Materials Needed to Make DIY Fizzy Sidewalk Chalk Paint

  • Baking soda
  • Cornstarch
  • Water
  • Liquid food coloring
  • Vinegar
  • Mixing bowls
  • Whisk or spoon
  • Ice cube trays or silicone molds
  • Plastic wrap or aluminum foil
  • Spray bottles (optional)
  • Paintbrushes (optional)

How to Make DIY Fizzy Sidewalk Chalk Paint

Step 1: Mixing the Base

In a mixing bowl, combine equal parts baking soda and cornstarch. For a small batch, start with 1/4 cup of each. Mix them together thoroughly, ensuring there are no lumps. The baking soda helps create the fizzing effect, while the cornstarch provides the chalky consistency.

Step 2: Adding Color

Divide the base mixture into separate bowls or an old muffin tin, depending on how many colors you want to create. Add a few drops of liquid food coloring to each bowl and mix well. Feel free to experiment with different hues by combining various colors.

Step 3: Adding Water

Gradually add water to each bowl, a tablespoon at a time, while stirring. The goal is to create a thick, paste-like consistency that is easy to pour into molds. Be careful not to add too much water, as it may make the chalk mixture too thin.

Step 4: Artistic Exploration

Now comes the most exciting part! Take the DIY fizzy sidewalk chalk paint outside and let the kids’ imaginations run wild. The chalk paint can be used like traditional sidewalk chalk, but with an extra twist. When sprayed with vinegar, it creates a fascinating fizzing reaction that adds an extra element of surprise and excitement.

NOTE: This paint is made using food colouring so test the paint on a sidewalk or walkway in a corner before using to ensure that it doesn’t not stain.

Step 5: Spray Bottles and Paintbrushes

For a more interactive experience, fill spray bottles with vinegar and let the kids spray the chalk drawing. This hands-on approach enhances the fizzy reaction and allows for experimentation with different spraying techniques. Additionally, providing paintbrushes allows children to dip them in vinegar and paint directly onto the chalk drawings, producing captivating effervescent effects.

With this easy and engaging DIY fizzy sidewalk chalk paint recipe, you can create a memorable outdoor activity for kids. Not only will they enjoy the vibrant colors and unique texture of the chalk, but they’ll also be captivated by the fizzy chemical reaction it produces. So, gather the materials, let your little ones unleash their creativity, and watch as their imaginations take flight with sparkling sidewalk art!

Clean Up

To prevent any possible staining remove the paint from the your stone walkway or sidewalk using a hose immediately after painting.

The Science Behind Baking Soda and Vinegar Experiments

Acid-Base Reaction:
Baking soda (sodium bicarbonate) is a base, while vinegar (acetic acid) is an acid. When they combine, the acid-base reaction takes place, resulting in the formation of carbon dioxide gas, water, and a salt. The release of carbon dioxide gas causes the fizzing and bubbling effect we observe during the experiment. This reaction provides an excellent opportunity for children to explore chemical reactions and understand the fundamentals of acids and bases.

Age Suitability
