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.

Michael Faraday

🇬🇧

Hands-on with specimens. Variation within species, selection pressure, adaptation. The fittest does not mean strongest -- it means best adapted. We examine bird beaks, shell shapes, and seed dispersal.

Charles Robert Darwin

🇬🇧

Hands-on session. Iron filings on paper over magnets -- watch the field lines appear. Compass needles deflected by current-carrying wires. Electromagnets lifting iron. I will explain how electricity and magnetism are two faces of the same force. James Clerk Maxwell later wrote the math. I gave him the experiments.

Michael Faraday

🇬🇧

Brass pocket compass. When I was five years old, my father showed me a compass. The needle moved without being touched. Something invisible was acting on it. That moment -- the mystery of the invisible force -- started everything. Give this to a curious child and watch what happens.

Albert Einstein

🇩🇪 🇬🇧 🇫🇷

A demonstration-rich science talk designed for children and teenagers. I started the Christmas Lectures at the Royal Institution in 1825. Fire, ice, magnets, sparks, bubbles -- real science made visceral. No equations. Just wonder. The Chemical History of a Candle -- six lectures explaining all of chemistry through a single burning candle.

Michael Faraday

🇬🇧

Guided nature walk focused on observation. Collect, label, and preserve specimens. My method: observe first, classify second, theorize third. Most people skip to theory. That is why most theories are wrong.

Charles Robert Darwin

🇬🇧

My most beautiful invention. 37 glass bowls mounted on a spindle, turned by a foot pedal, played with wet fingers. Mozart and Beethoven both composed for it. The sound is unearthly -- people fainted at performances. Some thought it caused madness. It doesn't. It causes wonder. Handle with extreme care.

Benjamin Franklin

🇬🇧 🇫🇷

Make your own oil-based printing ink from linseed oil, soot, and pigments. Water-based ink was fine for stamps but terrible for type -- it beaded up on metal. I had to invent a new ink. You'll leave with a jar of ink good enough to print with. Wear old clothes.

I got tired of switching between two pairs of glasses -- one for reading, one for distance. So I cut the lenses in half and combined them. Revolutionary? No. Practical? Enormously. This workshop covers basic optics, lens grinding principles, and why bifocals work. Tip: The best inventions solve annoyances, not emergencies.

Benjamin Franklin

🇬🇧 🇫🇷

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.

Evening observation session (weather permitting). I'll show you Jupiter's moons, Saturn's rings, the craters of our Moon, and the phases of Venus. Bring warm clothes. Tip: Your eyes need 20 minutes to adapt to the dark. No phone screens. Learn the constellations first, then use the telescope. Context before magnification.

Galileo Galilei

🇮🇹 🌐

Complete alphabet in Textura blackletter -- the typeface of the Gutenberg Bible. Upper and lower case, numbers, punctuation. Cast in traditional type metal (lead-tin-antimony). Each piece hand-finished. Handle with care; lead is toxic. Wash your hands after use. I didn't know that part.
