    The Barf box is about what happens when systems overload and nature decides, nope, not today. It’s the glorious undoing, the point where order collapses into sludge, and somehow, against all reason, something stunning crawls out of it.

    The Barf box contains these items and an info card:

    • Owl Pellet: The owl’s polite little confession. After digestion, what remains—fur, bones, teeth—is pressed and expelled into a perfect gray knot. Crack it open and you’re holding a crime scene of the food chain, a tidy record of violence wrapped in velvet. 
    • Obsidian: Lava that lost its temper. Obsidian is molten chaos spat into glass—atoms too panicked to organize, forever trapped mid-eruption. It’s the Earth’s sharpest apology: black, glossy, and still humming with the heat of its own regret. 
    • Radioactive Honey: Bees, the apocalypse’s sweetest alchemists. After atomic bomb testing, they pulled cesium-137 from poisoned soil and spun it into glowing nectar. Every drop is a sugary eulogy—fallout disguised as gold, proof that the world’s prettiest chemistry can still hum with decay.

    Mini Matter is the smaller version of our Matter subscription box. These kits explore the stuff that makes up our world (and beyond) through surprising connections. Shop the full collection here.

    WE TAKE SCIENCE SERIOUSLY

    You deserve better than craft store science products. And we think learning is more impactful when you're holding a tangible piece of what you're learning about. That's why Stemcell exists.

    We're dedicated to providing the best scientific products available—whether they're fragments of scientific importance, experimental activities, or just interesting things that scratch your curiosity itch.

    With every new product launch, our list of new ideas gets longer rather than shorter. So check in often for our latest projects, and thanks for being a part of our endeavor to make the world a smarter place to live.

    Believe in yourself; for everything else, there's science.

    — TERRY MUDGE, FOUNDER & SCIENTIFIC DIRECTOR
