Title:  Continual skipping on water

Abstract:  Skipping stones at the beach is familiar to many - throwing
the stone into the water in such a way that it bounces several times
before eventually sinking.  This is due to the inertia of the water
which provides a sufficient vertical force to overcome the stone's
weight, and has been reasonably well described by simple models.  I will
describe details of experiments designed to replicate this effect, but
with a constant horizontal velocity imposed on the stone (or inclined
plane, as it is the experiment - like a water ski) - in this case it can
continue bouncing indefinitely.  I will discuss why this behaviour
cannot be explained by the simple models, and suggest some alternative
shallow water models which can explain `continual skipping'.
