Petri dish Christmas ornaments

Is it too early to talk about how much I like these? I hope not.

Please note these are not actual bacteria, but watercolor paintings sealed in resin inside real petri dishes.

  1. It’s just not as fun if there isn’t deadly/nasty bacteria trapped within your petri dish ornaments. Where’s the sense of adventure?

  2. At an MIT art gallery, a conceptual artist asked his or her (sorry, I’ve forgotten the artist) critics to read reviews into a tube connected to a Petri dish filled with growth medium. So their “hot air” containing their own unique bioflora produced interesting patterns growing in the dishes.

    I’d probably have a biology major write the little “curator cards” next to the dishes explaining the significance of the patterns.
