A DIALOGUE WITH SARAH, AGED 3: IN WHICH IT IS SHOWN THAT IF YOUR DAD IS A CHEMISTRY PROFESSOR, ASKING “WHY” CAN BE DANGEROUS SARAH: Daddy, were you in the shower? DAD: Yes, I was in the shower. SARAH: Why? DAD: I was dirty. DAD: Why does the shower get me clean? SARAH: Yes. DAD: Because the water washes the dirt away when I use soap. DAD: Why do I use soap? DAD: Because the soap grabs the dirt and lets the water wash it off. DAD: Why does the soap grab the dirt? DAD: Because soap is a surfactant. DAD: Why is soap a surfactant? DAD: That is an EXCELLENT question. DAD: Why does soap form micelles? DAD: Soap molecules are long chains with a polar, hydrophilic head and a non-polar, hydrophobic tail. SARAH: Aidrofawwic DAD: And can you say ‘hydrophobic’? DAD: Excellent! DAD: Why does it mean that? DAD: It’s Greek! SARAH: Like a monster? DAD: You mean, like being afraid of a monster? DAD: A scary monster, sure. (pause) SARAH: (rolls her eyes) I thought we were talking about soap. DAD: We are talking about soap. (longish pause) DAD: Why do the molecules have a hydrophilic head and a hydrophobic tail? DAD: That’s complicated.
