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!

#2 Saw This In A Restroom Which Has Faucets And Drain Down Low And A Dryer

Answer: This setup prevents Muslims from having to lift our legs up dangerously high while trying to stick our feet in the sink one at a time. The alternative to that is we have to take a handful of water and pour it onto our feet below the sink causing the floor to get wet. Muslims also have to keep their feet clean before praying, which is obviously problematic in a bathroom where everyone pisses on the floor and walks with their shoes between the stalls and the sink, so you might see them trying to keep one shoe on while washing the other foot and then switching. It’s also why we take our shoes off before praying and use prayer rugs to avoid touching unclean things while praying.

#62 What Is This Stuff In The (Seawater) Canal Next To My House?

Answer: This happens a lot in seawater. You see it in the beach all the time as a thick brownish foam. Basically, as marine creatures and so on (especially algae) decompose after death their bodies break down into various components. One of the processes is called saponification and basically converts fats into soap (fun fact, the same thing can happen to un-preserved humans). This coats the sand, gravel, rocks etc and then it is stirred up into foam by the water and (usually) high winds. On the beach it’s usually a mix of these animal byproducts, sand and other contaminants, it’s likely similar here but with less sand. In a canal it is likely stirred up by the wake of watercraft.
