This past week I decided to get my 2.5-year-old involved in a little science experiment. She loves coloring and crafting, so I decided to take a twist on her favorite past-time and "break down" the concept of color. We set out to separate the colors found in our washable markers and find out what colors are combined to create our favorite hues using a technique called "Chromatography."
For this experiment we gathered a few items:
- Washable Markers
- Drinking cup
- Coffee filter
- Clothes Pins (optional, but what cloth diapering parent doesn't have these?)
Now we waited. It takes about 30 minutes for water to draw up the filter paper and drag the marker color along with it. As the water crept up the filter paper, it pulled the different hues in the marker color at different rates and we began to see two colors separating from each color: Purple (red and blue), and Green (yellow and blue).
