"A recent experiment conducted by physicists at University of Bristol
in the United Kingdom has shown that liquid drops can defy gravity.
Droplets of liquid on an inclined plate that is shaken up and down can
travel uphill rather than sliding down. In fact, if the plate vibrates
at the right rate, the droplets will always travel counter-intuitively
up the incline."

xxein:  I can do the same with sand on a Teflon sheet.  What's your
point besides that you mistakenly think there is some secret here?

There is nothing in that article or experiment that implies anything is
wrong in relativity. They simply constructed a rather inefficient method
of lifting liquid droplets against gravity. The fact that I can pick up
a stone from the ground and raise it over my head does not "defy"
gravity in any sense; neither do these droplets.

i suspect you are about ta do tha same mistakes
xx...comcast do, and not sensing tha issue here

same conditions and free body forces
acting in all x, y and z directions

whay should tha droplet go upwards and
not downwards or at least stay still
while he is in equilibrum?

i dident read tha article, but i think
i know tha answer, maybe you dont do
