Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

This is lemmy. Everyone has a favourite rock.
Mine is cummingtonite
They're fucking minerals Marie
I thought I was weird after seeing that black stand-up on kill Tony saying he had some of his favorites in his pocket. My step mom and I went hiking and she found two really cool rocks, one was gray and has streaks of purple, the other one was dark but with orange streaks. They live on my dashboard.
Dashboard, as in car dashboard? Or is that also a name for furniture?
Car dashboard.
While it's a cute idea, that's really dangerous. If you're ever in an accident, those things will turn into bullets, endangering you and possibly others. Even just a hard brake could make you lose an eye. I'd store them safely at home instead :)
Are you saying I (a huge human) would accelerate faster than>1lbs. rocks?
Not sure I understand the question. You're in a seatbelt, while the rocks are able to move freely throughout the interior of the car. They'll fly throughout the interior in the event of a crash. Even worse, if they are between you and the airbag when it's deploying, they'll be embedded into your skull.
I'm not making this up, you can find the same advice everywhere. It's very dangerous for you and other passengers.
I'm asking why you think rocks that are in front of me would be a risk.
Because, again, they will turn into projectiles during a crash. Do you think they'll just magically stay in their place? They'll fly around and inflict damage upon passengers, possibly also people outside the car. Please, just look it up if you don't believe me. It's very common safety advice.
The rocks are in the same frame of references the passengers. The only difference is they're not seat belted in so there is room for some small differences in acceleration.
If your car is doing 50 the rocks are doing 50 and then do have a fair amount of inertia compared to the outside world, but everything in the car has that same inertia. That two-ton automobile is the actual danger.
Absolute worst case those rocks aren't seeing any more than a couple of G, let's say you max out at around 3G which would be a little bit intense for car related escapades. The rock hitting you in the backseat would be like maybe it falling a dozen feet and landing on you absolute worst case.
Now, if you didn't have a windscreen, and you hit a stone wall that stopped you immediately The rocks would have a 50 mph variance to the wall. But, honestly, 50 mph on a rock is not really significant. Baseball pitchers double that.
You could try to argue that hitting another oncoming car would give them a 100 mph variance. But at that point the rocks aren't the problem the hundred mile an hour variance between the two multi-ton cars is more than enough.
The old wise tale that putting things on your dash turn them into dangerous high speed projectiles is false.
I think if you were looking for a solid argument of them being a bad idea, they will easily roll off your dash, get under your feet and would have a much better chance of interfering with your pedals.
In a crash, the car, you and anything else are all separate objects. Crash designers attempt to couple you to the car via your seatbelt and airbag. Rocks are free-floating.
When you crash, the car experiences a sudden deceleration. You're moving forward and the rocks are moving forward. The rocks will move forward until they hit the windshield and then they will bounce. They will also receive some of the energy experienced by the car's deceleration - which is MASSIVE relative to the mass of a rock.
Depending on the size of the rocks and the speed of the crash, those rocks very well may become bullets. Especially due to their high velocity and potentially small surface area.
I feel like some person genuinely attempting to look out for the safety of someone else and being lambasted for it is wild. Follow the advice if you wish but it's not like this is uncharted territory. Automotive engineers have been mapping crash dynamics for literal decades...
Thank you for being a voice of reason, felt like I was going crazy.
Why don't you get a couple rocks thrown at your face with 50mph and get back to me?
Bro, I am so not trying to sound argumentative. But please think about the plausibility of that happening. Like I seriously begging you! Even in this weird universe where smaller than a fist sized rocks could cause harm to another object while they are in a semi equal inertial state.
Even then, the windshield(which is sloped downward) would deflect said rocks into a downward direction.
So I'm asking you one more time, what is the danger of having cool rocks on my dashboard‽
My god you're dense. Fine, do whatever you want, I don't care.
Not hearing a plausible situation where things in front of me and passengers are in trouble...
I have to imagine that in any scenario where the rocks would be dangerous would also mean that you are fucked anyway.
No. People have literally lost their eyesight due to objects placed on their dashboards being smashed into their faces by the airbags. Had they not had shit on their dashboard, they would have been fine.
Please expand on this line of thinking. How are airbags going to accelerate objects beyond their reach?
Hematite is hella tight.
I had a different one in mind.
You just know the dude that named this had to be laughing to himself when submitting anything official.
I can't pick a favorite.
They're all neat.
