//Surface Tension//
These objects "float" on top of the water because of a physics property called surface tension. Surface tension enables more dense objects, such as the paper clip or flower petals, to "float" of less dense substances, such as water. The water molecules are attracted to each other, staying together. When another object comes in contact with this "army" of water molecules, it takes a certain amount of energy to break through the surface. If the object on top of the water does not have enough energy to break through the surface, it will float on top of the water, as these flower petals and this paper clip do.
