The paper clip is on the water but is not floating like a boat which is less dense than water. The paper clip is more dense than water but can rest on the surface of the water because of the water's ...

Bonding over the science of Surface Tension! Why do some things float in water while others sink? The Crew’s depth of knowledge goes WAY below the surface, as they learn all about the molecular bonds ...

THE reply by Mr. N. K. Adam, in NATURE of September 26, p. 464, to my note on the cause of surface tension, contains a very great deal with which I heartily agree. His method of calculating the shape ...
