This is amazing, they treat demos as mini-inquiries: predict → observe → explain. I’d like to spin up open, libraries for chemistry and biology with the same spirit (prediction prompts, low-cost kits, failure modes, disposal notes, and paired sims/datasets for no-lab classrooms). If you’ve got experience running Shakhashiri-style demos, PhET-like sims, or school lab safety, jump in—let’s draft the minimal spec and seed the first 10 experiments.

This must be the dream resource of every physics teacher.

I was taught by Freek, one of the authors, in my freshmen year of undergrad physics. Great teacher!
