Critical pressure (PC) for different gels obtained from cavitation rheology experiments. The micrographs illustrate the cavity growth at the tip of the needle. The experiments were conducted at 22 °C and 72 h after addition of water. The inner radius of the needle is ≈156 μm. The scale bar represents 2 mm.
