Most kids are used to mixing colors with paints or play dough, but have your children had the chance to try separating color mixtures? In this science experiment for kids we’ll be exploring chromatography (separating mixtures). We’ll use coffee filters to separate the various pigments in markers to see how each color was created!

Materials for Science Experiment & Butterfly Craft
- Non permanent markers (Over the years I’ve found Mr. Sketch markers work the best in this experiment.)
- White coffee filters
- Pencil
- Cups of water
- Black pipe cleaners
- String
- Scissors
Procedure to Chromatography Science Experiment
1. Choose one marker to experiment with first. (Hint~ black and brown are the most exciting!)
2. Take one coffee filter. Put it on a newspaper or some kind of material to protect your table. Draw a thick circle around the center of the coffee filter where the ridged part meets the flat center. Use a pencil to write the color of the marker being used right in the center. (You’ll want to know what the original color was being used, and the pencil won’t smear and will remain intact after the experiment.)
3. Fold the coffee filter in half and then in half again, resulting in a cone shape.
4. Get a short glass of water. Pull apart the cone shaped coffee filter so it balances right on the glass with the tip of the cone just touching the water. (Be sure NOT to let the marker circle go in the water, just the uncolored tip of the coffee filter cone.)
5. Let it sit and watch what happens as the water begins to flow up the paper.
6. Repeat with different colored markers. Here are ours starting out…
… and just about done!
7. After the water has reached the outer edge of the coffee filter, place it on a newspaper to dry. (Lucy and her friend enjoyed illustrating their predictions on paper while waiting for each color to finish separating.)
8. Once the coffee filters are dry you can observe the results.
Directions for Using Coffee Filters to Make the Butterfly Craft
1. Cut your black pipe cleaners in half.
2. Take one coffee filter and scrunch it up in the middle.
3. Wrap a black pipe cleaner around the center.
4. Shape the ends to form antennae.
5. Tie a string to the center and hang!
Watch it in action!
Question to Spark More Curiosity & Critical Thinking
What colors do you see? How many colors do you see? Which one do you find most interesting? Why?
Don’t forget to follow your child’s lead and let your him/her explore some more! Lucy and her friend wanted to try all the different colors to see if they’d separate. They wondered if the marker would separate on just regular paper and came up with a way to try it out.
After the experiment was complete, the thinking continued! Lucy’s friend was determined to have the butterflies balance just right when tied on the string. We tried different placements of the string to see the different ways we could get the butterflies to hang.

Laura says
March 4, 2013 at 2:52 amI remember doing this ‘properly’ at school – Your way looks much more fun! And let’s face it we learn much better when we are having fun… Thanks, I will try this with my little ones 🙂
Chelsey says
March 4, 2013 at 9:16 pmThanks, Laura! The kids did have lots of fun! Hope you all enjoy it!

March 4, 2013 at 2:26 pmI love this experience. Lucy and her friend look so relaxed and I can see the complicity between them… seem to have the world’s most animated conversation. I bought a few months ago thinking filters do it but must be forgotten in some drawer. Thanks for reminding me.
Chelsey says
March 4, 2013 at 9:15 pmThanks, Angaleta! Coffee filters= tons of possibilities!

Melissa says
April 23, 2014 at 12:09 pmHi. This is such a cool idea. I have a question on repeating the process. Do you take the filter out of the each time you draw a different color circle or do you draw all the colors first then place in the glass jar? Thanks-Melissa
Melissa says
April 23, 2014 at 12:11 pm*out of the water each time…..
Chelsey says
April 24, 2014 at 7:49 amThanks, Melissa! We drew one circle (only one color) per coffee filter. So one coffee filter had a black circle, one coffee filter had a brown circle etc. After drawing all the circles on the coffee filters, we placed each one in its own glass of water to watch the colors separate! Hope that helps!
Laura says
April 24, 2014 at 12:13 pmIt looks like this experiment worked well for others, so it was disappointing to me that ours turned out the way it did. The water did not want to travel up our coffee filters very well and the little it did, it simply spread a bit of the same color around but did not really separate it. Some of the colors actually got into the water and colored our water the original colors, too, and then we were left with white filters. 🙁
Chelsey says
April 24, 2014 at 10:14 pmSo sorry to hear it didn’t work, Laura. What brand of markers did you use? We always have the best results with Mr. Sketch.
Rachel says
April 29, 2014 at 3:06 pmI can’t wait to try this with my daughter! I did have a question before we dive in head first: How long does it take from start to finish? I was thinking it would be a darling birthday party activity if it doesn’t take too long.
Chelsey says
April 29, 2014 at 5:06 pmHi Rachel! I’d say we let it sit in the water about 20 minutes or so, and the coffee filters should dry fairly quickly if you place them on newspaper to dry or out in the sun! Hope you all have fun!
Lyla G says
January 27, 2015 at 4:18 pmWe tried this today but I only had brown coffee filters and it was a complete bust : (. I did use Mr. Sketch markers but the circles just made the water colored. I tried with Crayola markers too and same thing. My daughter didn’t mind since she was excited to mix the colored water but I guess there is really something different about the brown filters.
Chelsey says
January 27, 2015 at 4:39 pmThanks for sharing, Lyla. Interesting. I haven’t tried it with the brown filters, but we have some at home so I think I may give it a shot and see what my results are. So sorry it didn’t work out, but glad your little one still had fun! I’ll keep you posted on my results with the brown filters!
Chelsey says
January 27, 2015 at 4:47 pmJust tried a brown filter, and it worked for us. You want to make sure only the tip of the cone is in the water, not any of the actual marker circle. Do you think that could have been the problem? I’m going to edit the directions above to be a bit more clear on that. Thanks again so much for sharing!
Lyla G says
January 28, 2015 at 6:49 pmYES! That was the problem! We tried it again tonight and it worked perfectly. I guess I read too fast and my 5-year old was a little overexcited to dunk them. Thanks so much for responding. Looking forward to trying all your other fun projects.
Ashley says
October 11, 2015 at 5:15 pmHello!
So I’m an aspiring teacher, and I am doing a practicum at school with preschoolers. I don’t have a lot of time to do some activities. All in all how long do you think this experiment takes? The water absorbing and the drying portions especially?
Thank you!
Ashley
Chelsey says
October 12, 2015 at 9:27 amHi Ashley~ I’d say the water takes about 20-30 minutes to soak completely through the coffee filter. If you place the coffee filters on newspaper to dry after the color separates, they will dry fairly quickly- maybe another 20 minutes. If you can place them in the sun, it will speed it up even more. 🙂
MaggieLouize says
March 28, 2016 at 4:06 pmAwesome idea! Question tho: the Mr. Sketch markers work best.. the link is for scented markers. Are these the ones you used, or the non scented ones??
Chelsey says
March 28, 2016 at 4:57 pmThank you! We used the scented markers! 🙂

April 26, 2017 at 11:20 amWhat a wonderful learning activity. I am featuring this with a link on my blog.
Sophie says
September 21, 2018 at 6:05 amI want to do this for my daughter’s science project, but i can’t find coffee filters that looks like that here. Will it works the same if i use papercups?
Betty Goodwin says
December 7, 2018 at 7:02 amThese are so nice and gentle looking. I already have an idea where I’d like to put mine.
