Capillary Action for Kids
Kids are naturally curious about the world around them. They ask lots of questions and perform their own experiments. Just look at a toddler who decides to blow into his milk to see what will happen. It sometimes takes them a lot of trial and error, but eventually they realize it will bubble up over the top of the glass and make a mess. Preschoolers stomp in water or mud puddles to see what will happen and then continue to jump more as they realize it makes things spray up and make a mess. Kindergartner find a worm, ladybug, spider, or other insect and follow it around the yard, pick it up and observe it.
Children are little scientists. It is us adults that teach them to stop exploring and trying new things when we harshly yell stop blowing bubbles in your milk instead of saying, it made a mess when you blew bubbles in your milk didn’t it. Let’s try a different activity. They need to know guidelines, methods to explore around them so they can investigate without causing mayhem or large messes.

Walking water experiment
Walking water science experiment
Capillary action is the process in which a liquid moves up something solid, like a tube or into a material with a lot of small holes. This happens when 3 forces called cohesion, adhesion, and surface tension work together. Water molecules are considered cohesive (sticky to each other) and they adhere (stick) to the paper towel. As one water molecule moves up the paper towel it pulls the other molecules with it. The molecules pull each other along like a drawstring.
