This is a very fun and explosive way to dye Easter eggs! It can be done as a science experiment with students or as an exciting egg decorating activity.
You will need:
a container for each color
hard boiled eggs
Cover the bottom of a container with baking soda.
Add a packet of Kool-Aid to the baking soda and mix well. You can also use powder tempera paint in place of the Kool-Aid however the paint makes the eggs toxic and they should NOT be eaten. I prefer to use the Kool-Aid instead because it is safer and it colored the eggs just as well.
Place an egg in the center of the baking soda and Kool-Aid mixture.
I did this as a science experiment and before adding the vinegar I had students predict what they thought would happen and record their answers.
Pour vinegar over the mixture and watch what happens!
The vinegar (acid) reacts with the baking soda (base) causing it to “explode” or “erupt” and foam up over the egg. Students and children LOVE it (and I do too LOL)! When the foam goes down a colored egg is revealed.
After the experiment was over I had students record the actual results.
