Three Year Old and Chemistry Professor: a Dialog

"A DIALOGUE WITH SARAH, AGED 3: IN WHICH IT IS SHOWN THAT IF YOUR DAD IS A CHEMISTRY PROFESSOR, ASKING 'WHY' CAN BE DANGEROUS"
The Science Creative Quarterly (September 07 - April 08)

This dialog, related by Stephen McNeil, is a very believable conversation between an intelligent three-year-old, and a professor of chemistry. The subject is soap and taking a shower.

I think parents who have dealt with kids this age will particularly appreciate the professor's situation.
