The liquids employed in all experiments had a viscosity higher than 3 Pa.s; these included commercially available epoxy resins (Pattex, 5-minute), polydimethylsiloxane (Dow Corning), polyglycerolpolyricinoleate (PGPR, ILshinwells co., Ltd), silicone oils (Aladdin). To facilitate observation of the interface, two methanol-soluble dyes, Oil red O (Sigma-Aldrich) and Malachite Green (Aladdin), were added to silicone oils for visualization under optical microscopy respectively.

The viscosities of the liquids used in our experiments were measured using a rheometer (Brookfield, R/S series) and were listed and summarized (See Fig. S9 and Table S10 in Supplementary information). All the viscous liquids we used in this manuscript were Newtonian, and thus non-Newtonian effects were not taken in account.
