Caption: The evolution of the transient force of a water drop impacting on the superhydrophobic surface at a moderate Weber number $\Wen = 40$ (corresponding to $D_0 = 2.05\,\si{\milli\meter}$ and $V_0 = 1.20\,\si{\meter}/\si{\second}$), with simultaneous drop geometry recorded experimentally at 10,000 fps with the exposure time of 1/20,000 s. The left part of the numerical video shows the dimensionless local viscous dissipation rates on a $\log_{10}$ scale, and the right part shows the velocity field magnitude normalized with the impact velocity.
