Have lots of crayon stubs that are too small to hold on to? Don't throw them out! You can use them to create big, chunky crayons – and your kids can help.

Difficulty: Easy

Time Required: 25 minutes

What You Need:

  • Broken crayons
  • An old muffin tin
  • A knife

Here's How:

  1. Gather up all of your broken crayons; unwrap them; and cut them into small pieces. (An adult will need to do the cutting)
  2. Preheat your oven to 250 degrees.
  1. Fill the cups of your muffin tin with an inch-thick layer of crayon pieces. Do one color in each cup, or mix all the colors together to create rainbow crayons.
  2. Bake 15-20 minutes, or until the wax has melted. Stay close by to keep an eye on things.
  3. Allow the crayons to cool and harden; then pop them out, and they're ready to 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. The wax may stick to paper cups.
  2. Candy and soap making molds can also be used to create fun, shaped crayons. Just make sure they're oven-safe. I like to work with silicone molds because it's really easy to pop the crayons out when they're done, and because there are so many great shapes to choose from.
  3. It's probably no surprise, but name brand crayons make the best recycled crayons. All of the color tends to settle on one side of the crayon when you use the cheapies.
  1. Recycled crayons make a great no-cost gift or party favor. Give them for Valentine's Day or hand them out on Halloween as a fun alternative to candy.

Still have a bunch of broken crayons left over after making crayons? Use them to make candles and fire starters. As long as you supervise, your kids can help with these, too.

 Here are some fun projects to try. 

If it's a sunny day, try making a solar crayon candle. Just place a wick in the center of an old jar; fill it to the top with broken crayon pieces, and sit it outside on a piece of aluminum foil. As the sun melts the crayons, add more, until you have enough melted crayons to fill the entire jar. Measure the diameter of your jar to figure out what size wick you need. If you get the wrong size it won't burn properly.
