Answer 2

Take a bloating paper and keep a small needle on top of it. Fill a small jar with water and keep paper on the top surface of water. Avoid any fan in the area or vibrations or movement of jar. After some time paper will sink after absorbing water but needle will keep on floating untill the water surface is disturbed. This is due to surface tension. Needle is heavier than water but will float.
Second condition is when u see a human swim. Even if overall weight of person is higher that water of his equivalent volume he floats. The reason is because he displaces water by his hands and legs. The weight of displaced water is resposnsible for his floating. Similarly other floating things like fishes and all.
