ESSENTIAL MATERIAL

PETRI DISH

The blob's main habitat
SCLEROTIUM

Inert form of the blob that can be reactivated
AGAR-AGAR

Gelling substance for the substrate
OAT FLAKES

Your Blob's Favorite Food

Start Breeding

SUBSTRATE PREPARATION

Dissolve some agar-agar in hot water, pour it into the petri dish, and let it cool. This will create a gelatinous surface for your blob to move around on.
AWAKENING OF THE SCLEROTE

Place the sclerotium on the agar. With a little moisture and warmth, it will begin to wake up and explore its new environment.
FEEDING

Place some oatmeal near the blob. It will quickly spot them and start eating them.
DAILY MAINTENANCE

Remove any uneaten food scraps to prevent mold. Keep the substrate slightly moist and at an ideal temperature (between 18 and 24 °C).

TIPS FOR OPTIMAL OBSERVATION

TIPS FOR THE MORE EXPERIENCED

CREATE LABYRINTHS

Use non-toxic barriers to observe its movement strategies.
BLOB DIVISION

Try splitting it to share the experience: each part can become a new blob.
