The Sci Guys: Science at Home - SE3 - EP4: Water Glass Surface Tension - Surface Tension of Water

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.

    I've been trying to answer this question for years. If you put water in a glass but don't fill it all the way up to the top, is there a difference between the surface tension in the center versus the edge?

    Not a word about the hyfrogen bonding which helps the water molecules stick together much stronger than some other liquids? Hydrogen bonding adds a lot to the surface tension. Also you can do this experiment by dropping water droplets onto a penny. I could only get 11 drops back when we did this experiment in grade school.

    ***** We didn't mention hydrogen bonding because our average audience doesn't typically learn that concept till much later on.This episode was made as an introduction to surface tension, we have plans to do the droplets of liquids into pennies. In that episode we would expand on the concepts and explain why water is stronger than other liquids that we test on the pennies.

    Food for thought From this experiment we can learn that we should always drink water from spherical shape pot. Because surface tension very low. When you drink water from any spherical shape storage object, water surface will be less tense and your intestine will remain open for good digestion. Benefit of low tension water is not visible right away but in long run it does help your health. Calculation lets take cylinder shape glass of water, and round shape water glass (we can ignore slight flat bottom of spherical glass) area of object in cm2 spherical shape glass radius is 5 cm so area will be π * r * r = 78.54 cm2 area of cylinder shape glass with radius 2 cm and height 5 cm ( 2*π*r*h+2*π*r*2) = 87.96cm2 lets spherical volume in cm3 for each object spherical shape object volume (4/3πr3) = 523.6 cm3 cylinder shape object volume (πr2h) = 62.83 cm3 which is very less then spherical object. So there are way more water molecules are in touch with surface in regular glass of water then water stored in spherical shape glass.
