Stephen McNeil is a chemistry professor, a dad, and a smartass. Or at least a Canadian. It took me a couple of days of reloading, but I finally got to read his miraculous story of reaching the end of his 3-year-old daughter's tireless string of Whys.
Though I still want to know what a micelle is. And it's important not to pass up the chance to teach a kid how to pronounce and use an obscure technical term like "hydrophilic" and "hydrophobic." [In our house, "homonym" is a classic.] Guaranteed to entertain and intimidate your family and friends for years to come.
Really enjoyed that dialogue!
(Although it makes me realise that our kid is doomed. Both parents are PhDs. And Canadian. I see lots of lectures and long-winded answers in his future...)
