Faraday Cage (Demonstration Model, Mesh)
Tabletop Faraday cage -- a wire mesh enclosure that blocks electromagnetic fields. Put a radio inside, close the cage, the signal disappears. Open it, the signal returns. This is why your microwave oven has a mesh screen in the door.
Tuning Fork Set (Scientific Grade, 8-Piece)
Eight precision tuning forks covering one full octave. Essential for acoustics experiments, hearing tests, and understanding resonance. Strike one near a piano and watch the matching string vibrate in sympathy. That's how the telephone works -- sympathetic vibration converted to electrical signal.
Signal Encoding Workshop -- Data Compression Before Computers
Small group (max 4). The principles behind Morse code, Braille, semaphore, and other encoding systems. How do you represent complex information with simple signals? How do you optimize for speed and reliability? Shannon formalized it 100 years later. I figured it out by counting type.
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.
Model T Wheel & Brake Drum (Display)
Original-spec Model T wooden-spoke wheel with brake drum. Hickory and elm, 30 inches diameter. 15 million Model Ts built. This wheel design barely changed in 19 years. When something works, do not fix it.
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.
X-Ray Crystallography Demonstration
How we see molecules. I will explain diffraction patterns, Bragg law, and how a flat photograph reveals three-dimensional structure. We will analyze diffraction patterns from simple crystals. Photo 51 was not lucky -- it was 100 hours of exposure with perfect fiber alignment. Technique matters more than equipment.
Braille Reading & Writing Workshop
Learn to read and write Braille. Six dots, 63 combinations, any language. In two hours you will write your name and read simple words by touch. Sighted people benefit too -- it sharpens tactile awareness and spatial thinking.
Oscilloscope (Analog, Teaching Model)
Analog oscilloscope -- a cathode ray tube that draws electrical signals as visible waveforms. See your voice as a wave, see music as patterns. The oscilloscope is the engineer's eye.
Surgical Instrument Set (Educational, Stainless)
Educational surgical instruments: scalpel handles, forceps, scissors, needle holders, retractors, hemostats. Stainless steel, autoclavable. For anatomy study and dissection practice.
Accessibility Design Workshop -- Building for Everyone
Small group (max 5). Think about accessibility from the start, not as an afterthought. Blindfold exercises, navigation challenges, communication without sight. When you design for the most constrained user, you improve the experience for everyone. Curb cuts were designed for wheelchairs. Everyone uses them.
Voice & Delivery Workshop -- Every Syllable Is a Weapon
My voice was my signature. Clipped, precise, weaponized. I teach you to use rhythm, pause, and emphasis to make every line land. We work on monologues from All About Eve and The Little Foxes. Tip: Slow down. The audience hangs on the pause, not the word.
