Fermentation Science Workshop -- Grapes to Wine to Vinegar

Hands-on. We will ferment grape juice, observe yeast under the microscope, test for alcohol and acetic acid. This is how I started -- wine merchants of Lille asked why their fermentations kept failing. The answer was contaminating microorganisms. Clean your equipment. Always.

Germ Theory Demo -- Swan-Neck Flask Experiment

Replicate my famous experiment. Two flasks of broth: one open, one with a swan-curved neck. The straight one spoils. The swan-neck stays clear for years. I still have flasks from the 1860s that are sterile. This experiment ended the debate on spontaneous generation forever.

Pasteurization Kit (Home Dairy/Brewing)

Everything to pasteurize milk, juice, or homebrew: precision thermometer, stainless steel pot, timer, instructions. Heat to 72 degrees Celsius for 15 seconds, then cool rapidly. Named after me, and I am proud of that. This process saves millions of lives every year.

Microscope Slide Preparation Workshop

Learn professional slide prep: fixation, staining (Gram, methylene blue, crystal violet), mounting, labeling. Proper staining is the difference between seeing nothing and everything. Techniques from the Pasteur Institute.

Electrical Engineering Tutoring -- AC vs DC

I'll explain why alternating current won the War of Currents and why Edison was wrong. We cover electromagnetic induction, rotating magnetic fields, and power transmission. No prior knowledge needed -- just curiosity about why the lights come on.
