Drip versions
a tap
drips
landing near the inside edge
of a metal bowl suspended in mid air
which goes "ting" when a drip landsthe drips flow down into the bowl
spreading out as they go
from sharp spikes of mass (impulse train)
becoming overlapping humps (near-Gaussian)
and eventually flatthe bowl has a small hole in the middle
when enough liquid has accumulated
from the flow of the drips into the bowl
to overcome surface tension
the liquid drips through the holeunderneath the hole in the bowl
is another bowl with a hole
which goes "ting" when a drip lands
near its inside edgethis goes on for some time
each bowl larger than the last
with a deeper "ting"the final bowl drips into a plant pot
it grows and flowers
