Baking soda and vinegar reaction is our #1 simple science experiment, and it is versatile for each holiday! Of course, Easter has to have a baking soda and vinegar reaction, like these fizzy rainbow Easter eggs! Open the kitchen cupboard and start immediately on this baking soda and vinegar rainbow Easter Eggs activity.
Fizzy Rainbow Easter Eggs
Let’s explore this chemical reaction with baking soda and vinegar. Head to the kitchen, open the pantry, and be prepared to get messy. Make sure to have a tray and paper towels available for spills!
💡 This RAINBOW EASTER EGGS activity asks the question: What happens when you mix baking soda and vinegar? Check out all of our Easter Science Activities here.
Supplies:
- Plastic eggs
- Egg tray
- Eyedropper, squeeze bottle, or meat baster
- Baking soda
- Vinegar
- Food coloring
Vinegar and Baking Soda Easter Eggs
💡 Did you know you can dye your real Easter eggs with baking soda and vinegar?
STEP 1: Set up a tray with an egg carton (clear plastic or styrofoam will work best) and set up your eggs.
STEP 2: Add several drops of food coloring to each egg (this step is optional but very fun for surprise color eruptions). You can also color separate containers of vinegar and let the kids mix and match colors.
STEP 3: Now, go ahead and fill each egg with a spoonful of baking soda! You can add a pinch of glitter on top if desired!
STEP 4: Now it’s time for the excitement! Set out a bowl of vinegar for eyedroppers or meat basters. Or you can fill a squeeze bottle with vinegar.
Tips For Baking Soda and Vinegar In The Classroom
Kids will love testing and retesting this simple chemical reaction, so I always recommend having extra vinegar on hand. If you are working with a group of kids, use small bowls and one egg each!
Don’t like the smell of vinegar? Try this activity with lemon juice and baking soda instead! Since lemon juice is also an acid, it produces a chemical reaction when combined with baking soda. Check out our lemon volcanos!
The plastic eggs will get messy, but you can turn the end of the activity into an egg washing station and water sensory bin too!
The Science of Baking Soda and Vinegar
The science behind these fizzy rainbow Easter eggs is all about the baking soda and vinegar and the fizzy bubbles that result!
When the acid (vinegar) and the base (baking soda) mix together, a chemical reaction happens. The baking soda and vinegar get used up in making a new substance, a gas called carbon dioxide. The fizzing bubbling action you can see and even feel if you put your hand close enough, is the gas!
All three states of matter are present: liquid (vinegar), solid (baking soda), and gas (carbon dioxide).

I follow you daily/weekly for the letter of the week that I do with my Pre preschool kids. I haven’t started them in a real preschool program as of yet as they are just 3 but wanted them to be ready for the preschool in the fall. Its been sooo much fun following your activities!! you make my work so much easier. We will do this activity this week and follow by egg washing. Thank you.
My son adores activities like these! Thanks for allowing me to share in my Easter Roundup 🙂
