It had a strong chemical smell. Left in my house by the previous owner.

I work at a group home, which is an actual residential house that was remodelled to meet CRA standards (not sure if that’s relevant, but just in case). This spot in the house’s basement has always confused me. The sealed door is weird on its own—although I think I have a vague idea abt why it’s there—but I have no idea what the deal is with the square next to it. It’s the same material as the rest of the floor and is flush with it. About the right length and width for me to stand on it with my feet shoulder width apart. There is a mini freezer a few feet away from it, but I think it was installed some time after I noticed the platform. Haven’t noticed anything else running near the platform that I’d associate with needing it, and there are no others like it in the rest of the basement

I saw this thing while I was hunting for deer in the wasatch mountain range near mount nebo. I thought it could be an aircraft fuel tank? I saw a couple F35’s doing fly overs while I was there, probably coming from Hill AFB

Rusted on one side. Edges are smooth.

This item has shown up at our house and no-one knows what it is. Rubbery fixed non rotating chamfered pointed great rubber tip with a white plastic connecting body. No springs within.

Google image search is being unhelpful.

Anyone have an idea?

Sold as paper drill from 1950s, but I can’t find a match online or figure out how it functioned. Was this made as a bit for a drill press? As part of a hand tool? ETA: the short cylinder that “caps” the assembly has two different internal diameters, one that matches the shaft precisely, and one that is larger. This might be a clue to function? ETA: the fixed end is stamped with the number 187; no other markings. Last pic shows the wooden case.

Title describes the thing. Found this outside my work. 7” long. Plastic. One end screws off and there is are LEDs with batteries in that end. Has two notches of different widths cut out on sides.

My local beach cleaning group has collected dozens of these over the past few years. No one can identify what they’re from! (Including various AI chatbots.)

They’re solid plastic, possibly part of a pull tab/ring, and at least some of them seem to have come from Colgate-Palmolive products. Are they from soap? Shampoo? What do they look like on the actual product?

It’s driving me crazy!!

My dad got this at an estate sale. No one there knew what it was or where it came from. The deceased former owner was a world traveler with items from everywhere so that doesn't narrow it down. It's light enough that it's possible it could have been worn with a cord through the holes in both the cylinder and they topper. The cylinder looks to be bone and everything marked on it is etched in. The topper and base are light but solid wood

Found on street in California, in a location where (a) teenagers sometimes hang out and (b) electrical utility work was done. I asked some electrical linesmen and they did not know what they were. I thought they might be cutting or grinding teeth from some machine, but in that case they should be identical, but they are slightly shapes.

Got this from a friend who found it on a beach in South Africa a few years ago. It is very lightweight, dry, fragile, and chalky. Has a fibrous texture almost like gypsum. Google AI suggested some sort of fat blob, but it is not waxy or soap like or greasy. It has a small barnacle attached and seems to be organic not synthetic. Other suggestions from Google are: dried golf ball sponge, dried geodia sponge, or some sort of coral. Would love a human expert to weigh in!

EDIT: this is the first time I’ve ever posted on Reddit and I definitely did not expect it to get this kind of attention! For those of you who haven’t been through the rollercoaster of a comment section, or are concerned about my safety, here’s some more information:
- I received this “gift” in a box of rocks and shells from a friend and I had no reason to even consider gloves at the time, but I thank you all for the suggestion!
- I have never been to South Africa and don’t live near the ocean and thus have very little experience with this sort of thing.
- for those suggesting toilet paper/wet wipes, yes it is possible, but please note that this thing did not burn.
- I’m more inclined to think (and hope) that it is a dried sponge of some sort. I have a jeweler’s loupe and it is very porous and less papery, and some sections look like dense bread

Thank you to those of you taking the time to be helpful rather than calling me stupid and asking me why I touched the thing with my bare hands-I truly had no reason to be concerned (until now).

EDIT 2: solved! User SA_Underwater suggested dried sea sponge, and I am inclined to optimistically agree based on the porous structure (like bread) and the fact that it didn’t burn.

A few other credible users with waste management and experience mentioned toilet paper, fatbergs, and wet wipes. Yes those are disgusting options and no one wants to admit they’ve been displaying toilet paper as decoration for 2 years, but it didn’t burn like dried paper would, and while it had a fibrous exterior, the inside was porous like a sponge.

Thank you everyone!

A friend got this at a flea market because she thought it looked pretty cool, the seller did not know what it was either.

Sinks when placed in what. No matched via Google or AI. Likely marine?

It was bought with a tabernacle from a religious reliques seller.

My father found this in his garage. No idea what it is or where it came from. A bit dusty but overall looks unused

Found this unused part at home in Japan. It looks like a replacement part for some appliance or household product.

- No markings or text on it

- Nothing moves, not electronic

- The round end has two small tabs, like it twists to lock into something

- Small hole goes all the way through

- Inside the rectangular part there are 4 small pins

It may be from an Amway appliance, but I'm not sure.

Any idea what this is?

Found this on a bookshelf while cleaning. It is approximately six inches long, rigid, and attracts a magnet. Both ends are blunt, and the rod has a round cross-section. One end curves into an open loop, while the other bends approximately 90 degrees. It does not appear to be an automobile part. Its location didn’t provide any clues about what it came from because my wife found it in a “catch all” spot. Does anyone recognize its purpose?

Hello! I’m staying at an Airbnb and I’m curious what these are? There are multiple scattered in every room even two like 4 feet apart from each other and very very high up on walls. Since they’re all high this is the best one I could get. Ignore the brown dots on this one as the other ones don’t have that (probably moisture or something).

Maybe about 2 inches long? Not heavy at all. It's been floating around my family's house for years and I only thought about it now. I don't even know who it could've come from.

EDIT: Solved! Cloth clamp for a picnic table.

Two little round plastic knobs I found in a box I was unpacking after a move full of miscellaneous electronic items. These were in a small non-descript white cardboard box and little foam baggie which looks like it's a pack-in accessory for some type of electronic device.

Found in an old tool box. It has some type of grove indented in it.

Indoor cat threw up this piece and I don't know it's source. Yellow, flexible, looks like the tip of something? Doesn't seem to be from the automatic feeder, a toy or a vacuum cleaner.

Any suggestion appreciated!

Solved! Picture of the original part in the comments. Thank all of you for helping! Cat is ok and now it is verified he puked all of the missing piece.
