Mercury doesn't "flow" that fast. BUT, one may consider a "3rd" pendulum"
using the capillary as a pendulum.. hmmm a sorta torque tube having 'spring"
characteristics..
Naw! too lascivious..

One way might be to construct the opposing weights
essentially as "containers" which are filled with a
conductive liquid such as mercury or NaK.
The two are connected to each other with a hollow
capillary tube (suspended so as not to interfere) so
that a few milligrams of mass, over and above the
magic ratio of three, can be shuttled back and forth
on command in milliseconds using solid state (MHD)
pumping, controlled by a CPU.
