The motion of the upper free surface of a liquid column released from the rest in a vertical conical container is analyzed theoretically and experimentally. An inviscid one dimensional model for a weakly increasing cross section in vertical tubes describes how the recently reported super free fall of liquids occurs in liquids of very low viscosity. Experiments show that the inviscid one dimensional model developed here agrees with theoretical results.
