Do you happen to have any My Little Pony figurines to put in the jar?
I fill mine with plaster of Paris and cast…oh, yeah I mean, beyond that I don’t know what else.

I have a co-worker who just started pickling his own eggs. He boils and peels them, then puts them in a jar with 1/3 water, 1/3 white vinegar, 1/3 apple cider vinegar, 1 tsp sugar and some pickling spices. I’ve seen him eat an entire jar for lunch, which makes me grateful my desk is far away from his.
