In their new Letter, Deblais et al. use experiments, theory, and simulations to study the very first moments of drop coalescence. In drop-drop and drop-bath configurations, the authors show the key role played by surrounding gas and van der Waals forces

📢 in @JFluidMech (bit.ly/3QuxMgE) on how viscosity alters drop-impact forces. With Bin Zhang, Cunjing Lv, & @detlef_lohse. The first and second force peaks emerge from distinct flow mechanisms—one at impact, another at take-off. @poftwente bit.ly/4gUvD8P
