| Why does water from a faucet "wobble" when the stream is weak and shortened? Posted: 08 Jan 2020 07:58 PM PST I apologize for the mediocre phrasing, but I cannot seem to think of a better way to describe this. The attached video demonstrates this effect rather nicely. To be more specific, why does the stream of water begin to ripple when I intercept it with my finger? Moreover, why does the amplitude of the rippling increase as the the distance between the facet and my finger decreases? Thank you in advance for any insights offered!

| Posted: 09 Jan 2020 01:49 AM PST I love spicy food and have done ever since I tried it. By spicy I mean HOT, like chilli peppers (we say spicy in England, I don't mean to state the obvious I'm just not sure if that's a global term and I've assumed too much before). I love a vast array of spicy foods from all around the world. I was just wondering if there was some evolutionary basis as to why spicy food managed to become some widely consumed historically. Though there seem to It way well be that we just like a tingly mouth, the simple things in life. [link] [comments]  |
| Why does nicotine make me feel like I can concentrate better? Posted: 09 Jan 2020 02:52 AM PST Basically wondering why I have better concentration when I have nicotine in my system (often added to caffeine as well). Could it be due to ADHD? I know I was diagnosed at a young age with it. Thanks in advance! [link] [comments]  |

| Is it possible to turn alloys back into their base metals? Posted: 08 Jan 2020 07:26 PM PST As title above. Is it possible to turn alloys back into their base metals? Why or why not? Thank you for any answer. [link] [comments]  |
| Does the shape or our brains determine or at least influence the way we think? Posted: 08 Jan 2020 09:43 PM PST So we all look human, however we all have differences in the way we look. I wonder whether our brains grow into (slightly) unique shapes and structures that allow some connections to be made more efficiently and maintained more easily and those pathways are what determine our personality and the way we think? Basically what I want to know is if our brains are built from our genetics, then are we each predisposed to certain ways of thinking as a result of the structures of our unique brains?

| How do underwater plants preform photosynthesis if the process requires carbon dioxide? Posted: 08 Jan 2020 08:33 PM PST Do underwater plants have to ability to get energy some other way or how can they obtain carbon dioxide since there isn't any underwater? [link] [comments]  |
| How extreme is the pressure at the bottom of Ganymede's global ocean? Posted: 08 Jan 2020 11:13 AM PST I'm fascinated by Jupiter's (and the solar system's) largest moon Ganymede. A global ocean underneath the ice almost certainly exists and some models suggest it is 800 km deep!!! That puts the Mariana Trench to shame. My question is what would the pressure be at the bottom of such an ocean after taking into account the lower gravity? What properties would the water have under such conditions? [link] [comments]  |
| Did humans prevent an ice age from happening? Posted: 08 Jan 2020 08:43 AM PST Looking around I found out that ice age happens in cycles and we were due for another one for a while. Temperatures were also trending down until greenhouse gases warmed the planet back up. And if we cancelled this ice age from happening, what will happen when the ice age ends and the planet heats up even more? [link] [comments]  |
| Why is Oxygen an Electron Acceptor since it already has a charge of -2 (2 extra electrons)? Posted: 08 Jan 2020 11:31 AM PST This seems like a really stupid question, so I'm sure I'm misunderstanding something basic here. But why would an electronegative anion like Oxygen, and others, like Fluorine, be oxidating agents? So if they oxidate another species, they take their electrons. Shouldn't it be the opposite, that they donate their electrons since they already have a surplus? [link] [comments]  |
| Posted: 08 Jan 2020 05:12 AM PST Is a person's gait determined by the parent's or are other factors capable of affecting it too. [link] [comments]  |
