Arawan,

I didn't know the story as a child, myself, I only discovered it once I had children of my own. But, that doesn't mean that I don't love it. I have also used it with my students to get the point that sometimes observations first observations don't give you the whole picture.

Johnny was a chemist,
Now Johnny is no more,
For what he thought was H two O
Was really H two S O four.
