Varun and I are continuing with our science explorations. First we did our volcanoes and then we watched what happens to the dishwater tablets. Next up, it was our turn to watch water walk.
Yup, when I read the title of Walking Water Science Experiment on Pinterest, I wanted to see it action right away. We set to it right away.
First up, we got out 4 glasses of water and added food color to it. Varun stirred it all up.
Then I folded paper napkins into thirds (along the length) and we folded and added them to the glasses. See image below.
I asked Varun to touch the top of the napkins. They were dry.
As water started “walking up” the napkins ( ala capillary action), the tops got damp. When he touched them a few minutes later they were damp. And later they got the color.
He was excited to show me how the color’s met towards the top of the napkins. We used tall glasses so this kindda took hours. It was a test of patience. But with shorter glasses and higher water levels it could be within an hour.
Next up was another variation of seeing water walking.
We stared with 2 glasses full of water. One was colored blue and other yellow. A third empty glass was placed in between them.I folded paper napkins and kept them such that one end dipped in colored water and other end rested in empty glass.
Over time, water rose up the napkins and collected in the empty glass in the middle. The empty glass now had green water 🙂
An excellent way to showcase color theory alongside some science!
I think Varun is too young to understand “capillary action” or at least I wasn’t sure how to explain it to him but I think when he learns the concept later on he will remember these fun experiments. It was fun for us grown up’s too : )
Would you try this? What else would you recommend we try as we explore Science at home?
