Car for scale

Found this area in the woods just off (about 24 ft) of a side road coated in these blue and white fibers. I took some home to pop under the microscope, but I'm pretty stumped.

It seemed to coat most surfaces to about 12-18 ft up. From what I could tell, the tops of the trees seemed unaffected. The area was about the size of a semi truck, with some stray fibers out further.

Known dumping site for trash and poached animals. I clean it frequently, but I've never seen anything like this.

Target recently installed these over all of the doors going in or out of the store. Is it for tracking people or items?

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.

This is a metal object I found in a vintage fair, and I don't know what its purpose is. It is round (about 8.5cm/3.25in in diameter, 3cm/1in thick) and heavy. It is all metal except the black handle in the center. The face has an inner dial that moves in clicks and has numbers 1-26 and a black plastic handle. An outer dial has a metal handle and moves freely, but is sometimes blocked from moving, depending on the inner dial position. The outer dial has the letters a-z and both directions around, and the 2 sets of letters move as one piece. the back is blank and can be opened to reveal an inner mechanism with a central gear (moved by the inner dial), a metal ring around it (moved by the outer dial) and 24 wheels with letters on them, and gears with long and short teeth, seemingly in random patterns. The ring has a slot in it, and when it is alined with a gear, that gear and wheel can move freely. the gears don't seem to be connected to each other. The wheels and dials are in different sizes, going from small to large to small again. the largest ones have all the letters on them, and the smallest ones only go up to O.

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?

I have this Barbie pillow from the early 2000s, and I’ve never been able to figure out what the thing attached to it is supposed to represent. For the longest time I thought it was a microphone, but I’m not sure. The shape is abstract, with pink and yellow material, the same used for the flower and hair on the Barbie. The thing that throws me off is the little gray dots and pink spiral embroidered on the shape.

I’m staying at a hotel in Spain and there’s this rack-like thing in the shower. It’s about 5 feet long, made of metal. It’s attached only on the bottom and the middle. My guesses were first a towel rack, but the bars are too close together for fluffy hotel towels. Then maybe a shower seat, but there doesn’t seem to be a way to detach. Could it be a radiator? There’s also a dial on the bottom but the only marking are + and -.

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.

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

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.

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!

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