As shown in Figure , both the Kamloops and the Kelowna samples shattered at 30% RH and the shards did not show any signs of flowing. Experiments were not conducted at drier conditions, because lowering the RH can only lead to the same or even higher viscosities, and therefore the same shattering result. At 40% RH, the particles also shattered with no signs of flow. For the Kamloops sample, the poke in the center of the droplet did not cause cracks to extend all the way to the outer phase, so another poke was made in the outer phase as quickly as possible (near the top of the particle in Figure , second row), and this poke caused clear cracks in the outer phase.
