Gray, I think it’s supposed to be inserted somewhere. 1.5-2inches deel

Made in Germany, pieces are tapered and pressed together, iron bobbin was with it but now sure if it’s related. What is it?

The bobbin and the wood pieces have clamps so they probably attached to a table or something. Any ideas?

Field of funnels in a clearing?

What is this massive piece of construction equipment, with 2 large appendages and cables running from the outer arms back to the main cab?

I was driving on the I15 in Las Vegas and they are doing construction on the Tropicana overpass. I can’t figure out what the purpose of this would be. It appears to be 3-4 stories tall.

Prism-like hard cube found in the grass of a local park

Found a sealed bag of small threaded plastic sleeves, bolts, and slotted/curved metal tabs in my newly purchased home.

Upon moving in to a new home I found this bag, sealed, in the garage. They obviously all go together for something but I can’t figure out what, and am scared to throw away because I’ll of course immediately realize they were important and I need them. The white pieces don’t expand or move at all when the bolts are screwed in, and yes the bolts fit into the slots in the metal.

Round yellow soft foam honeycomb, 3" diameter and 1/2" thick. Possibly purchased from a pet store. Very light weight. It was placed in a rat's cage, and the chew marks are from the rat. We are worried that it killed the rat and so we are trying to figure out what it is.

Found this small white fiberglass-like tube with a cotton interior today near a foundation. One of them was burned on one end. There were numerous of them and all were very small.

Does anyone recognize this? It’s maybe made of tin or something? Found it while metal detecting in an area that goes back to the 1860s. Has images of a dog, cat, and rabbit around the edge. It is very thin metal and light weight. I’d say it’s about 3 inches in diameter.

Small white boxes scattered throughout conference area in hotel. MAC addresses visible.

Looks like a MAC address on the top left of these little boxes. They were scattered around the conference center of a large hotel. No power sources visible. I'd see one in basically every hallway and conference room. Reverse image search wasn't turning up anything substantial. Thanks!

What is this giant metal thing I’ve seen all over Portland, OR?
