If you’ve ever found an object you couldn’t identify, you know how hard it is to try to figure out its purpose. You may ask your friends, your relatives, or your co-workers, but chances are if you’ve never seen it before, neither have they. So this is when strangers on the internet come to the rescue. After randomly finding intriguing objects, the following people reached out to the internet to find some answers. Here are some of the most interesting objects people have found and their purpose – according to people who actually know.

It’s used to test quality assurance mechanisms.
It turns out most production lines use objects such as this metal Hershey’s Kiss to check quality assurance mechanisms in order to test their ability to detect and remove any foreign matter in their machinery. This specific Kiss-shaped metal object could have been designed to be detected by visual inspection or by magnets – and slipped by both.
“What is this white globe on top of that building?”
It’s a weather radar.

“What is this ring my Uber driver would randomly click?”
It’s a prayer counter.
In some religions, prayers have to be repeated several times a day.
