Summer is almost here and if you’re looking for a fun project to keep the kids busy have you thought to make your own sidewalk chalk? This is such a fun summer project to do with the kids and it’s easy to do: choose a color, mix, pour, wait and then COLOR!
Here is what you will need:
A mold-I used my Wilton’s heart mold that we made crayons in last week. Interesting how it is much more useful now that I started using it for non-food items! There’s a huge variety of silicone molds too which would be perfect to use when you make sidewalk chalk or crayons!
Gel Food Coloring – The original tutorial I read called for Tempera powder, but I could not find it anywhere in town! So use what you have, right?
Something to mix in, something to mix with and water.

How to Make Your Own Sidewalk Chalk
First, we put a large pea-size portion of gel food coloring into a plastic cup holding 1 cup of Plaster of Paris.
We had another plastic cup with 3/4 cup of water in it. We added a little at a time and I let my little guy stir like crazy. He that it was almost magical how the little bit of color soon turned the whole concoction a bright color! We didn’t end up adding the full 3/4 cup of water. We stopped when the consistency looked like this:
We then scooped it out of the cup and pushed it down into the mold. It settled in nicely after a few seconds. Repeat the process with other colors you choose.
After about two hours, pop the sidewalk chalk out of the mold. How incredibly cute and easy is it to make your own sidewalk chalk?!
We headed outside and the kids had a blast! They were so bright and the perfect size for little hands. They wrote just like the store-purchased variety! My kids were so proud that they made it almost completely by themselves and they had so much fun creating a masterpiece to greet their Dad when he arrived home from work!
A few things:
I didn’t see the warning on the Plaster of Paris until after we had them drying in the mold. There is a warning that states: Warning: This product contains a chemical known to the State of California to cause cancer. I know that these warnings are on many things, but it’s better to be safe so I had my kids wash their hands thoroughly. Read and research these things for your own family!
Also, when you love the bright colors and go crazy with the food coloring, there are bound to be repercussions! If you don’t want tie-dye hands, you might want to use a bit less! We are still sporting purple fingertips!
Pin it for later!
My grandsons would love to make their own chalk. I love the colors!
My daughter would love to make her own chalk to write on the sidewalk and driveway with. What a great craft to do with her.
These are really cute and look like fun to make. The grandkids would love these.
This is so cool! Great for a summer time activity 🙂
I didn’t realize you can make your own sidewalk chalk! And this is easy and kid fun, too, to make. I’d love to try it!
My 2 granddaughters love to draw on our blacktop driveway with colored chalk. I never thought of making my own. This would be a fun activity to do with them. Thanks for sharing this info.
I would have never thought this was so easy and how cool to have different shape molds you could make it with.
This is a great craft!
What a cool idea!
this look fun and easy to make
