Is it a bird? Is it a plane?! Unfortunately, it most likely won’t be Superman. And, chances are, it’s not the Twister either. But it is something peculiar. It’s an unknown object (not from space, though!) that needs some help from the Internet to identify it.

Luckily, there is a subreddit for that. The What Is This Thing community is fortunately still going strong with more than 2.7 million members! It’s a place where you can post a picture of an item that you can’t for the life of you figure out what it is or where it came from. The Internet will most likely come to your aid, and the subreddit’s detectives will tell you what your strange object is.

This time, we’ve compiled a new selection of the best entries from the community for you to enjoy. So scroll away and let us know your favorites by upvoting them!

The osmoscope. It measures the intensity of odors using an exponential scale in powers of two. The process works by dilution of the odor by air. This tool was created around 1938, and works by diluting the odor in the air. The device is then inserted into a test tube, and holes in the side of the tube allow air to enter. A sliding jacket is then drawn up the osmoscope to progressively cover the tube and holes in order to create a more intense odor.

Direction finding (DF), or radio direction finding (RDF), is the use of radio waves to determine the direction to a radio wave source. The source may be a cooperating radio transmitter or may be an inadvertant source, a naturally-occurring radio source, or an illicit or enemy system. Radio direction finding differs from radar in that only the direction is determined by any one receiver; a radar system usually also gives a distance to the object of interest, as well as direction.

#80 Copper Coils In Every Closet In A 1920s House In Seattle. All Coils Are Wired Together Into A Central Line In The Attic

A quick translation indicates “Heat detector by air action”The one you shared a picture of looks in very good condition (better than the example they used for the catalog; might want to take it an antique dealer and see if it’s worth anything.
