Welcome to episode four, season three of science at home. In this episode we add pennies into a full glass of water to show how surface tension will create a convex dome of water that rises above the rim of the glass. Surface tension is generated by cohesion and keeps an elastic tension between all the molecules in a liquid. The water has one of the highest surface tension. At the end of the episode you will be able to explain surface tension and you will be able to demonstrate the dome created by the surface tension of water.
