What is this thing?

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

A couple of months ago I purchased a couch and a couple of weeks ago I purchased some covers. Anyone knows what is this bug?

They seem to spin some kind of silk everywhere they go. They seem to be no longer than about 4 mm. I noticed them crawling up things and then dropping down on a line of silk. I've started catching them by putting little sticks up in the air attached everywhere that I find them. They tend to gather at the top of the stick for easy rapture by vacuum.

They are obviously New England Patriot slippers. They appear official as they have the NFL hologram and were sold by FOCO UK

I would like to know more about the year they were sold and any other info. Google searches, reverse image searches yielded no match unfortunately.

This is probably something for spit cooking, but looks like it could have been an amazing torture device lol

It looks so familiar but am unable to find anything about it.
