Squishy egg

This is a fun, super easy experiment we did last week. (I found it on the Clorox website.)  We used vinegar to dissolve the shell on an egg, which left us with a squishy, naked egg! It was really neat. (Here's a website that explains the reactions and why it happens.)

You'll need:

an egg

vinegar

a container deep enough to cover the egg with vinegar

2 days

First, place the egg in a container, and pour vinegar in until the egg is completely covered. This is what the egg looked like right after we poured the vinegar into the glass -- the bubbles started forming immediately.

 Put the container in the refrigerator, and leave it there for 2 days. Change the vinegar after 1 day. 


This is what the egg looked like after about 36 hours:  

 This is what the egg looked like after 48 hours:

It was really cool! The shell had dissolved completely. The egg really was squishy, and the kids were able to hold it and bounce it (very gently!) on the countertop. 

Then the 3 year old squeezed it a little too hard and that was the end of the egg. :-)  But it was super fun and really interesting!
