20 Mysterious Items Identified By Internet Users

There are a lot of items in the world that humans have created. Most of us will not know what even 20% of them actually are. However, satiating such a burning curiosity is easier than ever due to the internet. The subreddit “What is this thing?” (or WITT) is one of the best places to see the internet try its hand at identifying such mysterious items. Here are 20 such interesting attempts:

1. A Ball Of Feathers?

Question: My husband and I heard a big crash at 5 a.m., like something had fallen off the roof. He found this feathery mass on the ground just now.
Answer (by u/hsudude22): Ok, showed this to my wife (ornithologist and zookeeper of 15+ years). The inside vary likely has fly eggs on it and the feathers are likely from a duck (down in the cut away section gives it away). But she has never seen a feathered mass grown off of a bird like this. So possible tumor that got pinched off the main body?

2. A Cloth Case?

Question: What is this padded satin item with ribbon ties and a hole in the middle? Appears possibly handmade, like a case for a beauty item.
Answer (by u/HelenAngel): It looks like it might go on top of a hanger (which is why there’s a hole in the middle). This would turn something like a smooth wooden hanger into one of those hangers with a satin finish/top to prevent light items like slips or lingerie from slipping off the hanger. The ties would be to secure it to the hanger perhaps. Just a guess though!

3. Weird Spring

Question: Found this on the beach, it’s less than a foot long and seems to be a string with a bunch of little discs strung on it?
Answer (by u/Rexlove): Those are Whelk Egg Cases!

Question: Hollow small glass object with weird opening. What is it?
Answer (by u/GrannyFantastic): Looks like a bud vase. One hole, yes? If so, not a smoking pipe of any sort. Seems like I had one similar, years ago that I got at a little flea market.

Question: What is this bubbling out of the ground in my yard? Purplish metallic gooey inside. Keeps bubbling even if I dig a thin layer down with a shovel.
Answer (by u/connorddennis): Carpenter here, that looks all the world to me like expanding foam. The manufacters like to color them for brand recognition or purpose identification. All the signs are there. The even coloration, the outer skin that formed, and the farmiliar random expansion pattern. Because commercial construction crews can be sloppy, its not far fetched at all that a FrothPak or more likely a case of cans were buried and have had just enough time to rust open. The timing of the construction and its appearance in your yard almost confirms it.

11. Metal

Question: Found in a house we just bought. Made of metal and screwed into the wall, has a hole in the middle. Located in bathroom by shower. WITT?
Answer (by u/Argercy): It’s a toilet paper roll holder and it’s missing a part. I have the same one in my bathroom.

Question: Thin metal circle with Radio Shack branding, found with vinyl record player accessories. Says “Brilliance”
Answer (by u/diakked): It is the plate that went behind a knob on an old stereo or radio. You could turn up the “brilliance.” If I recall correctly, that was sort of like just increasing the treble.

13. Dull Pin

Question: Found in house during a remodel. It’s six inches long with a stone on the end. Google image search says it’s a pin but the end is dull. Any ideas?
