When I was in high school, I tried and tried to understand chemistry. I finally just about gave up on every truly learning about atoms and chemical bonds. I snuck through the class and wound up barely passing. Now, if I had an instructional demonstration like this, it might have ended differently.

Who would have thought that all it would have taken for me to "get it" was to have two dogs teach me all about positive and negative ions and covalent bonds and polar covalent bonds! I sure hope the chemistry teachers in our schools use these pups to help drive the point home!
