Sicilian lemons by the kilo from my garden
Two lemon trees with too many lemons. 1 kg for EUR 2, 3 kg for EUR 5. No pesticides, picked when you order.
Sofia's Birthday Cookie Box (Custom Order)
I bake custom cookie boxes for birthdays, parties, or just because. Choose 12 shapes, I bake them fresh with Sicilian ingredients. Vanilla, chocolate chip, or lemon zest flavors. 48 hours notice.
Radiation Science Workshop -- Safely Understanding Radioactivity
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.
Astronomy Night -- Planets, Moons & Stars
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.
Electricity Demonstration -- Kite, Key & Leyden Jar
Safe indoor demonstration of static electricity, Leyden jars, and electrical conduction. We will NOT be flying kites in thunderstorms. I did that once and it was phenomenally reckless. Instead, we'll use friction machines and Leyden jars to generate sparks, charge objects, and understand positive vs negative charge. I named those, by the way.
Bifocal Lens Demonstration & Fitting
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.
Electromagnetic Induction Demonstration Kit
Magnets, copper wire coils, galvanometer, and iron rings. I will show you how moving a magnet through a coil generates electricity -- the experiment that powers civilization. On August 29, 1831, I wrapped two coils around an iron ring and discovered that changing the current in one coil induced current in the other.
Science for Young People -- The Christmas Lecture
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.
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.
Electromagnetic Waves Workshop -- Light Is Electricity
I will demonstrate that light, radio, microwaves, and X-rays are all the same thing. We will measure wavelength and frequency, build simple wave detectors, and see the electromagnetic spectrum laid out physically. Four equations explain all of it. Tip: The universe is more unified than it appears.
Television History & Electronics Workshop
How I built the first electronic TV. Electron beams, phosphor screens, scanning patterns. We will build a simple cathode ray demonstration and understand how 525 lines of light become a moving picture.
Quantum Mechanics for Non-Physicists
Two-hour session. Superposition, uncertainty, wave-particle duality, entanglement using analogies and demonstrations. Quantum mechanics is strange but the most precisely tested theory in science. Your phone uses it.
