  • Okay so this reminds me of something that happened in a college chemistry class and I was wondering if someone here can offer an explanation.

    We were doing an experiment that first involved dissolving some copper into a solution, then chilling it to add another ingredient, then heating it on a hot plate. After doing all the other steps, I placed my beaker on the hot plate and turned around, then I heard a hissing sound. I turned back around just in time to see my beaker flying off the hot plate, off the counter, and smash on the floor.

    My best explanation for this is that since the hot plate was already hot, some condensation from the previous chill step had dripped down, flashed to steam, and propelled the beaker off the hot plate.














  • It depends on the design of the toilet, and how much water it dumps into the bowl at each flush. Some toilet designs have a tank with a higher capacity than the bowl, so if it gets clogged then it’ll overflow. Pro tip: know where your toilet’s shutoff valve is, it’s usually on the wall just under the tank. If it looks like the toilet is about to overflow, just turn that valve off and you can avoid the mess.




  • I don’t know, but it’s not a parking space. Because you don’t park there, and it’s not a destination. The photo above doesn’t look like a charging station, it looks like a business.

    More and more I keep seeing businesses plopping down chargers right outside the front door, and marking previously open parking spots as “EV parking only”, giving them special privileges even if they’re not charging. And if I try to park there? Suddenly I’m the asshole, as if I tried parking in a disabled spot.
