Fizzing Easter Egg Science
This activity is the classic baking soda and vinegar reaction. Because baking soda is a base and vinegar is an acid, when they mix, they cause a chemical reaction that releases CO2.
This gas bubbles up, creating the fizzing bubbles that kids love.
Aside from tasting a little gross, this science experiment is perfectly safe for little ones and is so much fun to repeat over and over!
Science is a lot of fun, and kids will love learning their first chemistry lesson in this way.
Fizzing Easter egg supply list:
Here’s what you need for this fizzing Easter egg chemistry experiment:
- Easter eggs that can stand on their own
- Baking soda
- Vinegar
- Pipettes
- Food coloring
- Play tray (we love this one!)
- Small containers
How to do the Fizzing Colors Experiment
First, put one drop of food coloring into the bottom of each egg.
Add one tablespoon of baking soda to the top of the food coloring to hide the color. Place the eggs on your tray.
Pour a small amount of vinegar for each kid into a small container. Give each kid a pipette.
Before adding the vinegar, ask the kids to guess what color the baking soda will turn.
The color surprise is another fun element of this science experiment.
Show the kids how to pick up the vinegar with their pipette and add it to the egg.
It will start to fizz and the color will be revealed!
Keep adding vinegar until it no longer causes a reaction.
If you use brighter colors, your colorful reactions will be even brighter!
Experiment with adding dish soap to see if you can get your reactions to last longer.
