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.
Complete Mechanic Tool Set (Metric & Imperial)
Full mechanic tool set: wrenches, sockets, screwdrivers, pliers, torque wrench, feeler gauges, timing light. Quality tools are an investment. Cheap tools break at the worst moment.
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.
Field Naturalist Kit (Notebook, Loupe, Guides)
Waterproof field notebook, 10x hand loupe, regional plant and bird identification guides, collecting vials, and a lightweight shoulder bag. Everything you need for a day of serious nature observation. My mother gave me a similar kit when I was eight.
Chemistry of Energetic Materials -- Safe Demonstration
Safe demonstrations of exothermic reactions, combustion chemistry, and energy release. No explosives -- but you will understand why nitroglycerin is unstable and how adding diatomaceous earth makes it safe to handle. The chemistry of energy storage and release underpins everything from batteries to rockets.
Color Theory & Photography Demo -- First Color Photo
In 1861, I produced the first color photograph by combining three black-and-white photos taken through red, green, and blue filters. I will demonstrate the principle. Every screen you look at uses this method. RGB. Three colors make a world. Includes hands-on experiments with color mixing and filters.
Element Sample Collection (Safe, 30 Elements)
Thirty element samples in labeled vials: iron, copper, tin, sulfur, silicon, carbon (graphite and diamond chip), aluminum, zinc, and more. Each labeled with atomic number, weight, and properties. Hold the building blocks of the universe in your hand. Some are shiny, some are dull, some are gas in sealed ampules.
Woodworking Jig & Fixture Building
Build a jig that produces identical parts every time. The jig transfers skill from craftsman to tool. A skilled worker makes one perfect piece. A jig lets anyone make a thousand.
Metal Filing & Fitting -- Hand Precision
Before machine tools, precision came from hand filing. File metal flat, square, and to dimension using a file, a square, and a surface plate. Patient, precise, and deeply satisfying.
Complete Filing Set (Swiss, 12-Piece)
Twelve Swiss-pattern files: flat, half-round, round, square, triangular, and knife -- in bastard and smooth cuts. Plus a file card for cleaning. Fundamental metalworking tools. With files and patience, you can make anything.
Sterile Technique Workshop -- Infection Prevention
Hands-on aseptic technique: surgical scrub, gloving, draping, instrument sterilization, wound cleaning. Before carbolic acid, half of surgical patients died from infection. Surgeons operated in frock coats stiff with dried blood.
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.
