Easy Saturday Science Project: Walking Water

I saw this on Pinterest, and it was just a quick science project we could have going during the day, so we gave it a shot!

Walking Water!

It’s pretty (ridiculously) easy:  You need 3 cups, 2 paper towels and some food coloring.  The goal is to watch the water “walk” up the paper towels and transfer into the middle cup.

caveat: This projects takes forever.  For. Ev. Er.  So, it’s not only a lesson in physics, but also one in patience.

1) Take the cups and put them next to each other.  Put a few drops of food coloring in the outside cups and stir in some water.  We did yellow and blue so we could make green!

2) This is after about half an hour.  It’s fun to watch the water walking across the paper towels.  You’ll find yourself saying things like: “I’m so glad this is working.”

3) This is after about 2 hours.  It takes a while.

4) This is after 3 hours…we are finally starting to get some green in the middle!

5) This is after a couple hours…maybe 5.  I stopped checking exactly a few hours ago. I’m just glad we’re getting a puddle in the middle cup at this point.

6) I took this picture before I went to bed at 11pm, so it has been about 12 hours by now.

7) This is when I woke up…I think this is all we’re going to get.  The blue transferred itself over more than the yellow for some reason, but we have a nice emerald green in the middle!  IMG_8017

 

Anyway, this is a fun project to do with the kids  🙂  Here are some lesson sheets on diffusion vs. osmosis if you want to ramp it up!
