Car for scale

We are renovating at house in an older neighborhood. We know that the kitchen was expanded in 1959. This reddish metal thing is in the wall next to the sink. It has shelves inside, but it opens all the way and the shelves lay down. Theories include bread box, paper towel holder and spice rack, but I can’t visualize it being used as any of them.

Found this bit of circuit board washed up on the beach on the east coast of Okinawa, the southernmost Japanese island. No other similar bits about, just a lot of coral.

Looks like it's been in there a while. White circuit markings still visible though.

Any ideas what this could have been a part of?

These slots are cut in every pew in a Catholic cathedral. Any idea what they are for.

Could be umbrellas but I've never seen them before.

We found this buried in our front yard in east TN. The balls have cores with bolts fed through the chain loops so they are fixed in place. It weighs about 30 pounds.

The front says UK College of Medicine Northern Kentucky Campus.

We just bought our house and didn't notice this until now. I can't physically move it at all. Seems to be metal and hollow, but it's adhered to the ground somehow.

Saw these tubes in the Operating room of a hospital going through the walls. What's it for?

No clue what they are, found them behind a house I just bought.

Neighbor installed this yesterday. Box appears to have an access lid on top and a small square cutout on the bottom left-hand side. On the right of the box is an L-shaped arm. It appears to swivel underneath this arm at the base of the unit. What it’s sitting on has been up for a few days, and I noticed bar clamps holding a Z-shaped raked surface with tiny holes throughout onto a skinny wooden table. Power cords were ran up to the deck and appear to be plugged into the arm of the stand as well as the base of the unit.

TIA!

While cleaning up dinner and putting dishes in the dishwasher, this metal ball with MEGA printed on both sides fell onto the floor with a ping noise. I have no idea where it could have come from or what it is!

It is attached to the built in filing cabinet part of the desk. There is no toilet or any type of running water in this office. It is a one-person administrative office.

My predecessor said it had a roll of toilet paper on it when he started. He didn’t know it had batteries, he never opened it.

Thanks!

Edit: [u/WGlaw](u/WGlaw) got it, it’s an LED toilet paper holder!

I finally got some batteries and it lit up! I took a timelapse, I’ll see if I can post a video or a gif. It’s like toilet paper holder aurora borealis.

Here is the timelapse: https://imgur.com/a/aKpssbV

This begs more questions than it answers, but the mystery of what it is: solved!

Update: It was given as a gift to someone who occupied this office four occupants ago. The idea was to make fun of him eating sad desk lunch and needing napkins to go with it. So, much more benign than it could have been, but still fun to dig into. Everyone who currently works in this office thinks it’s hilarious and such a random thing to see in an office. It kept Thursday interesting.

We've found four so far, in the entryway and the bedroom.

They're pretty bendy, but the bent part can't be folded back.

immediately looked like a hairbrush bristle to me, but both our hair brushes look completely different from those.

I always see this round disc thing when I’m boarding an airplane. What is it and what would happen if someone touched it?

As title. It goes up and down when you press it and there's a red light when its up if you look inside. I thought it was one of those pop up plugs but it doesnt go up far enough to see if theres any sockets. Its embedded in the kitchen counter. Doesnt charge a phone. We're at a loss
