My brothers and I filled a huge pickle jar with these and some water with the intent to let them sit for a few weeks to see how big they would get. We put them in my brother’s closet and promptly forgot about them for ~5 or so years.

Something was growing in the jar and the built up pressure popped the lid, spilling a bunch of shit all over. The smell never quite left his room
