(a–c) Optical images showing that NG2-1.5 samples are too brittle to sustain compression (a, Supplementary Movie 1), slicing with a blade (b) or elongation (c). (d–i) Optical images showing that NSG (NSG20-1.5-0.5C) samples are very elastic to sustain a high compression (d, Supplementary Movie 2), resist slicing with a blade (e, Supplementary Movie 3), and withstand high level of deformations such as bending (f), twisting (g), knotting (h) and extensive stretching (i). T=25 °C.
