Rubber Egg Science Experiment for Classic Kid's STEM!

This rubber egg science activity is a classic! Make a naked egg or bouncing egg. Can it bounce? What happens to the shell? Does light pass through it? So many questions and one simple experiment using everyday supplies. We think science should be exciting, easy, and fun! All our simple science experiments are perfect for early learning.

There are so many interesting science activities with real eggs! This classic rubber egg science experiment is very cool and easy to set up. The only difficult part is the waiting! A whole week in fact is what you need to wait.

After you set up your rubber egg experiment, why not try a simple egg drop engineering activity, see if you can make an egg float, or test the strength of the shell! Can you make a crystal egg shell?

SUPPLIES

Eggs

Vinegar

Jar/Vase

I knew this egg experiment existed and it is a classic science experiment. I checked in with Steve Spangler Science to see how to make our naked egg and understand the science behind it!

You can read all about the chemical reaction between the vinegar and the egg shell and osmosis with Steve Spangler!

MAKE A RUBBER EGG

Place egg in jar and cover with vinegar. 24 hours later, drain and refill with vinegar. Set aside and patiently wait 7 days. Yes! One whole week until your naked egg is ready. After 7 days, remove egg and rinse off. Ours had a layer of brown scum that was easily washed away!

Now for the fun part, exploring the naked egg with your child! We gathered a few supplies such as a magnifying glass and a large flashlight. However, first we talked about what our naked egg felt and looked like. We had made a cool runner egg!

Help your child learn to explore by asking questions to spark curiosity!

What does the egg feel like? What color is it? Is it hard? Is it squishy. All of these questions encourage exploration and hands-on learning. Have him use his senses to observe. What does it smell like? What does it look like? There are so many ways to explore. Grab the magnifying glass too!

Does the naked egg bounce? Why, yes it does!

What happens when you put the egg up to a flash light? You can see through it! You can see the yolk rolling around inside.

Of course, we were prompted to wonder what would happen if your burst the naked egg. WOW! With a quick prick from a skewer, the egg burst! We were all quite surprised. The images below show what the naked egg looked like afterward.
