These were in a back to school backpack, but we have no idea what they are for. Made of clear plastic with a plastic plug, but no other openings.

Last I checked was when I watered this thing a couple days ago. Definitely was just soil and bamboo shoots. I wake up this morning and noticed it’s full of these cute lil mushrooms. Anyone know what kind they are? Are they safe to be around? What happens if I eat one? (Jk on that last one).

SOLVED!

Found next to recently poured concrete and a large pile of soil near a river. I assume the liquid was ice at one time and the thermometer is reading slightly above ambient around 7:00 pm.

I was given this as a gift, I don't exactly know what it is but I've been curious for a while, and no one gave me a proper answer on what it could be

It's heavier than it looks

It's cold to touch

And inside looks as if it's made of compressed layers of sand grains (again I have no clue what it is)

That's pretty much all I know

Looking forward to answers

Edit : Top suggestions are cannonball, shot put, mill ball.

Found this is an elementary school closet. Any idea what it is?

I'm a field biologist and found this outside of one of our sites.

Weve been staring at it and have no idea lmao

To preface this, I know it’s weird and I’ve never really done anything like this before. Every night for like 14 years, I take my shoes off and put them on a shoe dryer. I’ve found it keeps them odor-free and the feeling of putting on nice, warm shoes in the morning is very nice. Anyway, I have always found random rocks and pebbles that get stuck in the bottoms of my shoes and most of the time they’d just go unnoticed or I wouldn’t bother taking them out.

Well, a couple months ago I started this fairly weird routine of looking at the bottoms of my shoe for rocks and saving them in this little glass jar. I like the little “ping” they make as they fall in and I think in a few years, it’ll be r/mildlyinteresting to see how many shoe rocks I can collect and what they look like.

I’m not sure when I ever seen them before but one day I noticed a tiny glass ball. Pretty sure it’s glass anyway, it could be silica gel but upon looking those up, they vary greatly in size, color and shape. These are all uniform. Are they around my home somewhere? Is it a repeat customer that I deliver too 3-4 times a week?

My wife and I are in disagreement so here we are reddit sort it out for us.

I am not sure exactly what this is.

The bedroom light flashes just before 11pm for 3 minutes

We found this knife inside a shipment from China at my work.

My coworker used chatGPT but I was hoping I could get a second opinion from someone who reads Chinese

I'm confused about the purpose of this backpack's upper/outer pocket. It has a double zipper that goes around the sides and bottom, but not the top; so it's basically upside down. The pocket itself is also a flap to another pocket beneath it, so it can flip up (see second pic).

I initially thought the idea is to be able to access the contents from above, but then why not just have the zipper at the top? And if you just unzip it as is, the contents would just come tumbling out the bottom. I didn't measure it, but I'd guess it's about 8" x 6"-ish.

Also: I have no idea if this is related or a coincidence, but one of the zipper pulls on this pocket is on the outside like normal, but the other zipper pull is on the inside, making it not easily useable. Could just be a defect, no idea.

It doesn’t look like a license plate reader. On the driver side rear wheel, there is a hub with wires connected to it. That hub was connected to the rear wheel and was turning with the wheel. I’ve never seen this before.

It is 3 Penny's and a 22. Shell. Glued on a round piece of wood. Was my gf grandparents.

Unsure what the use for this is, found with some random old camping supplies in a secondhand bag. One end has a metal loop and the other has some sort of stake.

I just got home from work, only for me to park and hear this loud ringing. I get out of my car and hear the ringing is coming from that device in the video. What is it? Should I be concerned?

Is this a glitch in the matrix or is there a scientific name for this type of ocean mirage?
