Long before flowers.
Long before dinosaurs.
Long before the first neuron.
It was already here.
A billion years of evolution. No bones, no skeleton, not a single neuron — and yet it learns, it chooses, it solves mazes. Adopt it dormant, wake it up in 48 h, discover life as it was before Earth invented the brain.
Two sclerotia, two Petri dishes, and everything you need to wake up your first blob.
Four dishes to raise your blob over the long run, and two experiments: the choice and colored diffusion.
Nine dishes and four experiments: the choice, the U-trap, colored diffusion, and the optimal network.
Nineteen dishes and eight experiments, including the maze, the strain race, and the Tokyo network.
No need to be a biologist. A quick soak, a little patience, a whole lot of fascination.
Soak your sclerotium in a bit of water, shake it off well, place it on its agar with a few oat flakes. Within 24 to 48h, it becomes a bright yellow plasmodium that starts spreading.
D0 → D2
For several months, with regular transfers to fresh agar, your blob explores, feeds, solves mazes — with no brain, no neurons. That's what drives researchers around the world crazy.
D3 → months
Heading on holiday? Re-sclerotize your blob. Kept dry and away from light, it sleeps for over a year. You wake it up later. As simple as that.
Unlimited pauseThey devour science documentaries, take everything apart at home, ask 30 questions a day. The blob becomes their new living companion — they watch it pulse, feed it, put it to sleep, wake it up.
See kits for kids →You're looking for an activity that makes a mark, no animal paperwork required. Our kits are designed to fit easily into class: safe materials, clear protocols, and the blob fascinates all ages.
See our kits →You follow Sabine Hossenfelder, you read Nature, you know what a slime mold is. You want to recreate the Tokyo Subway experiment at home and build an optimal network on your desk.
See the Blob Lab Kit →Where humans have 2, the blob has 720. Any type can pair with any other — except its own.
Faced with several food sources, it compares them and heads toward the best — an "intelligent" decision without a single neuron, guided by simple chemical signals.
The blob belongs to the Amoebozoa, one of the oldest eukaryotic groups. Long before dinosaurs, long before the first neuron.
Placed in a maze, it finds an efficient path between two food sources. In 26 hours, it rebuilt a network comparable to Tokyo's rail system, built over more than a century.
In 2021, Thomas Pesquet woke 4 sclerotia aboard the ISS. On the ground, around 2,000 schools ran the same experiment in parallel.
Adopt your own and watch it solve its first maze in under 48h.
Adopt a blob →Send us a photo and we'll ship a replacement sclerotium, free of charge. Your kit already includes at least one backup sclerotium just in case. 100% wake-up guarantee.
From age 7 with an adult, age 10 solo. Physarum polycephalum is not linked to any human infection, and no known allergen or toxicity has been reported. Wash your hands after handling, just like after gardening.
Shipped within 24 working hours. EU delivery in 3 to 5 days by Chronopost International. Rate by weight: €17 (0-200g), €20 (201-600g), €25 (601-1,400g), €30 (1,401-2,000g).
With regular transfers to fresh agar, a plasmodium lasts several months. Without upkeep, a dish holds for a few weeks. You can also re-sclerotize it: kept dry and away from light, it waits for at least a year.
The sclerotium is dormant and dehydrated: it handles normal shipping temperature swings without damage. You can order in July and wake it up in November, no problem.
