Eggs - Dissolving the shell

This week we are learning about the ends and outs of eggs.  To start us off, I thought we'd try dissolving the shell off an egg.

Ms. Sara's disclaimer - I've never actually done this experiment, but I've been wanting to.  So we'll see what happens!

We put raw eggs in vinegar to soak.  I've read that:  The vinegar will break down the shell (which is mostly calcium carbonate) over a few days.  Once that has occurred, we will be left with a lovely "naked" raw egg.  It will still be intact because of it's membrane.

Cool, huh!  So we'll see!

Day 1

See the air bubbles all over the shell?  That is all the air escaping from inside the shell.  Eggs have an air pocket inside that the chicken (or other critter) breaths from shortly before it hatches.
