  Raised menisci around small discs positioned to pull up a water-air interface
provide a well controllable experimental setup capable of reproducing much of
the rich phenomenology of gravitational lensing (or microlensing events) by
$n$-body clusters. Results are shown for single, binary and triple mass lenses.
The scheme represents a versatile testbench for the (astro)physics of general
relativity's gravitational lens effects, including high multiplicity imaging of
extended sources.
