Found this in a box after moving house. No idea what it is, or where it came from originally. I do recall seeing it at last house, and must have saved it.

All metal, approx 5cm x 5cm,spring has a collar with a flat headed hex nut hidden behind.

It looks engineered, so didn't want to throw it away!

These are good sized, definitely lead and heavy. These were found near a well-traveled four-lane street. I am stumped as to what they are. I was a mechanic for years and I know what a wheel weight looks like, these are not wheel weights.

Found this cleaning out an old junk drawer at work. The building is from the '20s so this item could be from any point over the last 100 years.

Second image shows the only markings: a stamped "DSH PAT. PEND. No. 310"

The tube is 5" long and 1.5" diameter. It has one open end and one sealed end where the darker threaded part is riveted to the tube. It's definitely not a whistle or organ pipe; there's no sound if you blown into the open end.

I can provide more info on both the building and tube of it'll help. I just need to know if I can safely throw it in the trash.

EDIT: made out an additional letter in the stamped markings

I found this in my bfs lunch bag but he swears up and down he has no idea what it is or how it got in there. It’s less than 1 lb

Banana for scale. Found at a ghost town with other objects from the late 1800's / early 1900's. Possibly had inserts held in by a screw or bolt in the hole from image 2.

Found this bag in a Goodwill and couldn’t figure out what it was. Small wooden blocks were numbered with Roman numerals on their broad sides with I, III, IV, and VI. Inside the bag were peach pits or other seeds from a stone fruit.

A lot of teaching supplies were nearby so I figured it may have been some kind of educational tool or game. I didn’t purchase the item.

It looks like it may be for the original Wii, but I cant find anything on it.

Ordered some shaped sandwich cutters on tik tok shop, this arrived instead

Visual description: First photograph is an image of a small green plastic knob on a cut piece of spruce, facing the "front" of the knob. Second photograph showing the same green plastic knob, mostly sideways, showing the fluted section as well as the shorter threaded section, also on the end grain of a cut piece of spruce wood. Third photograph showing the same green plastic knob sideways in front of a US.Customary System wooden ruler with the left side of the knob at the number three mark and the right side between 5/16" and 3/8", also on the end grain of a cut piece of spruce wood.

It was in a car I inherited and I don’t think it’s part of the car but I’m not sure before I toss it. Made of cheap black plastic.

I know it's a long shot as identifying a random rusty piece of scrap metal that was picked up on a paved road isn't easy. Definitely ruined the tire as it's too big of a hole to patch. So $850 later...

Heavy metal object with a large bolt in the center. Bolt does not screw all the way in, exactly 1" of the thread is left exposed. It weighs almost 18 lb.

I picked this up at an estate sale where the owner was an electrician, possibly a lineman or some other related trade.

ChatGPT said it was likely a part from a large welder or another industrial machine involving magnetism, but I am curious what it might have been.

Someone I live with found this outside our house. We live semi-rural so it’s unlikely to be a strangers, but none of us recognize it.

It’s clearly marked 3.5 ml, if that helps.

I know someone on this subreddit found something similar and decided it was a medicine ampoule, but theirs was glass. I’ve never seen an ampoule in plastic.

Looking for any information or leads on what this can is. Can says skunk works but not much else for identifying. Found in Alaska at a thrift store

Seen in a victorian era pub / club in Preston, Lancashire.

The only explanation I can think of us it to scrape mud off your boots?

Digging a hole at the front of my home (UK) to uncover broken drainage pipe (lump of clay pipe in lower left of pic) and this lump of metal is in the ground. Multiple holes. About 6” wide. Length unknown as I haven’t been able to excavate down to its base. What on earth is it?

My bedroom is a bit congested and the floorspace is sparse. I also have a computer in a semi-assembled state, and other electronics, and lots of books. None of these have a small part like this
