Sign Language & Communication Tutoring
One-on-one tutoring in communication methods for the deaf and hard of hearing. My father's Visible Speech system, basic sign language, lip reading techniques. My mother couldn't hear me speak, but she could feel the vibrations of my voice through her hand on my throat. Communication finds a way.
Public Speaking Masterclass -- Voice & Persuasion
Small group (max 6). I spent my life studying the human voice -- how it works, how it persuades, how it fails. I'll teach you projection, pacing, and the one trick that separates a good speaker from a great one: silence. The pause before the point is more powerful than the point itself.
Glass Prism Set (Optical Grade, 3-Piece)
Three optical-grade glass prisms: equilateral, right-angle, and porro. The equilateral prism splits white light into its spectrum. I purchased mine from a fair in Stourbridge in 1666. These are considerably better quality. Handle them by the edges -- fingerprints ruin the optical surfaces.
Soil Testing Kit (Professional Grade)
Complete soil analysis kit: pH meter, NPK test reagents, color charts, sample bags, field notebook. Test up to 50 samples. I tested thousands across Alabama. Every farm was different. This kit lets you read the story your land is trying to tell you.
Morse Code Workshop -- The Original Digital Language
Learn Morse code -- the first digital communication system. On/off, long/short, 1/0. In two hours you will send and receive at 5 words per minute. We use a real telegraph key and sounder. Tip: Learn the rhythm, not the dots and dashes. Your ear learns faster than your eyes.
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.
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.
Rocket Engine Test Stand (Educational)
Tabletop test stand for small solid rocket motors. Measures thrust with a load cell and data logger. See the thrust curve, calculate impulse and burn time. I tested engines hundreds of times at my aunt Effie farm in Auburn. The neighbors complained. Worth it.
Orbital Mechanics Tutoring -- Getting to Space
One-on-one tutoring in spaceflight physics. Escape velocity, orbital insertion, Hohmann transfers, gravity assists. I worked this out by hand in the 1910s. Tip: Getting to orbit is not about going up. It is about going sideways fast enough.
Radio History & Maritime Safety Lecture
Wireless at sea: from first ship-to-shore messages to the Titanic to modern GMDSS. 700 survived because Jack Phillips stayed at his post sending SOS until power failed. After Titanic, every ship was required to carry wireless.
Materials Science Workshop -- Polymers & Fibers
Hands-on session. Test the strength of different fibers: nylon, polyester, aramid (Kevlar), carbon fiber, silk. Measure tensile strength, stretch, and failure modes. Understand why Kevlar stops a bullet but scissors cut it. Material properties are not obvious -- you must test them.
