What is a beading effect?

The beading effect refers to a visual phenomenon where small, rounded droplets or beads of liquid form on a surface instead of spreading out evenly. This effect occurs due to surface tension and the interaction between the liquid and the surface's properties, such as hydrophobicity or hydrophilicity. In various contexts, such as Photography or materials science, the beading effect can influence aesthetics and functionality, affecting how liquids behave on different surfaces.
