Just FYI

If you turn a jar of applesauce upside down in your fridge so that the last little bits will be easier to get out, and it gets pushed to the back of your fridge and you forget about it for several months, and then you discover it and think that it's really gross and open it so you can pour it down the sink and recycle the jar, it may just explode forcefully and send fermented applesauce all over your kitchen.

Just thought you'd like to know.
