For particles that formed an approximately half-torus geometry after poking, a half-torus geometry was used in the simulations. Upper and lower limits for the particle's surface tension, contact angle, and Navier slip length (Table ) were used as input to the simulation along with the particle's size, density, the hole's inner diameter, and experimental flow time τ exp,flow . Simulations were run with a range of viscosities. The viscosities that gave the best fit to the experimental data were determined by comparing the simulated final inner diameter to the experimental final inner diameter of the half-torus geometry. The upper bound and lower bound viscosities were calculated using conservative upper and lower limits to the surface tension, contact angle, and Navier slip length in the simulations (Table ).
