The Sci Guys: Science at Home - Comparing Surface Tension Experiment - Penny Surface Tension
Share:
Welcome to science at home episode seven, season three. In this episode we compare the surface tension of multiple liquids by dripping drops of a liquid on a pennies surface. Surface tension can vary a lot between liquids and the bigger the droplet grows before it bursts, the stronger a liquids surface tension is. By the end of this video you will be able to describe what surface tension is, how it helps to create a dome of liquid and why the droplets eventually burst.
