Supplies Needed

Large plastic tray – these are my favorites
Clear containers (plastic or glass)
Gel Food Coloring
Baking soda
Vinegar
Eggs
Plastic squeeze bottle

Step by Step Directions

Begin by prepping your workspace. Place all your materials and ingredients on a plastic tray or bin. Make certain to use a large plastic tray as there will be liquid overflow out of the container. This will contain any spills or messes, allowing kids to enjoy the fizzing reaction without worrying about cleanup.

To prepare the eggs for dyeing, boil them until they reach a hard-boiled consistency. Wait for the eggs to cool to room temperature before dyeing to prevent cracking during the process.

adding baking soda and gel to cup to dye Easter eggs

Prepare the dye solutions by placing 1 TBLSP of Baking soda into each cup. You’ll need one container for each color you want to use. Add a few drops of food coloring over this (5 drops).

Gently place one hard-boiled egg into each of the baking soda paste mixture, ensuring it’s fully coated.
Use a spoon or your fingers to carefully roll the egg in the mixture until it’s evenly covered with color.
Repeat this process for each color you want to use, using separate containers for each color to prevent mixing.

Thereafter, pour some vinegar into a squeeze bottle. You’ll use this to activate the color-changing reaction with the baking soda.

Pour 1/2 or 1/3 cup of vinegar into each container using a squeeze bottle, and it will bubble. (The amount of vinegar you add will depend on the size of the container). As the vinegar reacts with the baking soda, it will create a fizzing reaction and reveal the vibrant colors underneath.

Observe and experiment as the colors on the eggs change and blend together due to the reaction between the vinegar and baking soda. Submerge the eggs fully in the dye mixture for about 5 to 10 minutes.

Once you’re satisfied with the colors on the eggs, let them dry completely on paper towels or a wire rack before handling or displaying them.

You’ll have beautiful and bright-colored Easter eggs for wonderful decorations!

The Science Behind the Activity

What causes the combination of vinegar and baking soda to fizz?

It’s science! (or magic!). Basically, when the two ingredients are mixed, they release carbon dioxide which is how the fizzing occurs.

Is it harmful to mix vinegar and baking soda together?

Mixing vinegar and baking soda together is not harmful. However, if you’re concerned, ensure you supervise the kids while completing the activity.

What type of reaction is baking soda and vinegar?

When you combine baking soda with vinegar, it forms an acid-base reaction. Talk to the kids about this type of reaction and about how vinegar is acetic acid and baking soda is bicarbonate.

So many options for even more science and learning fun! This is also a great time to talk about this Baking Soda And Vinegar Reaction, too!

Tips for dyeing Easter Eggs

You can encourage creativity by mixing primary colors to create secondary colors and experimenting with different patterns and designs.

Creating patterns on Easter eggs using masking tape. Before dyeing the eggs, kids can place strips of masking tape in various patterns or shapes on the egg’s surface. After dyeing and drying, they can carefully remove the tape to reveal the white areas underneath, creating a pattern.

For the color purple, you will likely want to only use 2 drops of the gel food dye to make it a bit darker in color.

And why stop here? Hide the dyed eggs around the house or yard for an Easter egg hunt once they’re dry. This adds an exciting element of discovery to the activity.
