(color online) Comparison among trajectories of different-temperature spheres falling into different-temperature water: (a) T_w = 25 °C and T_s = 25 °C; (b) T_w = 95 °C and T_s = 500 °C; (c) T_w = 25 °C and T_s = 400 °C. In each panel, different symbols represent different independent trials for the same water and sphere temperature.
