I heard a whizzing sound and this landed on my roof. Didn't sound like a bottle rocket, much quieter. Google image searched but wasn't able to find an answer. Closest thing was a mosquito dunk but this is much smaller.

We just moved house and these were in plastic so they’ve never been used. Google searches come up blank.

My husband and I just found these in my mother-in-law‘s basement. Some of them have limited attached like a makeshift Hanger. There are about 100 of them. You can see the full selection here. There are no grooves on the sides. They are 2 1/2 inches across.

Live with 2 kids. Maybe from a game? Also a gardener and an electrician in the house.

Found this metal rod while we were camping at a drive in car camping site... it's about 11 inches long and looks like a little hammer, but has a hole on the hammer head part.

i found this at goodwill earlier today with nothing nearby that seemed related, it fit in my hand so maybe like 3 or 4 inches??? it was thicker at the back and tapered, had a small antenna with visible copper inside. and a crescent shaped groove on top that looked purely aesthetic, no buttons knobs screens speaker grilles NOTHING, the left is what it looked like from the back and the right is a top view

Comes with napkin rings, candle holder, salt and pepper but I just can’t figure this one out.

Found this at an estate sale. There weren't a lot of specialized tools or hardware at the sale, and this was in the attic separate from the tools that were there.

It stands about 18" tall and the sides of the V are about 6" long. It seems base and rod might have been added to the clamp piece and aren't part of the original design.

The clamp piece is precision engineered. The only moving part is the spring mounted clip on each side. They are under moderate tension and lift about 1/16" enough to get some kind of band or strap through. There is a machined line near where the z-shaped piece lifts up, almost as if something is supposed to be cut, folded, or pinched there.

Google image search and ChatGPT haven't produced any concrete results.

Any help would be appreciated!

The other pictures show the sides. I believe it was thrown away due to the nick circled in photo 5. One friend of mine suggested it may be some sort of fuel injector.

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!
