“Walking Water” is a fun and simple science project that helps kids understand two important properties of water: adhesion and cohesion.
Here’s how it works:
Adhesion: Water also likes to stick to other things, like paper towels or string. This is what helps water move or “walk” from one place to another.
Cohesion: Water molecules like to stick together. This is what makes water form droplets. It’s like a team of water molecules holding hands and staying close.
How the experiment works:
You set up two cups: one with water and one empty. You connect them using a paper towel or string.
The water in the filled cup starts moving up the paper towel due to adhesion (water sticking to the towel).
As the water climbs up, more water molecules get pulled along because of cohesion (water molecules sticking to each other).
Eventually, the water reaches the empty cup and starts filling it up! It looks like the water is walking from one cup to another.
This simple experiment is a great way for kids to see how water moves and behaves!
