petri dishes

Bacteria growth plates

Petri dishes are shallow, lidded containers used in laboratories to culture microorganisms or cells.

Named for German bacteriologist Julius Petri, they provide a controlled environment for growing bacteria, fungi, or tissue samples on nutrient media.

Figuratively, a petri dish is any environment where something develops or proliferates: Social media has become a petri dish for misinformation.
