My three year old and I have been having lots of fun making different shapes of crayons. We started by making pumpkin shaped crayons. Then, we made seashell shaped crayons for her under the sea birthday party. Using silicone molds to make them was lots of fun, but I wanted a way to make them without needing to buy a mold. I read about making crayons in straws, but my daughter’s pouring skills aren’t quite ready for hot crayon wax. So, I thought through what I can use in the oven and aluminum foil came to mind. I knew I couldn’t make any intricate designs with it, but it gave me the idea for these rock crayons.

How to Make Rock Crayons:

Materials:

Creating:

First, tear off as many squares of aluminum foil as you want crayons. My daughter and I only made two crayons, so we used two pieces of aluminum foil.

Then, you need to prep your crayons by taking all the wrappers off. I already had a bunch of old beat up crayons that I had taken the wrappers off of for previous crayon crafts. Kids can definitely help with this step.

Once your crayons are ready, your child can pick which ones they want for each new crayon. They need broken up a little bit before your child places them on the aluminum foil. My daughter was able to break the really long ones in half, but I helped her with some of the others.

When you have plenty of crayon pieces on each piece of aluminum foil, it is time to wrap them up. My daughter very enthusiastically did this step. I undid a bit of her work to leave a hole at the top to help the crayons melt better. If you accidently tear a hole in your foil, get a new piece and try again. If the crayon leaks out while baking, they will not work. Then, put your balls of aluminum foil on top of an aluminum foil lined cookie sheet.

Next, you need to preheat your oven to 350 degrees Fahrenheit. This is a lot hotter than I used for my previous crayon crafts, since the aluminum foil insulates the crayons. Then, place your crayons in the oven while your child watches from a safe distance. Be careful not to drop any. Unfortunately I know from experience how hard crayon is to clean out of an oven. Bake your crayons for about 15 minutes or until all the crayons look melted.

After you take your crayons out of the oven, it will take a while for them to harden up. It is important to give them lots of time to cool down. Once your new crayons are hard, you can unwrap the aluminum foil. Now, you have super fun rock crayons!

Conclusion of Making Rock Crayons:

These rock crayons were so simple to make and I love how they only required aluminum foil and old beat up crayons. My daughter thought her new crayons were fun to color with. She even shared them with her one year old brother. He enjoyed them since they were bigger and easier for him to hold. If you are looking for a good way to reuse old crayons without having to spend money on a silicone mold, I would definitely recommend trying these.
