Just taste it!
If you have to ask yourself whether something is edible, nine times out of ten, they’re not. To be completely sure, the OP decided to take a picture of these jelly-looking objects and post them on Reddit. Hopefully, someone could tell the OP whether it was safe to consume these things.
It was. Someone said that these are juice pouches that you drink from by snipping off the top. However, nobody knows for certain how long they were in storage, so it would probably be a good idea to toss them out. Maybe that the OP drank them, and that’s why we haven’t heard from them since.
