For example, I’m incredibly confused about how you’re supposedly to measure liquid laundry detergent with the cap. At least the kind that I have sits on it’s side, so if you measure it with the cap it just leaks everywhere and makes a mess.
Or at my parents house they have a bag of captain crunch berries that has a new design, where instead of zipping along the top of the bag like normal, it has a zipper in the front slightly beneath the top. That way when you poor it you can’t see what you’re doing cuz the bag is in the way. Like what the heck who’s idea was that?
Water has both adhesive and cohesive properties, and this bullshit is one of the results. I hate it so much. Basically the bit of wwater in contact with the surface of the spout likes to stick to that spot; and the above that likes to stick to the water stuck to the surface and so on, making it kinda roll along angled surfaces even when it seems like gravity should be yanking it right off.
And they absolutely could shape the spout in a way that stops this - they just choose not to.
Never heard of the oil coating trick @DontRedditMyLemmy mentioned, but it makes sense - oil is hydrophobic, so that could eliminate the adhesion part of the equation; and without that moving the stream initially, its cohesion won’t be an issue either.
Or do what they do in chemistry which is to take a rod (or in the kitchen anything like a dinner knife or handle) and place it against the spout and let the liquid then run down the rod.
