What did you learn today?

Did you learn something new today? How did you stumble across the knowledge and how do you plan to use it in the future? Here’s mine.

Vivarium – definition is in the link. I stumbled across it because I was doing research about air plants. I did the research on them because someone mentioned them in this thread .

I also liked discovering the different kinds of vivarium. Like—everyone knows aquarium—but I had no idea that the formal name for an ant farm was a formicarium. I don’t know what I’ll do with this, but it was fun to learn it. Maybe I’ll make a terrarium and put some air plants in it.

I love doing research and randomly teaching myself things. What did you learn today?
