And it turns out that this spherical shape has the highest volume to surface area ratio and it creates an optimal arrangement of molecules that creates a maximum amount of hydrogen bonds. And that's exactly why the water forms that spherical shape in the first place. So pure water has a high surface tension. Now, in diagram B, when we take our pipette that contains our detergent and we release a small amount onto the water, that water breaks its spherical shape, it collapses and spreads out. It flattens out along the surface of the table. The question is why?
