Figure 4. Artificially reversed egg rotation.

Figure 4

(A) A schematic diagram of the oil injection to float the eggs. The eggs were floated near an oil-water interface, where the no-slip boundary conditions could be applicable due to the high viscosity of oil. (B) A snapshot from the Supplemental Movie. Observation, together with the egg rotation speed, taken as positive for counterclockwise rotation when viewed from the top (Supplemental Movie 6). The average rotation was −3.12 rpm (clockwise rotation).
