We're Magicians: First You See an Eggshell...Now You Don't!
After sitting for the rest of the day and all night, my students were anxious to see what changes had taken place. They put their Scientist's Goggles on (so to speak) and observed the egg. We noticed that there was a lot of things floating towards the top of the bowl of vinegar. We decided to explore further and touch it. When I rubbed it with my thumb, the shell (or what used to be the shell) came right off! The kids oohhhed and awwweed; they were pretty impressed. After the entire white shell was off, we were left with an egg whose yolk you could actually see. I had my students come up and hold it in their hands to feel our egg's newfound texture: we decided the best way to describe it was "water balloon."
We are now exploring another experiment with this egg. We poured Karo Syrup over the top of the egg and are interested to see what results we get with this one! Stay tuned!
