petri dish
Lab culture vessel
A petri dish is a shallow circular dish with a loose-fitting lid, used in laboratories to culture microorganisms or cells.
The transparent container allows observation while protecting contents from contamination.
Figuratively, any environment where something develops or is tested: Social media has become a petri dish for misinformation.
Named for German bacteriologist Julius Petri. (Capitalized Petri dish is an alternate form.)
