This simple project, adapted from "Summer Crafts" by Marjorie Galen (Hylas, 2005), transforms rocks into giant waxy jewels. The secret ingredients? Crayons and heat!
What you'll need
- Smooth, flat rocks
- Aluminum foil
- Oven mitt
- Newspapers
- Old crayons
How to make it
- After you've gathered some smooth, flat rocks, clean them off, and bake them for 15 minutes on a foil-lined cookie sheet in a 225ยบ oven.
- Using an oven mitt, remove the rocks from the stove and set them on a pad of newspapers (note: the rocks will be very hot to the touch).
- Remove the wrappers from some old crayons and draw on the stones -- the heat will melt the crayons into vibrant liquid wax. For the swirly effect shown here, hold each crayon against the rock in one place to create a puddle of color and use the end of the crayon to swirl it around.
