OF the various methods of determining surface tension of liquids, the method of ripples is free from all surface influences. Lord Rayleigh, Dorsey, Grünmach, Kalähne and others have determined the ...

Introduction Have you ever noticed on a rainy day how water forms droplets on a window? Why does it do that instead of spreading out evenly over the whole surface? You might not guess it but this ...

Demonstrates basic principles of water, including surface tension, pressure, and buoyancy. It shows how water can hold more than its brim due to surface tension, how pressure increases with depth, and ...

Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...

Dyne Testing, an Intertronics brand, presents the Sigma 702 Force Tensiometer from Biolin Scientific, a standalone instrument for precise surface tension and interfacial tension measurement. The Sigma ...

Propelled by chemical changes in surface tension, microrobots surfing across fluid interfaces lead researchers to new ideas. Spend an afternoon by a creek in the woods, and you’re likely to notice ...

Our readers agree that the world would be a very different place if water displayed no surface tension, making life on Earth ...

Foaming is nature’s way of making beer even more delicious. Yet not all foams are understood because they don’t seem to obey the model that explains most of the rest. Understanding these atypical ...
