What is this thing?

These are spaced about every 300 meters next to the trail in Memorial Park in Houston, TX, but they aren't only along the trail. They are throughout the park. Does anyone have an idea what they might be? Thanks!

Oh, and it's LARGE. That's my range it's sitting on, and it covers about 2/3 of it.

A friend of mine just sent me this picture and said someone they knew just got a capybara. I informed them that that definitely isn't a capybara. Now neither of us know what it is. It kinda looks like it's in the uncanny valley of the rabbit species. Is it just a fucked up looking rabbit?

I saw this at a music venue. It was strapped onto railings above the audience facing the stage. Says "kick out", is attached by zip ties, looks like a tube wrapped in a durable plastic coat, and looked like it might have a wire running to it.

I bought this at an estate sale. I'll burn votive candles in it. The repaired crack was already there when I got it. I bought it for a few dollars.

What is it though?

There's a baby possum that's kind enough to be a regular visitor where I am. Poor kid has what appears to be a wound on his/her face, almost like a cleft lip. I am no veterinarian, but a "code of honor" relevant to my hobby here casts a shadow over me and I was wondering what kind of issue the disfigurement represents so I don't feel guilty.

Kind of looks like a glossy, all-black bumblebee. Location is Germany.

About 1.5 to 2 inches across. Found in Santa Cruz, CA

Edit: Thanks all for your responses!

I'm going to convert my computer chair from pneumatic to static. I'm currently using plastic clasps that are held on with jubilee clips, but they're not great and need replaced (I'm a heavy lad). A sturdy metal version would be better.

I'm assuming the plumbing world would have something like this, but the language of the plumber is arcane and inaccessible to regular goombas like me. What do I type into the search box?

Cheers!

Found this spider in Assen(NL) can anyone identify it?

Small metal object with clip on top. Clip spins around the object body and can be attracted to a magnet (so made of steel probably). Object body does not react to magnet (so made of brass maybe). Cone shaped tip seems to be made of some kind of plastic.

Found this in my back yard, probably from something I was working on, but it doesn't look familiar.

What is this thing? (Identification may help me fix something I don't know is broken!)

Yeah I know these are used for counting vehicles but can they also be used for detecting vehicle speed?

Description: two pneumatic hoses, affixed to a road. They lead to a box that's locked to a telephone pole. Location is southern California. On a minor artery road.

Doubtful that it's to survey if a new stop sign is needed since the next street is minor, dead ends into this one and already has a stop sign. The next intersection with another minor artery already has a stop sign.

Extremely doubtful that a traffic light is being considered since there isn't anywhere near the amount of traffic to justify one.

This is located on a slope. Many cars speed down here. That's why I'm wondering about speed sensing by this device.

I’ve seen lizards running around in the garden but these seem pretty big imo like 1-2cm

I’ve also seen a 4ft long California king snake

This is outside my apartment building, next to the car park. Is it a connector for a hose of some kind?

Pacific Northwest, southern Washington. Found during a walk in the woods
