This is a regular jar of (unlawfully delicious) blueberry jam from Whole Foods.
Regular, indeed - except that the bottom inch and a half (ish) is pure air. And it was completely filled yesterday.
If you look closely, you can see that the contents of this jar only fill the middle half of the jar:
Right now I'm guessing that someone turned it upside down and the lid's seal wasn't enough to keep the jam from sliding down a bit. But I've never had this happen before...
Anyways - just something odd to lighten up your Tuesday afternoon.
