Science Magic You Can Do-Water Surface Tension
Показать описание
Surface tension is a phenomenon in which the surface of a liquid, where the liquid is in contact with gas, acts like a thin elastic sheet. Explore how surface tension works by dropping pennies into a glass full of water until the water extends well over the lip of the glass without spilling. Float a paperclip on water using the properties of surface tension. Then, use soap to eliminate surface tension in a visually startling way.
