Curiosity isn’t a sin, so long as you don’t go poking your nose into spooky dungeons and haunted fortresses without preparation. I firmly believe that curiosity and the bright-eyed search for knowledge are what truly make us human. Many of us are willing to put our ego and pride aside to ask for help when we’re stumped. Even more fortunate still is that the world’s chock full of people willing to lend a helping hand.
That is where the popular ‘What is This Thing’ online community comes in. A subreddit that’s home to nearly 2 million members, r/whatisthisthing helps people identify mysterious artifacts and peculiar-looking items, wherever they might be found. They’ve got a great track record and it sometimes feels like there’s nothing that their collective wisdom can’t figure out. Either that or they’ve got an endless supply of Scrolls of Identification hidden somewhere safe.
Today, we’re featuring the subreddit’s best recent posts. We’re pretty sure that these will awaken your inner sleuth, not your inner sloth. Scroll down, upvote your favorite pics, and let us know in the comments if you’ve got any bizarre unidentified items at home. In the mood for more amateur detective work? Don’t sweat it, Bored Panda has got it covered. You’ll find our previous articles about r/whatisthisthing right over here, here, and here.

#1 Posts With Nets On Top On Side Of Street In The Netherlands
Answer: these are to help bats orientate themselves, until the trees are larger. Did they recently cut down trees along this road? Bats need to hear reflection of their sound to know where they are going. These things will replace the leaves in that.

#2 Weird Glass Ball, Suspended By Screws, In A Metal Frame, Bronze Or Gold Colour In Appearance
Answer: It is a Campbell-Stokes sunshine recorder. You place a strip of card into one set of grooves in the piece that curves behind the sphere, point the opposite side of the sphere towards the equator, and the sphere will focus the sunlight to burn a track on the card. The card has hours marked, and more the card is burnt, the brighter the sunlight was.

#8 Ammunition With A Weird Shiny Tip, Could Be 30mm? Worried If Inert Or Not. Found On Glacier In Swiss
Answer: Artillery expert here
What you have there is a projectile from the 35x228mm Oerlikon Flab Kan 63/90 (Same gun that is on the Flugabwehrkanonenpanzer Gepard).
From the fact it has an aluminium dummy fuze (the large cutouts make it obvious there is not enough space for the fuze mechanism) and it looked like it was painted bluish-grey, that makes it an “Übungsgranate” – a Target Practice shot. Be advised that doesn’t mean it’s inert, because even a TP shot can have active pyrotechnic devices like tracers and I can’t see the bottom of it.
My advice, is, as always, call EOD (Explosive Ordnance Disposal, AKA the “bomb squad”) and they’ll sort it for you, because you don’t do demining over the internet.

#9 Found Inside A Musical Instrument, It Is The Size Of A Big Grape But There Aren’t Any Holes Big Enough For It To Have Fallen Inside

#12 Trunk Full Of Chemicals In 1920’s Home, What Is It/For?
Answer: It says “International Correspondence Schools” which still exists.
Probably a course on chemicals?
Now, be careful. Chemical regulations in the 20’s were not the same as now. Based on your pictures, you could have nasty toxic chemicals that can go through a glove and kill you (the mercury vial), explosive degradation products (ammonium) and other surprises like that. Earth near from them could be contaminated too.
I suggest you do not linger near from them. Perhaps you can arrange a meeting with a university chemical lab and know more about the set, including safe disposal options.

#17 This Fancy Hotel Has A Shallow Tub With Two Sides. When The Button Is Pressed, One Side Lights Up With A Red Light And Hot Water For About 30 Seconds. Then The Other Side Lights Up With Blue Light And Cold Water And Shuts Off After The Same Amount Of Time
Answer: This is very common in Germany, we call it “Wechselbad”. You’re supposed to keep your feet in the warm water first and then quickly put them in the cold water (repeat a few times). This is supposed to help with circulation although I’m not sure if there’s actually scientific evidence for that.
We usually have these in spas and other wellness or health related facilities.
