Traveling Colors- An Experiment in Absorption, Dispersion, and Color Mixing

The paper towel absorption was such an interesting science experiment we decided to try another paper towel experiment

We filled 3 glasses equally with 1/2 cup of water and liquid water colors

We then put our paper towels in folded several times over to create strips.

We watched as the liquid moved up the paper towels

And into the empty cups between each glass with liquid

The empty glasses started to fill with liquid from both glasses next to it

Kaia tried keeping track of which colors moved the fastest

By the next day the glasses that were empty were now even with the ones that were full

We now had a green cup, orange cup, and purple cup.


  1. This is neat and it would be fun to try on a t-shirt and see what happens. I bet it would turn out cool!

  2. Question: How long did it take the colors to mix together?

      The colors start traveling instantly. The colors don’t actually mix for a few hours though. We left ours overnight
