Figure 7.
The image depicts three sequential frames illustrating a process in which a hand operates a spray device suspended from above, releasing thin strands of material. The first frame shows the device positioned over a surface with a ring and a container placed below. The second frame captures the moment when the strands begin to form a curtain-like appearance. The focus remains on the interaction between the hand, the spray device, and the material falling towards the surface, where a mixture of powder and a circular ring is located, suggesting a controlled environment for layering or coating. The surroundings include various objects, indicating a workspace setting.The effect of the diffuser mesh position on the rain uniformity: no mesh (left), high mesh (centre), and low mesh (right)
