We invented cars out of marshmallows, peanut butter play dough, crackers, and other edible odds and ends. We took pictures, and then we ate them of course!
And in case you were wondering, it was in1672 that Ferdinand Verbiest from Belgium built one of the first cars (both Leonardo da Vinci and Isaac Newton drew plans for ones earlier).
Then came a few of "Miss Olivia, take a picture of this!" (And a bonus: they invented umbrellas all on their own!)
After cars we talked a little about the piano (first built by Cristofori in 1710) and then the jigsaw puzzle (invented by Soilsbury in 1767).
We also talked a bit about the calculator and the triangle invented by Pascal. Pascal invented the first calculator in 1642 when he was about 18! Amazing. I'm certainly learning a lot, and I think the girls are having fun! : )
