Easy Rainbow Craft For Toddlers & Preschoolers
Learn how to create a fun rainbow craft using marshmallows. Our children had so much fun using supplies we already had at home.

If you are like my family, you are looking for anything to entertain your children. This easy marshmallow craft is so much fun. And it didn’t hurt that they got to eat some marshmallows in the process!
MOM TIP– Let the kids eat some marshmallows before the glue comes out. Or don’t glue the marshmallows if you are only looking for a temporary marshmallow craft.

How To Dye Marshmallows With Food Coloring
Don’t have colored marshmallows at home? No problem. You can use food coloring to make colored marshmallows. Just give them enough time to dry before gluing them to your final craft.
Step 1: Make Baggies For Different Colors
Place the number of marshmallows you need for each color in a plastic bag. Add only a few drops of food coloring and 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 into paper towels and leave the marshmallows there to dry for at least 30 minutes. I recommend having several layers of paper towels on your counter.
Marshmallow Dying Tip
If you arrange the colors in the order of the rainbow, you can use fewer bags. Start with red marshmallows and dump them out. Then, place new white marshmallows in the bag and add two drops of yellow.
Repeat for all the colors of the rainbow going in ROYGBIV order!
Your children will not only have fun seeing the marshmallows change colors but also learn about color mixing. To make this even more educational, you could read one of my favorite color-mixing books!
Or you could also what my favorite color mixing video! Preschoolers and young children love this video!

Marshmallow Craft Tutorial
Step 1: Cut The 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 of the 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 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 finished one of the colors.
If you have elementary-aged children, 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 not to 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.
