(a) Top drop velocity Vd as a function of the bubble radius Rb in water, champagne at 20 °C and in the three hydro-alcoholic solutions (i)–(iii). The dashed line curves are the best fits of the experimental values of the drop velocity. (b) Top drop radius as a function of bubble radius in water, champagne and in the three hydro-alcoholic solutions (i)–(iii). The dashed lines are the best fits of the four series of data. The four snapshots display the jet and jet drops for each solution, showing that the more viscous the solution, the smaller the top drop.
