This is why I am in awe of Older Daughter. It’s an experiment she set up for our almost-5-year-old grandson, also known as Capt. Adorable, sort of along the lines of a “Sid the Science Kid” investigation. (Speaking of Sid and his preschool co-horts, am I the only person who thinks Gerald will turn out to be Keith Moon‘s grandson?) Older Daughter and the Captain wondered what would happen to an egg left soaking in water and one left soaking in vinegar. They identified the hypothesis — he thought the water egg would turn into a snowball and the vinegar egg into what he logically called a lava ball (because if there’s a snowball then surely there’s a lava ball, right?). Mommy helped with the handwriting but the scientific drawings are all the Captain’s. I predict a bidding war between John Hopkins and Stanford in about 20 years.
