Grow living slime mold (Physarum polycephalum) and dye it into vivid, multi-color patterns. A complete, open-the-box slime mold science & bio-art kit — live culture, food-safe dyes, and tools. No machine required.
Cultured and personally managed by Yewei Jun (10+ years, dedicated lab). Our Physarum has far higher sclerotium quality and post-revival vigor than ordinary slime molds — it grows easily and stays strong even in a bio-printer’s drier, light-exposed conditions, where common strains fail. The dyes were refined over years of repeated testing by Yewei Jun for the richest, most reliable color.
Original design by FunguyLab — from the team behind the light-guided fungal-printing research at SIGGRAPH Asia 2024.
A renowned microbial-fungi and slime-mold science communicator with millions of followers, Yewei Jun has spent over a decade photographing and culturing slime molds and small fungi. Her work has appeared in a UN-award-winning documentary, at the 2025 Fungi Kingdom International Art Festival in Chile, and across major media. She turned full-time to fungi photography and science communication in 2019, and authors popular-science books including My Fungi-Play Diary.
Every hue here is living Physarum — dyed, grown, and photographed. A preview of the colors you can make, created in collaboration with slime-mold photographer Yewei Jun.
Slime mold isn't a plant, an animal, or a fungus — it's a Physarum, a brainless single-celled organism that creeps, pulses, and explores. It's one of the most captivating things you can grow, and with our kit you can dye it into color and turn its growth into living art.
Wake the live culture, feed it, and watch Physarum spread across the substrate within hours — no lab, no machine.
