Hydrogen — Spectra Tee
Made to order — printed and shipped in 2–7 business days.
Four bands of light, set where hydrogen leaves them. The Balmer series is the signature an atom writes as it cools — the same lines astronomers read in distant stars to name what they are made of.
Printed to scale on a black Bella+Canvas 3001 tee, the wavelengths hold their true positions: 410.2, 434.0, 486.1 and 656.3 nanometres, each rendered in the colour it emits. Front placement, soft-hand finish.
Spectra reads matter by its light. This is its first element — the simplest atom, and the one the rest are measured against.
Care is simple: cold wash, inside out, hang dry. We count durability in washes, not adjectives — and if anything about your order isn't right, reach us through the contact form. A real person answers, and we make it right.
Buying it as a gift? If they're into physics, chemistry, or astronomy, they'll read it instantly — to everyone else it's simply a clean, well-made shirt.
