semperfionaTwo weeks ago Tuesday, Tammie had a job interview for a lab position at WashU. (She called a few minutes ago to announce that SHE GOT THE JOB!!! ***SQUEE***) When she got home, Rosa put her little hands on her hips, confronted Tammie, and demanded, "Why didn't you pick me up?"
"Because Chris picked you up today."
"But you always pick me up!"
"I had a job interview."
"What kind of job?"
"A science job."
"SCIENCE!!!! I LOVE SCIENCE!" Rosa ran upstairs and grabbed the little Kitchen Chemistry kit she got for Christmas. "Let's do some science!"
Tammie begged off for the time and when I got home from work I was enlisted. I read through the book looking for something that didn't take much prep or make much mess, and picked "Rubbery Recipes". We found two small jars, put one of Roger's fresh brown eggs (harvested by Rosa herself, like as not) in one and a chicken bone from the previous night's fried chicken in the other, and filled them each with vinegar.
Sunday, we opened the egg jar. Sure enough, the shell was rubbery. Poking it gently it bounced back. Very similar to the texture of a peeled hardboiled egg, actually. Also, little brown granules rubbed off of it at a touch.
Not only that, but the egg had expanded. While it went *into* the jar easily enough, it did not want to come *out* again. Thinking I would push it back out of the neck of the jar, I poked it again. It POPPED.
Ew. Egg goo in vinegar with rubbery popped-balloon-like shell fragments, and a nasty smell. Closed the jar back up and put it in the trash.
The chicken bone is still stewing. Updates to come.

Our next project is a cabbage juice acid/base indicator. :-)
