Video S1: Real-time absorption of water stained in blue into the protein sponge structure leading to swelling and softening, Video S2: Real-time absorption of silicon oil into the protein sponge structure, remaining stiff and brittle, Video S3: Real-time absorption of ethanol stained with nile red into the protein sponge structure, remaining stiff and brittle, Video S4: Rotation of the vol-ume-representation of the binarized μ-CT images showing the protein sponge structure (grey) wetted by decane (red), Video S5: Build-up of the volume-representation of the binarized μ-CT images from bottom to top with the protein sponge structure in grey and decane in red showing that some pores are completely filled with decane while others are only wetted along the solid surfaces.
