After finding a rock, clean it off with soap and water. Then stick it into the oven (we used our toaster oven) for a few minutes. I set my toaster to about 350 degrees. The rock was hot to touch (I used a dish towel to transport mine) so this is definitely a project that requires close supervision.
Place your rock on some newspaper and if you have a specific hue you’re going for, place a set of those specific crayons for your child to use. Since our rock was heart shaped, I chose pinks and reds.
Use the crayons directly on your rock and be amazed at how vibrant the color comes out! After covering your rock, set it aside to dry.
I wanted to jazz up my rock (my soon-to-be-paperweight) so I added white dots with nail polish. After that dried, I added a clear coat of nail polish to seal the color in.
