Primary color mixing experiment with coffee filter snowflakes and heart-flakes

I love the color wheel and love seeing what colors you get from mixing paints. This was the perfect project to let Sophia experience the wonder.

This is a project I’ve been dying to try out with the liquid watercolors… you can substitute food coloring or even cake watercolors (you would need paint brushes for this option).

What you will need:

  • Liquid watercolors/food coloring
  • Cups for your watercolors
  • Pipettes
  • Coffee filters
  • Scissors
  • Wet wipes (for clean up)
  • Baking sheet
  • Tinfoil
  • Oven (not necessary)

Flatten, fold and cut out your snowflakes to your liking from the coffee filters.

I cut out 3 filters on top of each other in the heart shape and 4 together on the snow flake. For painting them I placed them on the baking pan 2 on top of each other (I didn’t think Sophia would have the patience to repeat the process 7 times and 4 seemed just right). One of the heart ones was on the pan singly (for the math minded 😉 )

I diluted the liquid watercolors quite a bit. I put about a 1/4 inch of water on the bottom of the cups and then added the paint to my liking.

Below is a time lapse video of Sophia having fun squirting and mixing the paints together.

All done with the first set.

The second set got more brown as she liked putting all the paint in one spot.

I placed them in the oven to dry, with just the oven light turned on for a small source of heat. I wanted the end results to be as vibrant in color as possible, so I wanted all the paint to dry on to the coffee filters. It took about 5 hours for the hearts to fully dry.

TIP: You can remove the snowflakes off the cookie sheets and set to dry on a dry surface. Note that the colors will not be as bright if you do this though.

It’s crazy how much less vibrant the colors are after they dry.

TIP: If you want to get some of the wrinkles out, place them in side a book. Each snowflake on their own separate page and then place a weight (or more books on top). Let sit over night.

Love how these snowflakes turned out

Once dry they are ready to tape to your windows.
