Crop Rotation & Companion Planting Guide
Hands-on session in the garden. I will show you which plants fix nitrogen, which ones deplete it, and how to rotate so your soil gets richer every year. The peanut-cotton rotation saved Southern agriculture. The same principles work in any garden, any climate.
Natural Dye & Paint Making Workshop
Make paints and dyes from plants, clay, and minerals. I was an accomplished painter who made all my own pigments from Alabama clay. Red from pokeberry, yellow from goldenrod, blue from indigo. You will leave with a palette of natural colors and the knowledge to make more.
Telegraph Key & Sounder Set (Working, Brass)
Brass telegraph key and electromagnetic sounder connected by wire. Press the key, the sounder clicks. The same setup that connected America coast to coast. Includes battery and wire. Set up two stations across a room and send messages.
Portrait Painting Lesson -- Classical Technique
Before the telegraph, I was a painter. Studied under Washington Allston and Benjamin West. I will teach you classical portrait technique: underpainting in burnt umber, building up layers, glazing for luminosity. My portrait of Lafayette hangs in the Capitol.
Scientific Observation Skills -- Seeing What Others Miss
Small group (max 4). I will train your eye to notice anomalies. We will examine slides, cultures, and experiments looking for the unexpected. The mould on my petri dish was an anomaly. A hundred scientists would have thrown it away. I looked closer. The most important words in science are not Eureka -- they are That is funny.
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.
Swan-Neck Flask Set (Borosilicate, 3-Piece)
Three hand-blown borosilicate glass flasks with swan-curved necks. The design that proved microbes come from the environment, not thin air. Perfect for classroom demonstrations. Fragile -- handle with the respect you would give a 160-year-old argument settler.
Coherer & Detector Collection (Replicas)
Early radio detectors: Branly coherer, magnetic detector, crystal detector. Each a step in the evolution of radio reception. The coherer -- a tube of metal filings that clumps when radio waves hit it -- is crude and brilliant.
Engine Rebuilding Workshop -- Gasoline Fundamentals
Disassemble and reassemble a small gasoline engine. Pistons, valves, crankshaft, carburetor, ignition. You will understand the four-stroke cycle by touching every part. I built my first engine on the kitchen table. Clara held the fuel line.
Sales Training Masterclass -- Door-to-Door to Empire
Small group (max 6). I trained 20,000 Walker Agents. The secret is demonstration. Do not tell people your product works -- show them. Do not sell features -- sell transformation. I will teach you the Walker pitch: personal story, live demonstration, satisfied customer testimonial, close.
Tide Pool Ecology Kit (Marine Biology Starter)
Clear observation containers, pH strips, salinity meter, waterproof ID cards for intertidal species, and a guide to tide pool ecology. The tide pool is a complete world in miniature. Everything connects. Disturb one species and watch the cascade. This is what Silent Spring was about -- scaled up to continents.
