We started with a quart mason jar, even before Pintrest filled them with everything.
We added a little gravel straight from the pet shop and a tiny plastic plant. Filled it with water, dropped in Penelope and our dorm room suddenly had one more occupant.
Guests noticed our mason jar aquarium, because things in mason jars were interesting even before Pintrest proclaimed it so.
“She’s tiny and shy” we’d tell them. “She might be down in the gravel, or hiding in the plant.”
So little, she was nigh on invisible our Penelope.
Friends would look and look for her and, occasionally, one would spy her.
An impressive feat, considering she was never actually there.
