Inspired by that I set up this rainbow egg experiment. The results were AMAZING! Here, you will see what we did, what questions were posed, and the outcome of our experiment.
RAINBOW EGG EXPERIMENT FOR KIDS
Materials needed for this experiment: (affiliate links provided)
- Glass jars
- Food coloring
- Vinegar
- Raw eggs
Before beginning the experiment
Before beginning our experiment I asked Rosie and Jewel what they thought would happen if we placed uncooked eggs in colored vinegar. I reminded them of the results from our previous experiment. I asked them questions like:
- Do you think the colored vinegar will remove the shells from the eggs?
- Do you think the colored vinegar will color the eggs?
- Do you think you will be able to see through the eggs if the shells are removed and the eggs are colored?
After they made their hypotheses we began the experiment.
Setting up the experiment:
You will need seven jars if you wish to have one for every color of the rainbow like we did. Fill each jar with enough vinegar to fully submerge one egg. Add several drops of food coloring to each jar and stir well
To get every color of the rainbow you will want to use neon food coloring in addition to the standard colors. Once the food coloring is mixed into the vinegar carefully place one uncooked egg into each jar
That's it! Set up for this experiment is really easy!
The experiment:
- Will the eggs change color in the vinegar?
- Will the vinegar eat the shells from the eggs like it did in our previous experiment?
- If it does will the eggs be colored all the way through, just on the surface, or not at all?
Observe the jars over the next couple of days. Visit the jars often & make note of any visible changes. After 2-3 days the eggs can be removed from the jars and further observations can be made.
What happened?
- After 3 days we removed our eggs from the jars. This is what we saw
The eggs had changed color and had no shells
All seven eggs were completely shell-less & vibrantly colored by the vinegar solution
And when held under a light source we discovered that the eggs were transparent!
How cool! This experiment was so fun with a tiny bit of magical appeal thrown in! The photos do not do it justice. You will have to try this in order to see just how cool these eggs looked when held under a light. I know this is one experiment we will be revisiting again really soon!
The science behind the experiment:
Why does the vinegar eat the shells from the egg? How does the egg stay formed "inside" if there is no shell? This and the answers to many other questions regarding this experiment can be answered here. Steve Spangler Science explains it all & more.
