Detailed explanation-1: -The high surface tension helps the paper clip-with much higher density-float on the water. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.

Detailed explanation-2: -An object floats when the buoyant force is large enough to counter the object’s weight. So a large hollow object might float because large means more water displaced – so more buoyant force – and hollow means relatively little weight. A small solid object might not float, however.

Detailed explanation-3: -Surface tension allows water to hold up materials heavier and denser than itself. For example, the high surface tension of water enables a paperclip to float on the surface of water, and also allows some insects to walk on the surface of water.

Detailed explanation-4: -When the tissue is submerged, the paper clip remains on top of the water because of the surface tension of the water. Adding soap reduces the surface tension of water. Soap, a surfactant, will cause the paper clip to sink.
