Here are some pics from our latest science experiments. 

The Naked Egg

We just completed this one today. One week ago we placed an egg into a jar of vinegar. What you get out is a naked egg. What happened? The eggshell is a base, calcium carbonate, and the vinegar is an acid. The acid slowly eats away at the shell, while the membrane of the egg stays intact. It was really cool, but stinky.

Check out the video link to watch how it works.

Seven Layer Density Tower

This one was an experiment on density. We took seven different liquids 

and layered them according to their density level. 

It was really neat, even if you stirred it all up it would go in order.
