The answers come to those who seek them. Especially on the subreddit 'What Is This Thing?'
This online community is home to 2.3 million members who are always ready to help people identify the mysterious objects they found.
The gig is simple: someone uploads a photo of whatever it is they want the name of, and the gang starts commenting under it, offering their input until, inevitably, a person shows up who knows exactly what it is.
However, even if you're not posting anything, scrolling through their solved cases feels like an interesting challenge, where you can test (and expand) your own knowledge. So we invite you to do just that!
