Under the right conditions, it is possible, due to surface tension, to have metal objects float on water. consider placing a short length of a small diameter steel (sp. wt.=510 lb/ft3) rod on a surface of water. what is the maximum diameter, dmax, that the rod can have before it will sink? assume that the surface tension forces act vertically upward. note: a standard paper clip has a diameter of 0.036 in. partially unfold a paper clip and see if you can get it to float on water. do the results of this experiment support your analysis?
