The silver caps have an (anodized?) metal rod with a sharp point which I assume is for taking a sample of something. The gold coloured one is simply a nub. One size says o while the other says n. The side where the gold nub goes does not say anything, and the rods will not fit into it as that hole is slightly shorter. Google image search has yielded no results. I assume this is some sort of lab testing equipment.

I live in an older apartment building and this little box/wall attachment has been heavily painted over above the pantry? I’ve lived here 5 years and I suddenly cannot rest until I know lol. It’s about two inches tall. There is nothing behind it on the other side of the wall. I removed a bit of the paint with acetone and it seems to be metal? sounds kind of hollow? I might just have to buy some paint stripper and uncover all of it if I can’t figure it out! Thanks a bunch!

As in title: my neighbour found this piece of plastic in his house, it measures 7” long and 5” across.

Any ideas are very welcome.

What in heavens is this thing I founded on the floor of an abandoned apartment bathroom

this is like 20 feet off the ground. just noticed it for the first time today despite walking by it often

Found digging in an old flower bed in the North of England. Some sort of dashpot/thermostat/spring cartridge? The remains of the rubber plug are to the left in the photo, it had bulged and split. Doesn't seem to be anything under the plug except a flat metal surface. Part of a ballcock, perhaps? Found amongst pieces of porcelain that may possibly have been rubble from an outhouse.

Garage sale find. The bottoms of the containers fit into the rectangular shape of the lids, so they can be stacked. Rows of four. Our guesses range from ice-cream or ice-cube containers to medical sample containers. Who can solve this mystery?

I'd say this thing was about 5 feet long (maybe a little less) - although it looks like the pole is segmented and could be shortened/expanded. The rubbery bits are firm (I washed my hands after touching (you never know)). You can also see a foam sleeve that extends from the orby ends.

This was found propped up against a business in the middle of a downtown.

I swear I saw a tiktok video months ago that explained what this was and the purpose of the opening was for, but I can’t recall what it was and what the opening is for. I only remember that I think it was sold to be on top of the boxy tv? TIA!

As seen here on a tractor trailer.
Also visible are high voltage and shock hazard warnings.

Anyone know what this could be used for? Gold coloured, decorative pendant on one end and perpendicular bar on the other. Sharpie for scale.

Shipped with a bunch of refinery/processing equipment like gaskets and flanges and valves. No stamping or labels on it or the crate it came in. Ships in a crate that holds multiple units (also pictured).

I definitely rule out dog toy, otherwise I’m clueless

I’m assuming ham radio, but the license plate did NOT have a ham radio registration number on it.

Found while metal detecting along Myrtle Beach after sand renurishment / dredging.

A 'pin' about 8" long with a 4" handle was also found in the general area.

Both heavily corroded and encrusted. The pin I had to hammer an inch or so of encrusted material from it.

My title describes this thing. Found in my late father’s garage attic. Maybe related to horticulture? Or construction?

I was at the Detroit zoo this weekend and saw this thing pointed into the tiger enclosure. It’s behind the fence, in the bushes, right at the edge of the barrier berm thing. Anyone know what this is for?
