Homemade Watercolors for Kids

Did you know you can make homemade watercolors? I had no idea until a few months ago and the ingredients will shock you.

This watercolor recipe uses items you already have in your kitchen and it’s easy to make.

It is a great project to let the kids help with. They get to measure, create colors and watch science happen before their eyes.

Let me show you how to make this.

You Will Need:

  • 1/2 cup baking soda
  • 1/4 cup white vinegar
  • 1 tsp. light corn syrup
  • 4 TBS corn starch
  • a couple of toothpicks
  • food coloring
  • ice cube tray (I like the ones with lids)

Gather up your supplies.

Mix the baking soda and vinegar together in a bowl.

Then add the corn syrup. Continue to stir and mix well.

Then add the corn starch. Make sure everything is mixed to a nice liquid with no clumps.

Next, use a measuring spoon to put a small scoop of the mixture into each ice cube rectangle.

This recipe should give you enough to make 12 colors.

Next let the kids create colors.

Use toothpicks to mix the food colors into the cornstarch/baking soda base.

Now let it dry. It will take 24-48 hours.

I like the ice trays with the lids on them. Mine is old and from back in my days of selling Tupperware. Now, other brands make them. Search on Amazon.

I like the lids it makes for super easy storage after playing with the watercolors.

Once the paints are dry you can create!

Get a small bowl of water. Use the paint brush and a few dabs of water to get the colors going.

We loved creating with these!

When you’re done, pop the lid back on the ice tray and put it away.

Perfect art activity for your homeschool day! How many colors can you make?

    Oh my gosh, you’re a genius! My youngest loves to paint and we go through paint sets like they are going out of style. I can only imagine the fun he’ll have if he can make his own paint, can’t wait to try this out with him.

    This is such a neat idea. I am fascinated that they make ice trays with lids (when I was growing up we didn’t have the lid kind!)
    My kids would love to do this activity. Thanks for telling this “non-crafty Momma” how to do it.

    I am so excited to try this!! I usually don’t have all of the ingredients when something is homemade, and states that most will have these ingredients around the house. But THIS time, I actually have all of the ingredients that you listed! My daughter will love this! Thank you for sharing!

    I usually have my daughter wear her special “paint shirt” over her clothes when she creates with paints, markers, etc., but just in case, do you know if these paints are washable?

    Has anyone had the opportunity to find out? How difficult was it to treat?

    Excited to try this recipe! Thanks for sharing.
