Try to make a pin or a needle remain on a water surface as shown in the figure above. (Tip: To make a pin "float", place the pin on a fork and slowly lower it into the water body.)

Study the object on the surface of the water.  At first it would appear that the pin, which has a higher density than water, is floating on the surface. Careful observation will show that the surface of the water is depressed around the pin.  The vertical component of the force resulting from surface tension along the points of contact of the water surface with the pin supports its weight.
