Two-hour session with safe demonstration materials. Cloud chambers to see particle tracks, Geiger counters to measure background radiation, mineral samples that glow under UV. You'll understand alpha, beta, and gamma radiation and why each behaves differently. Tip: Radioactivity is natural. You're surrounded by it. The banana you ate this morning was radioactive. Fear comes from ignorance. Understanding comes from measurement.

🇵🇱 🇫🇷 🇷🇺

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.

Hands-on letterpress session. Pick individual lead type from the case, compose a line, lock it in the chase, ink the form, and pull a print. You'll leave with a hand-printed broadside. Tip: Set type mirror-image, left to right becomes right to left. The first time everyone gets it backwards. That's why we call it 'mind your p's and q's' -- they're mirror images in the type case.

Johannes Gutenberg

🇩🇪 🌐

Reading tracks, finding water on the open plains, building shelter from materials at hand, fire making. My people lived on these plains for thousands of years without a single building. The land provides everything if you know how to ask. Tip: Listen more than you look. The wind carries information.

Sitting Bull

🇬🇧

Full-weight cruciform longsword and heater shield. The longsword is 40 inches of straight double-edged steel, designed for mounted and foot combat. The heater shield replaced the kite shield -- lighter, better for mounted lance work. I will teach you the cross-guard parry that saved my life at Jaffa.

Richard the Lionheart

🇫🇷 🇬🇧 🌐

Riveted chain mail hauberk and conical helmet with nasal guard. Lighter than Crusader plate, better in the heat, flexible enough for mounted archery. My Mamluks wore gear like this at Hattin.

Saladin

🇦🇪 🌐 🌐

Chain mail hauberk over padded gambeson, with plate reinforcement at shoulders and knees. Great helm with cross visor. About 55 pounds total. I wore heavier at Arsuf in desert heat. If you can fight in this, you can fight in anything.

Richard the Lionheart

🇫🇷 🇬🇧 🌐

Navigating by stars, moss, river direction, and landmarks in total darkness. I moved hundreds of people through swamps and forests at night with no map. The North Star was our compass. The drinking gourd song was our code. Tip: Move when the dogs cannot track -- in rain, through water, downwind. The night is your friend if you know her.

Harriet Tubman

🇬🇧

Concentric walls, flanking towers, murder holes, killing grounds. I designed Chateau Gaillard in Normandy -- three baileys, each commanding the one below. Philip took it by climbing through the latrine chute. Tip: Design for the attack you cannot imagine, not the one you expect.

Richard the Lionheart

🇫🇷 🇬🇧 🌐

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.

Richard the Lionheart

🇫🇷 🇬🇧 🌐

I spoke nine languages and used every one of them in negotiations. Speaking a person's language is the fastest way to their trust. This workshop covers negotiation tactics, cultural reading, and why the interpreter should be you, not someone you hired. Tip: The person who controls the translation controls the conversation.

Cleopatra VII

🇬🇷 🇦🇪 🌐

Three-day outdoor survival. How the Mongol army traveled without supply lines. Dried meat under the saddle, fermented mare's milk, hunting on the move. Tip: A Mongol rider carries 10 days of food in two saddlebags. Learn to need less.

Genghis Khan
