It was my wife's idea, really. I was teaching at Haverford College (general chemistry, among other classes) one semester and, like many chemistry teachers, I used in-class demonstrations to drive home the "point" of the lecture. This would continue but Practical Friday, we thought, would be something special, done weekly, where I take a step outside of class to point out the greater value of chemistry to science, if not to society. What followed was a combination of whacky (What happens when you want to bake something but don't have baking soda?), resourceful (How do you measure the pH of a solution if you're stuck on an island with only...wait for it... cabbage?), and athletic (Practical Friday: Winter Olympics Edition!).
See you Friday!
