What Kids Learn From This STEAM Activity
In the STEAM Activity, Water Down a String, kids learn water likes to stick together and to the other materials. They observe that when water is poured onto a string, it doesn’t just fall straight down like we might expect. Instead, it sticks to the string and flows along it, moving from a higher cup to a lower cup. This happens because of a combination of forces, including cohesion (water molecules sticking to each other) and adhesion (water molecules sticking to the string’s material). This experiment teaches kids that water can behave in interesting ways due to these forces, even defying gravity a bit. This experiment is like a mini water ride right in front of their eyes!

How to Do the STEAM Activity Water Down a String Experiment
Variations & Challenges
- Try using liquids other than water, like colored water or juice, and see if they flow down the string in the same way.
- Use different types of strings, like a shoelace or a piece of yarn, to see if the thickness of the string affects how the liquid flows.
- Use two strings side by side and pour water down one string while leaving the other dry. Compare how the water behaves in both strings.
