4 Egg Experiments You Have to Try
With spring in full swing and Easter right around the corner, 4 egg experiments you have to try are a perfect way to add hands-on science to your week. We had done a few of these before, while others were new to us, so it was a fun mix of familiar favorites and fresh ideas.
For more low-prep ideas, check out my list of Simple Homeschool Science Experiments.
My kids love any science experiment that involves a mess, or even the possibility of one. They love to be fully hands-on and watch the cause-and-effect of their favorite experiments, even the ones they have done over and over.
Grab a couple of dozen eggs, choose the activities that fit your day, or try them all with your kids.

Why Egg Experiments Are Excellent for Hands-On Learning
Egg science experiments make homeschool science easy to see and understand. When my older kids were younger, I liked using kitchen science because it kept lessons simple, hands-on, and memorable.
- Easy setup: Most supplies are already in your kitchen.
- Real science: Kids can learn about air pressure, density, gravity, force, and motion.
- Hands-on fun: Eggs keep kids curious because the results are easy to watch.
- Flexible for ages: Younger kids can observe while older students record and explain results.
Recommended Science Experiment Books
Science experiment books are helpful when you want easy homeschool science ideas, without having to plan everything from scratch. I liked having simple activities on hand when my kids needed a hands-on lesson that used supplies we already had.

What Topics Can You Discuss That Are Related to Eggs?
Egg activities can lead to quick but helpful science talks. You can keep the lesson simple or stretch it into a deeper discussion.
- Density and buoyancy: Compare why eggs sink in water but float in salt water.
- Air pressure: Use the egg vacuum experiment to show how pressure can move an object.
- Force and gravity: The egg drop helps kids test how padding protects a falling egg.
- Shell strength: Walking on eggs shows how shape and pressure affect strength.
What Skills Will Kids Learn From These Egg Activities?
Egg experiments help kids practice science skills without a complicated setup. I liked that my older kids could make guesses, test ideas, and talk through what happened.
- Observation: Kids notice changes, reactions, and movement.
- Prediction: They guess what may happen before testing.
- Problem-solving: The egg drop encourages kids to adjust their design.
- Fine motor skills: Measuring, pouring, and placing eggs carefully build control.
- Science vocabulary: Words like density, gravity, pressure, and buoyancy become easier to understand.
- Communication: Kids explain what worked, what changed, and why.

4 Egg Experiments You Have to Try
Before doing each experiment, have your children hypothesize what the outcome of each one will be. Older children can write out their hypothesis and their findings.
Sink or Float Egg Experiment
This experiment is a great test of the buoyancy of fresh and saltwater.
Supplies needed for this sink or float experiment
- 2 clear glass jars or bowls
- 2 eggs
- table salt
- measuring cup
- spoon
How to do the experiment
- Fill your two glass jars ¾ of the way with very warm water.
- Make sure they are wider and taller than your eggs.
- Stir ¼ cup of salt into one jar until it is dissolved.
- Gently place an egg in each jar.
- Observe what will happen.
How does it work?
The salt makes the water denser, allowing objects in it to float to the surface.
Ways to extend the activity
Try experimenting with different amounts of salt in the water and let your child discover what happens.

The Egg Drop
The egg drop activity is a classic hands-on science experiment that lets kids design, test, and improve their ideas. I liked doing this with my older kids because it turned into a fun challenge that made them think carefully about how to protect the egg before letting it fall.
Supplies needed for this egg drop experiment
- a glass of water ¾ of the way full
- a pie tin
- an empty paper roll
- an egg
- some towels (in case you need to practice a few times to get it right
How to do the experiment
- Center the pie tin on top of the glass of water
- Center your paper roll on the pie tin
- Carefully place the egg on top of the roll
- Try to get the egg into the glass of water by only touching the pie tin.
You can whack it quickly with your hand, or you can do as we did- set the jar close to the edge of the table so that the pie tin is even with the edge of the table, step on the bristles of a broom and pull the handle back, let it snap towards the pan.
Hopefully, what has happened is that the pan and paper roll fly out, and the egg drops inside the water.
How does it work?
How does it work? Newton’s first law of motion comes into play here, and an object at rest stays at rest (the cup and egg), and an object in motion stays in motion (the roll and pie tin). The egg stays in place, but with nothing to support it, drops straight down.
Ways to extend the activity
Try experimenting with different amounts of salt in the water and let your child discover what happens.
Egg Vacuum Experiment
Kids will be amazed as the egg is sucked into a bottle whose opening is obviously smaller than the egg itself. How in the world does this happen?
Supplies needed for this sink or float experiment
- a hard-boiled egg
- a glass bottle with an opening that is smaller than the widest part of your egg
- a match/lighter
- scrap paper
How to do the experiment
- Cut a strip of paper about 6” long and 2” wide
- Twist it firmly, light it, and drop it into the jar
- Set the egg on top, wider side down
- Once the paper burns itself out, the egg will be drawn slowly into the bottle until it hits the bottom!
How does it work?
The air, heated by the fire, expands. As the air begins to cool, the molecules shrink up and create a vacuum. The air on the outside tries to press into the bottle and suck the egg into the vacuum.
Ways to extend the activity
Try using bottles with slightly different openings and ask your child to predict which one will work best. You can also have them draw a quick before-and-after diagram to show how the egg moved.
Walking on Eggs
Walking on eggshells is no fun unless it’s a hands-on (err, feet on) experiment where your little ones get to be involved.
Supplies needed for this sink or float experiment
- 2 dozen eggs
- Plastic dropcloth, just in case.
How to do the experiment
- Try a couple of things with your eggs first: break them on the side of a bowl and encourage your child to squeeze the egg in their hand. What happens? Why does the egg break when hit on the bowl but not in a hand?
- Now have your child get on the eggs with your help and try to walk over them, applying even pressure with their feet. If they dig in with toes or heels in spots, however, they may break the eggs.s
How it works
The simple answer is that when squeezed in your hand, even pressure is applied to the curved surface of the egg, and it distributes the force evenly.
Cracking it on a hard bowl or pan, on the other hand, concentrates all the force in a small area, and the egg breaks. The same principle applies to walking on eggs; when even pressure is applied over the entire surface of the eggs, they will not break.
Ways to extend the activity
Let your child compare standing on one egg carton, two cartons, or a wider egg setup to see how support changes.
Other Egg Experiments Worth Trying
You can keep the science going with more kitchen science activities and easy hands-on projects. These work well when your kids want another simple experiment after trying egg science.
- Try edible kitchen science: Use these experiments for more food-based ideas.
- Make chia seed dinosaur eggs: Try How to Make Chia Seed Dinosaur Eggs for a sensory science activity.
- Test a rubber egg: The Rubber Egg Experiment is a great follow-up to the vinegar-and-egg experiment.
Use egg experiments to make science hands-on without a long supply list. Your kids can test density, air pressure, gravity, and shell strength while making predictions and seeing the results right away.
