Crafting with Kids: Melted Crayon Rocks

Crafting with Kids

Our “Dig Into Reading” theme for the Summer Library Program (SLP) has been lots of fun.  From digging for dinosaur bones to exploring the dirt underneath our feet, there are many ways for children to investigate the natural world around them.  Many branches offered a program that let the participants touch and feel different kinds of rocks, including some gems and minerals.  After the program, the children got to make their own awesomely decorated rock with a few simple materials.

So this month, our featured craft will be Melted Crayon Rocks.  Keep reading to find out how to make them!

Materials:

  • Old crayons
  • Zip-to-close plastic bag
  • Wooden or rubber mallet
  • Smooth, flat rocks about the size of your fist
  • Aluminum foil or an old pie tin
  • Felt scraps
  • Scissors
  • White glue

Instructions:

IN THE SUN METHOD

  1. Choose crayons in three or four light or bright colors.  Dark crayons will make the color on the rock look muddy.
  2. Peel the crayons, put them in the zip-to-close bag, and seal it.
  3. Place the bag on a hard surface such as a floor or sidewalk.  Using the mallet, pound the crayons into small pieces.
  4. Place the rock in the pie tin or on a sheet of aluminum foil in the hot sun.  Sprinkle it with the crayon pieces.

When the crayon pieces have melted, but before they reach the point that they run off the rock, take the rock out of the sun to cool.  The crayon will quickly harden and form a colorful and waxy coat over the rock.  Cut a piece of felt to glue to the bottom of the rock to keep it from scratching the table.

TIPS: IF WEATHER ISN’T HOT

  1. Preheat the oven to 350 degrees.  Place the rocks on a foil covered cookie sheet and put them in the oven for the children.  Keep an eye on them because the crayon melts quickly. It will re-harden within seconds of taking it out of the oven.
  2. To do outside — this project needs hot, direct sunlight.
  3. If you’re unhappy with the color of a crayon-coated rock, just reheat the rock and allow the crayon to melt to the point where most of it drips off the rock and onto the foil under it.  Cover the rock with a new selection of crayon bits and see if you get a swirl of color you like better.  Remember to avoid dark colors.
  4. A goal is to get it looking like a tie-dyed rock!  The distinct lines of color can be very beautiful.  Because the rocks can be easily redone, remember not to place the completed ones that you like in a sunny window or direct, hot sunlight because they will re-melt.

Thanks to Miss Heather at Butler and Lucas for the detailed instructions!  This rock craft is something that anyone can do with minimal supplies and time (’cause nearly everyone has rocks and old crayons lying around, right?).
