World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Put your money where your mouth is. Take an old gasoline can and fill it with cooking oil then feed it to your family until it's empty. Record the results. You won't though.
No shit.
My question was an honest scaling law question. Of course this is bad. Which is what I said.
My question is how bad, which is a legitimate question, and is not in any way saying these are defensible actions. They are not.
If you fill a thimble with diesel, drain it, and then fill it with water, that's gonna be super gross
the diesel will probably form a thin layer on the thimble which is then diluted with a thimble full of water. Super gross. But by the time you get to a fuel can, the thin layer of diesel on the can is now diluted by a can of water. Because surface area scale like length squared but volume like length cubed, this is a better situation (for a given amount of water). Now when this is scaled up further, the diesel gets increasingly diluted. This is the root of my question, it's not saying that we should accept this or that it's good, I'm just curious.
If a cup has a few drops of water after you pour it out,
Say a drop is 0.05ml (20drop/mL is rule of thumb for chemistry). Say your glass cup holds 16oz (mine does), that's 473mL.
(4*0.05mL / 473mL) *100 = 0.04228% of the original concentration. Now scale that volume up. That ratio is going to be much smaller, since you're right about volume vs surface area.
5ppb is the cutoff for benzene in stunning water in Oregon apparently. EPA says 5ug/L.
5ppb is apparently 0.0000005%. That's about 84,000x higher than the cutoff for that one potential contaminant.
Given how small the minimum acceptable level is for many chemicals in gasoline or fuel... Yeah I bet it would increase cancer rates in a statistically significant way.
So 84,000 for a glass assuming 100% of the fluid is benzene (unless I misunderstood your calculation). Benzene concentration is about 1% of gasoline, and a tanker is about 20,000L, or ~40,000x more than a cup. Cube root of 40,000 is about 34 (cube root for the surface to volume factor). 34*100 is 3400, which is about 25x off from the 84,000 reduction required to be "safe." So it's roughly 25x worse than the Oregon cutoff (but seemingly within EPA limits, which appears to be ~1000x less stringent [!!!]). Unless I made some errors or misunderstood.
In any event I'll try to source my cooking oil from uncontaminated trucks!
(As an aside, thanks for taking my question seriously and putting thought into an answer, unlike some of the other more "colorful" responses!)
Test it out bro. Since you believe the impact of putting gasoline in food is so contentious. It's funny how you still deflect by implying it was "a thimbleful" when you have no idea how much it was or how dangerous it is.
B-b-b-but you're just asking the questions right?
...scaling laws. They are best illustrated with different sized items. Like a thimble, a coffee cup, or an oil tanker, all representing volumes of different orders of magnitude.
