  • Drop your most "wtf that's not how the world works" from movies/tv shows.

  • I hate to say it because so much of this show was actually really excellent and accurate but in the Chernobyl miniseries they totally did the "radiation is contagious" thing and it is just not true.

    Things and people that are irradiated/hit by radiation in a situation like a reactor failure or contact with radioactive waste do not become radioactive. They can have radioactive particles on their clothing/skin or inside their body if they have ingested/inhaled radioactive material, but they are not emitting radiation themselves. Furthermore, a thin sheet of paper or cloth will stop the kind of radioactivity that would be emitted by such material, if it is on the outside of a person's body.

    Anyways the point is that the woman whose husband was dying of radiation poisoning and then she went in and spent time with him did not lose her baby because she spent time with him. That's just not how it works.

    Lots of environmental contamination-related stuff in movies is inaccurate but that one is the most recent I can think of.

  • In your experience, what is Halloween all about?

    Jump

  • Letting kids (and kids at heart) go wild with their imagination and dress up.

    Meeting/seeing neighbors.

    Eating candy.

    I feel really sad for all the folks on lemmy having a bad/frustrating Halloween. I think it doesn't have to be that way, but it does definitely take neighborhood-level effort. We're really lucky to live in a big Halloween neighborhood in a walkable area. We saw all our favorite neighbors and met some new ones, and enjoyed all the creative decorations and costumes we saw while we were out.

    But the best part of the night is always getting to see people light up when you recognize their costume. Every time I see a kid dressed as Batman and go "whoa there's Batman!" or compliment a princess on their beautiful dress, you can just see them stand up straighter or strike a pose and it's awesome to see everyone dressing up and enjoying themselves. I probably saw a dozen Marios tonight from age 2 to age 20 and every single one of them was over the moon when I complimented their costume.

  • I think it's more like sunlight energy + adhesion energy - cohesion energy, because the capillary action is also helping to lift the water but generally yes the energy is coming from a combination of the chemical forces in the water and the pressure gradient from the sunlight/heat.

  • Generally, yes, but in the case of trees there is also negative pressure (vacuum) exerted from transpiration when water leaves the top of the tree and "pulls" other water up behind it.

  • What you are describing is not osmosis, it is capillary action. Capillary action is caused by the forces between the water molecules and the molecules of the tube overcoming the force of gravity. You can read more here: https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_Chemistry_Textbook_Maps/Supplemental_Modules_(Physical_and_Theoretical_Chemistry)/Physical_Properties_of_Matter/States_of_Matter/Properties_of_Liquids/Capillary_Action

    Briefly, the water molecules are attracted to the molecules of the tube by adhesive force. The liquid molecules are also attracted to each other by cohesive force. The interplay of these forces causes capillary action.

    However, it seems that tree sap moves by more than just capillary action. If you scroll down part way in this book they talk about it a bit: https://pressbooks.online.ucf.edu/phy2053bc/chapter/cohesion-and-adhesion-in-liquids-surface-tension-and-capillary-action/

  • Yep, it's me

    Jump

  • Kids love this shit as long as you keep it at the ELI5 level and stop when they are done and lose interest. My kid will throw around words like "microorganism" and "bioaccumulation" because I actually explain biology concepts when he asks. The other day he had a question about atmospheric composition and he was absorbed for about 5-10 minutes, complete with looking at molecular diagrams, and then he was done and went off to make his Lego people fight each other with flamethrowers.

    If you have knowledge, share it with kids and let them see you enjoying science. They absorb more than you might think.

  • Growing up with ADHD starter pack

    Jump

  • Yeah. ADHD mom here. Had a good cry tonight about my kid and all his challenges.

    I try to keep on the happy face when he's around but parenting a kid with severe ADHD is really hard sometimes.

  • what's your first otc medicament for a headache?

    Jump

  • Acetaminophen (Tylenol) if I can't get it under control without meds but I agree with the other posters about trying to figure out the root cause! For me, the main causes of headaches used to be hormones from the pill until I switched to a different form of birth control (IUD). Nowadays my headaches are mostly dry eye or allergy related so I keep eye drops on hand and take allergy meds and I'm down to headaches once every week or two. Staying hydrated and taking fish oil supplements has also helped my dry eyes.

