Rainbow Crayons

How many old crayons do you have around the house? Do you ever worry that they are feeling sad and ignored? You can give them new life with this project. They will no longer be old and unwanted. They will magically turn into an awesome gift. This is a fun art project that recycles old crayons and turns them into awesome party favors!

DYI Rainbow Crayons



Old Crayons

Muffin tin or Silicon mold



Gather up all of your broken crayons, and cut them into small pieces. (An adult will need to complete this step. Or you can try to break them with your fingers for a sensory activity.

Preheat the oven to 250 degrees.

Fill the muffin tin with an inch-thick layer of crayon pieces.

Bake 15-20 minutes, or until the wax is melted.

Allow the tin to cool; then pop out the crayons, and they’re ready for use.


  1. If you don’t have a muffin tin to devote to crayon making, you can line your regular muffin tin with foil cups.
  2. Candy and soap making molds can also be used to create fun, shaped crayons.
  3. Recycled crayons make a great no-cost gift or party favor

Now if you want to have even more fun and extend this activity you can make your own solar oven and use that to make your Rainbow Crayons!
