Two items I cannot identify. The first one I found somewhere ages ago. It is a roughly 15mm long cylinder of glass, with metal caps at each end, and a taut metal wire running through the center of the cylinder. Best picture I could get. What is this thing?
The other one stands in an area where I sometimes go for runs. This area has a driving range, tennis courts, a miniature golf course and so on in addition to the various running tracks, so I’m assuming this is some form of sports paraphernalia. It is a “cage” of chains, with a metal wire basket underneath, all situated on a pole. The top holds a small sign, but if it ever had a symbol of some sort it’s gone now. The top of the sign is slightly below my height, say 165cm.
If I had found it out in the wilderness, I would have assumed it was a holder for food for deer or something similar, but there’s a tremendous shortage of deer in this sporting area.
I will elaborate on the fuse. It would have been common in electronics, and automobiles. Blade fuses are used in autos now. You still have a good chance of finding them in electronics.

About the frisbee golf hole… there are a few of these, scattered (seemingly) randomly throughout the area. Would you play one, go to the next one, and so on? If so, I’ll have to look for signs showing the way, 'cause I haven’t seen any and they aren’t within visual range of each other.
To give you half a chance of getting the Frisbee to actually land in the basket. Without the chains to slow it down and direct it into the basket, it would simply bounce off the pole.
The chains are for catching the frisbee and allowing it to slide into the basket (otherwise you would have to make the disc land on a small horizontal surface, which is rather difficult.)
It looks to me like the sign on the frisbee hole says (just barely) “2”. As in, it’d be hole 2 of the course. So it’s probably relatively close to some convenient location like a clubhouse or a parking lot, with others further away.
In actual practice, most disk golf just uses trees, telephone poles, or similar objects, and the players all watch to see if you hit it, so you don’t need to “catch” it. This has the advantage of not needing a set “course”, and can be played in any old park or college campus.
