Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to, external forces like gravity. In this walking water experiment, liquid uses the ...

PITTSBURGH (KDKA) -- Candles are neat, calming to some and full of science. They are made of wax and a wick which seems pretty simple. Once you light the candle, the wick burns. As the wick burns, it ...

This experiment demonstrates how plants transport water and nutrients through their stems. You'll witness the fascinating process of capillary action as white flowers transform into colorful blooms, ...

Mechanical engineers have devised a technique of 'crystal capillary origami' where salt crystals spontaneously encapsulate liquid droplets. The process offers a new method of nanostructure ...

This experiment demonstrates capillary action - how water can climb up through tiny spaces in materials. You'll create a beautiful rainbow pattern while learning about the same process that helps ...
