Electricity Demonstration -- Kite, Key & Leyden Jar
Safe indoor demonstration of static electricity, Leyden jars, and electrical conduction. We will NOT be flying kites in thunderstorms. I did that once and it was phenomenally reckless. Instead, we'll use friction machines and Leyden jars to generate sparks, charge objects, and understand positive vs negative charge. I named those, by the way.
Typography & Book Design Masterclass
Small group (max 4). Learn the anatomy of type: baseline, x-height, ascender, descender, serif, counter. Learn leading, kerning, and justification. I'll show you why the Gutenberg Bible is still considered one of the most beautiful printed books 570 years later. Spoiler: it's the margins.
Bifocal Lens Demonstration & Fitting
I got tired of switching between two pairs of glasses -- one for reading, one for distance. So I cut the lenses in half and combined them. Revolutionary? No. Practical? Enormously. This workshop covers basic optics, lens grinding principles, and why bifocals work. Tip: The best inventions solve annoyances, not emergencies.
Cloud Chamber (Wilson Type, Desktop)
Desktop cloud chamber that makes radioactive particle tracks visible. Pour in isopropyl alcohol, cool the base, and watch cosmic rays and natural radiation leave vapor trails in real time. It's like seeing the invisible forces that pass through your body every second. Mesmerizing and educational.
Chemistry Lab Fundamentals -- Precision & Safety
Small group (max 4). Proper lab technique: titration, crystallization, fractional precipitation, safe handling of chemicals. I'll teach you the way I learned at the Sorbonne -- hands on, precise, no shortcuts. You will weigh to four decimal places. You will label every beaker. You will keep a proper lab notebook. Sloppiness in a lab kills people. I should know.
Scientific Method Workshop -- Question Everything
Small group (max 6). Hands-on experiments: pendulums, inclined planes, falling objects. We'll replicate my actual experiments from the 1600s. You'll learn to form hypotheses, design experiments, collect data, and draw conclusions. Aristotle said heavy objects fall faster than light ones. I proved him wrong. You'll prove him wrong too, with your own hands.
Relativity Explained -- Thought Experiments for Everyone
Two-hour session. No equations (well, one equation). I'll explain special and general relativity using the same thought experiments I used to discover them. Riding a beam of light. Trains and lightning strikes. Falling elevators. If you can imagine it, you can understand it. Tip: Relativity is not abstract. Your GPS uses it. Without relativistic corrections, your navigation would be off by 10 kilometers per day.
Underground Railroad Seminar -- Building Resistance Networks
How to build and operate a clandestine network. Safe houses, codes, route planning, compartmentalization (each station knows only the next), vetting members. The Railroad operated for decades under the noses of slavers and federal marshals. Tip: Trust is your most valuable and most dangerous resource. Verify before you trust.
Zulu Warrior Fitness -- Barefoot Conditioning
Barefoot running, shield drills, stick fighting, distance marches. My impis covered 50 miles in a day on bare feet and arrived ready to fight. Modern shoes made your feet weak. This program fixes that. Tip: Pain is information. Listen to it, then decide what to do with it.
Courage Under Fire -- Leadership When Failure Means Death
When the penalty for failure is death -- for you and everyone depending on you. Decision making under extreme pressure, keeping groups calm, dealing with fear and doubt. I never lost a single passenger on the Railroad. Tip: Fear is natural. Paralysis is not. Decide and move. A wrong decision made quickly is better than a right decision made too late.
Geiger Counter (Professional Grade, Calibrated)
Professional-grade Geiger-Muller counter, recently calibrated. Detects alpha, beta, and gamma radiation. Includes headphones for the characteristic clicking sound. When Pierre and I first heard the clicks from our radium sample, we knew we had something the world had never seen.
English Longbow (Yew, 120lb Draw)
Six-foot yew longbow, 120-pound draw weight. The weapon that would later destroy French chivalry at Crecy and Agincourt. Even in my time, English and Welsh archers were devastating. I was killed by a crossbow bolt at Chalus -- never underestimate ranged weapons.
