in a canoe and collect various floating
keycaps. Here I've got a spacebar.
An assortment of keys in the bottom of the canoe.
The keyboards return from the deep.
