Relation between the total splashing volume ε and the splashing threshold K. Different symbols represent the experimental data using different kinds of liquid. The black dotted line shows the fitting curve using ε ~ (K − K0)2 (R-squared value = 0.74), and the red solid line shows the fitting curve using ε ~ (K − K0)3 (R-squared value = 0.81), which is more reasonable for the correlation
