I bought one of those air plants in a bottle from a big box store about two weeks ago. After learning more on this subreddit I gently got them unglued and generally they’ve been doing well.
But I have no clue what the white/off-white shell thing is. Today I noticed it’s been moving. The first picture is from today. Second picture is from last night after I misted the inside of the bottle. The third picture is from the day I bought it. The shell is clearly opening and closing. But is it alive? Is it just a coincidence based on humidity? What is it?
