A formal equivalence between the motion of an inviscid fluid in a capillary tube and the Friedmann-Robertson-Walker cosmological equations is discussed. Similarly to the case of “sonic black holes" or “black-hole analogs", largely discussed in the recent literature, it is hoped that this analogy may inspire a class of capillary-filling experiments reproducing simple cosmological scenarios in terrestrial laboratories.
