Introducing chemical reactions need not be complex! It’s as simple as experiencing the fizzy reaction that occurs with baking soda and vinegar experiments. When my kids were toddlers and preschoolers, they LOVED exploring common household items. We would pull out medicine droppers, food coloring, water, jars in various shapes and sizes, and just play!
Frozen Baking Soda and Vinegar Fizzy Easter Eggs Science Experiments are the perfect way to celebrate Easter while integrating a fun science activity. You can dig deeper into the science of this eggs experiment, or just have fun with your kiddos getting a little messy! If they’re not quite ready for chemical reactions, there’s a whole lot to learn about freezing and melting, too!
Scientific Concepts to Learn with Fizzy Science Experiments at Home
From fine motor development to understanding chemical reactions, Easter science experiments allow you to customize the activity to suit your learners’ needs. If your child is ready to be introduced to the science behind the baking soda and vinegar reaction, here are some ideas:
- Baking soda is a basic compound called sodium bicarbonate (a form of carbon dioxide)
- Vinegar is an acetic acid
- When the vinegar meets the baking soda, the chemical reaction forms carbon dioxide gas, which bubbles
- When the ions of the two elements mix, they create two new chemicals: carbonic acid and sodium acetate
- Provide background knowledge for baking soda and vinegar science projects by pointing out the carbon dioxide bubbles found in carbonated drinks
Other concepts worth exploring include mixtures, freezing, and thawing. Ask questions to get kids thinking:
- How long do you think it will take for the eggs to freeze?
- What is happening to the baking soda/food coloring as we stir it into the water?
- Can you predict what will happen when we dip the egg in vinegar?
- How can you get the frozen egg to thaw slower/faster?
How to Make Frozen Fizzing Easter Eggs
- ¾ cup baking soda
- ¼ cup warm water
- Food coloring
- Egg-shaped silicone mold
- Shallow bowl

1. In a large mixing cup, stir together the baking soda and water until the baking soda dissolves.
2. Add a few drops of food coloring.
3. Pour the mixture into the egg-shaped silicone mold and freeze overnight or until completely frozen.
4. Pour vinegar into a shallow bowl.
5. Carefully lower the frozen egg into the vinegar or use a dropper to add vinegar to the frozen egg.
How to adapt the baking soda and vinegar science experiment:
- Reverse the process by creating the eggs using a solution of vinegar and water. Freeze, then dip the frozen eggs into a solution of baking soda and water.
- Experiment with different ratios of baking soda to water when freezing the eggs to see which brings a more exciting reaction.
- Incorporate an egg drop or an egg toss before dissolving the eggs.

Fizzy eggs or other Easter baking soda science activities require basic ingredients from the pantry just waiting to be used up! Grab your vinegar, baking soda, food coloring, and whatever else you might find, and get creative! Don’t forget the paper towel!
- Place jelly beans (or other Easter candy) in containers of different liquids (water, vinegar, juice, pop, etc.) to see what happens.
- Grow crystals with borax on pipe cleaners shaped like eggs or bunny heads, or grow them inside of egg shells.
- Place boiled eggs in vinegar for a bouncy result.
- A fun baking soda and vinegar experiment for kids is to propel those plastic eggs with rockets propelled by the chemical reaction.
