From yard sales to the attics of our parent's homes, we have all probably come across weird objects that don’t seem to have any discernible purpose. Like anthropologists studying the site of an ancient city, we had to try and piece together contextual clues. But these days, through the magic of the internet, we can simply ask hundreds of thousands of people to help. 

The “What is it?” online community is dedicated to helping people understand what obscure object they are looking at. So get comfortable, make your best guesses in the comments, and be sure to upvote your favorite posts.

Found While Hiking, What Is This Thing?

Found While Hiking, What Is This Thing?

Answer: MCH (3-methlcyclohex-2-en1) bubble, MCH is a pheromone given off by female Douglas-fir bark beetles after laying their eggs that affects the behavior of other beetles by communicating to them that eggs have already been laid on this tree and signals to the other beetles to leave that tree alone. Basically they’re placed there by the Forestry Service to prevent infestations of bark beetles, if you see them, leave them alone

    Bored Panda got in touch with the moderators of the subreddit, and they were kind enough to answer some of our questions. “Firstly, we were curious to hear how the page even came into being. The subreddit was made 14 years ago by a different user that I have no contact with. He had abandoned it, and the sub had been dead for a while.”

    ADVERTISEMENT

    “About 5 years ago, I took over the subreddit using r/redditrequest, because I was interested in seeing what it was like moderating a subreddit. The sub was pretty small for a long time, until the beginning of this year when it began getting large amounts of new members,” they shared with Bored Panda.

    Naturally, we also wanted to hear their take on why the page suddenly grew in size. “I'm almost certain that the big boost in members is due to the Reddit API protests that happened earlier this year. During the protest, a lot of big subreddits went private, and I guess that caused the algorithm to start recommending small subreddits like mine.”

    We wanted to know what the mods thought was the main draw of the group. “I think that people are drawn to the subreddit because, for a lot of people, it's interesting to look at weird and unusual-looking objects and learn what they are. I have learned about a lot of things I would have never known about if it wasn't for this subreddit. As for me, I have never personally used the subreddit to identify an object.”

    “It's been fun watching the subreddit grow over the years, and seeing all kinds of interesting items be identified by the community.” Lastly, we were also curious if there were some items that simply went unidentified. “We have a whole flair dedicated to items that haven't been identified, but the majority of items do get identified eventually. There are lots of people who see the posts, so there's a pretty high chance that someone knows what the item is.”

    semi trucks pull a surprising amount of vacuum behind them. One time I was having severe engine problems due to a slipped timing belt / very little power. But it happened while driving from WA to lower Idaho and I HAD to get back due to in military and coming of a 5 off / staring a new work cycle. I ended up traveling for several hundred miles with a trucker, talking to him on the CB. If I tailgated him the suction from his truck added enough pull I could keep up to speed. if I pulled out in the other lane my car immediately started slowing down. It was interesting / kind of scary. I drove a few hundred miles so close all I could see was the back door of his trailer - him on the radio telling me if there was bend in the road or he was going to slow down. He got me to Idaho Falls and I limped across town to my rental and parked. Had to overhaul the engine before I could drive it again. I was still young/immortal. Kind of cringe to think about now.

    There is a somewhat hidden benefit as well. Uncertainty does often leave us feeling stressed. Some psychologists believe it's even the root of much suffering, albeit often buried behind multiple other stressors. So being able to resolve these little mysteries, one at a time, might be doing us all some good.

    So reading the original thread - that red thing is not the button. It is an indicator that the button has been tripped. The button is underneath. The two holes are for a pronged reset tool. I wondered why the panic button would be sticking out like that where it was likely to get accidentally bumped.

    Indeed, some research suggests that the old cliche of preferring the “devil you know versus the devil you don’t” has some basis in reality. Resolving a stressful situation, even if the resolution is negative, has been found to reduce stress levels relative to the stress the situation would cause in the first place.
