    I was running a bath and had a thought.

    If i ran a bath so that
    The bath is totally filled to the brim and then left so that the water was perfectly still.
    I then add another drop of water to the bath. does this water droplet mix with the water in the bath, or does surface tension or other factors mean the water droplet runs off the surface and over the side not mixing with the bath water at all?


    everything is mathematical.

    Surface tension negation only applies to foreign elements.
    Of all the wonders in the universe, none is likely more fascinating and complicated than human nature.

    "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe."

    "Great spirits have always found violent opposition from mediocrities. The latter cannot understand it when a man does not thoughtlessly submit to hereditary prejudices but honestly and courageously uses his intelligence"

    water is a polar molecule. wich atracts other polar molecules. i think it is a polar molecule because the oxygen atom has 2 hydrogen atoms at each of its poles.
    In life it is not the destination that matters,but the journey there.

    Sorry my first reply was so brief. I didn't mean to be flippant.

    Surface tension exists because there is an imbalance of electrostatic forces (van der Waals) on the water molecules immediately above and below the surface. As the new drop touches the surface, or perhaps at the instance just prior to the touch, the imbalance vanishes. At the area of contact the forces that create surface tension no longer exist. The arriving molecules feel the attractive (cohesive) forces of the main body and are drawn into it.

    Good question.
