CAMPHOR IN WATER

(No longer Done)




EQUIPMENT
    redball.gif (326 bytes) Camphor

NARRATIVE
            The surface tension at different points on a non-uniform piece of camphor floating on water is different.

            Place a dish of clean water on the overhead projector. Shave some camphor into the water. It will move about rapidly because of unbalanced surface tension.
