How To Dye Marshmallows

Don’t have colored marshmallows at home? No problem. You can use food coloring to make color marshmallows. Just make sure you give them enough time to dry before gluing them to your final craft.

If you only have small white marshmallows, you will want to dye them with food coloring.

Step 1: Make Baggies For Different Colors

Place the number of marshmallows you think you will need for each color in a plastic bag. Add only a few drops of food coloring and about a tablespoon of water. 

Step 2: Add Food Coloring

Zip the bag closed and move the marshmallows around. My toddlers loved seeing the marshmallows change colors.

Step 3: Let Marshmallows Dry

Once you have made your colored marshmallows, empty the bag on paper towels. Leave the marshmallows there to dry to at least 30 minutes. I recommend having several layers of paper towels on your counter.

Marshmallow Dying Tip

You can use fewer bags if you make the colors in the order of the rainbow. Start with red, dump out red marshmallows. Then place new white marshmallows in the bag and just add two drops of yellow.

Repeat for all the colors of the rainbow going in ROYGBIV order!

Your children not only have fun seeing the marshmallows change colors, but they also will learn about color mixing. If want to make this even more educational, you could read one of my favorite color mixing books as well!

Or you could also what my favorite color mixing video! Preschoolers and young children absolutely love this video!

How To Make A Textured Rainbow Craft

Step 1: Cut Arc Out

As marshmallows are drying, cut a rainbow arc shape out of cardboard. I took apart a cracker box. The back of the rainbow is the outside part box.

Step 2: Sort By Colors

Once marshmallows are dry enough, have children sort them by colors. Sorting is a great activity in itself for preschoolers!

Step 3: Draw Rainbow Design

Draw rainbow lines and clouds if you want. Decide how many colors will be in your rainbow. Draw that many arced lines.

Step 4: Use Glue

Since my kids are preschool-aged, I decided to put the glue down for them. This also helped because I worked in sections.

Step 5: Continue Adding Marshmallow

Only put glue down for one color at a time. My daughter was so proud when she would finish one of the colors.

If you have elementary-aged children, then they should be able to do everything for their rainbow craft themselves (from drawing the rainbow to gluing).

My preschoolers were so proud of what they created. The only thing is that you have to encourage your children to not eat marshmallows if they have glue on their fingers…

Oh the joys of being a preschooler! Don’t eat the glue!

I promised a small bowl of fruity marshmallows once they finished their rainbow art project.
