This old XP computer is a nostalgic gem that still runs smooth. Great for light office work, retro gaming, or teaching kids about computing history. I’ll make sure it’s clean and functional before you borrow it.

I grew up in these roads. Tell me how many days and what you like -- beaches, ruins, wine, or all three -- and I'll plan your route with campsites, wild spots (shh), best restaurants, and fuel stops. Includes offline maps and my personal phone number for when you inevitably get lost in Segesta at sunset.

Premium sunglasses for rent. Perfect for beach days, weddings, or looking important at cafes. All authentic (wink). Cash preferred, no receipts needed. Return policy: flexible. Questions about serial numbers: unnecessary.

I've been baking Sicilian cookies for 20 years. Amaretti, biscotti, chocolate chip -- the real recipes, not the shortcut ones. My kitchen, my rules, my playlist. Full day course: 8am to 6pm. You bring the appetite, I bring the flour. Currently mentoring Sofia Ferretti -- she's 17 and already better than me at biscotti. Next class: Saturday March 7, 2026.

Handheld RF spectrum analyzer. See the invisible: WiFi signals, Bluetooth, cellular, radio stations -- all visualized as peaks on a frequency display. I spent my life thinking about how radio signals move through the air. This tool lets you see what I could only imagine.

Hedy Lamarr

Cast iron replica of the Pennsylvania Fireplace. More efficient than an open fireplace -- the baffle system circulates warm air into the room instead of up the chimney. I refused to patent it. Some things should be free. The Governor of Pennsylvania offered me a patent; I said no. Heat is a public good.

Benjamin Franklin

🇬🇧 🇫🇷

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

🇬🇧 🇫🇷

My violin. Well, a replica of my favorite one. I named the original Lina. Mozart and Bach -- that's what I play when I'm stuck on a physics problem. The music reorganizes my thinking. If you can play, borrow it. If you can't, I'll give you a beginner lesson. Badly. I'm a better physicist than violinist.

Albert Einstein

🇩🇪 🇬🇧 🇫🇷

Working replica of a 15th-century screw press, scaled to tabletop size. Wooden frame, iron screw, leather ink balls. Comes with a starter set of lead type (Textura blackletter) and oil-based ink. Print your own pages. The same mechanism that ended the Dark Ages, now in your kitchen.

Johannes Gutenberg

One-on-one mentoring for women and girls pursuing science. When I applied for a lab position, I was told there was no room for a woman. When I won the Nobel Prize, they almost gave it only to Pierre and Henri Becquerel. Pierre insisted my name be included. Find allies. Document everything. Let the work speak. The work always speaks loudest.

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.

Johannes Gutenberg

Small group (max 5). I'll teach you how to do thought experiments: isolate a problem, strip it to essentials, follow the logic to impossible conclusions, then ask why they're impossible. This is how I found special relativity. This is how you solve any problem where the conventional answer feels wrong. Bring a notebook. Bring a problem. Leave with a new way to think.