  • Mail addressed to Mr. and Mrs. (husbands name)

    Jump

  • Yep I get mad about this as well. Esp since my title isn't Mrs. it's Dr.

    We always joke they should have addressed it Dr and Mr [my first name last name] but of course the real answer is they should just call people by their actual names and titles and not guess.

  • Starfish memory

    Jump

  • Yeah this is what happens with our kid (who, admittedly, has ADHD so maybe he's a bit unusual). The first day or week after a cool experience he's pretty meh about it and won't volunteer much in the way of thoughts or feelings and then suddenly he'll realize it was real again and all of a sudden he won't shut up about how cool it was! Then eventually he settles down into a steady pattern of "hey remember when we did X thing wasn't that so cool we should do it again" which is my favorite phase because that's how I know what he really likes that stuck with him. : )

  • You had me there at the first half, not gonna lie. 🤣

  • How many pieces of toilet paper do you use to wipe after peeing?

    Jump

  • Not OP, but we have a bidet and a basket of cut up t-shirt cloths next to the toilet that are single-use and then go in the wash every week. I wouldn't personally reuse washcloths for wiping out of fear of UTIs, but I'm extra paranoid.

  • Small 'micromobility' vehicles gain traction amid rising car prices

    Jump

  • We have a Lectric XP 3.0 that is just... Okay. The features are great, especially the large cargo space, the fact that it folds so you can store it in a small shed, and the odometer/display is good. As far as actual bicycle build quality it's not the best, it's pretty rattly and we've only had it a year but it's already developed an annoying brake alignment issue that I'll need to find time to fix soon. That said, you can't beat the price (<$1,000 if you get it on sale, and they have pretty much constant sales) and it does have the ability to carry a passenger.

    I'd say the Lectric is a good bike to get if you are comfortable making your own bike repairs and want something cheap. We got the cargo package and the comfort seat free with our Lectric and we use them both and like them. It's a good little bike and it gets the job done, even if it's not super refined.

    For our main cargo bike we have a Flyer folding cargo that's fantastic except that the paint chips easily. But other than that one issue I'm 100% sold on this bike. It folds, it tows, it carries either a kid or a large amount of cargo, and the battery range is really good for the price. The battery assist is really peppy, which I love, and it's got a thumb throttle rather than a twist throttle which I personally think works better on an ebike where you're also keeping your hand on the hand brakes all the time and don't want to take your hand off to grab a twist throttle. It has a lot of other "extra" type features that are nice like a brake light, beefy kickstand, a carry handle on the battery, and a chain guard. Overall the design of the Flyer bike is really nice and it's solidly built. No rattling or brake alignment issues like the Lectric.

  • [QUESTION] What are you favorite preps/hacks/tricks/recipes involving a freezer?

    Jump

  • I freeze soups, curries, and sauces in those plastic deli containers. If you're freezing something that goes with rice, freeze a container with a portion of rice too.

    Then just take the frozen container(s) and put it in your lunchbox- voila, ice pack plus food.

    You can freeze nuts to make them last longer. Also bread. Also hot peppers like serranos. If you have lemons that are going to go bad before you use them, juice them and freeze the juice.

    Some leaves and spices that you get in large quantities, like curry leaves or kaffir lime leaves or lemongrass you can freeze the extras in bags until you need them again.

  • Small 'micromobility' vehicles gain traction amid rising car prices

    Jump

  • Ebikes, especially e cargo bikes, are the absolute bomb.

    I can carry my 6 year old on the back while towing 60 lbs of groceries in a trailer and keep a steady 15mph even on hills without breaking a sweat. For my family, e cargo bikes are what will finally make the dream of car replacement a reality.

    These other weird scooters seem cool too, maybe if you don't have kids and don't often carry cargo then something more sleek and portable is better.

  • What’s your “I can’t believe other people don’t do this” hack?

    Jump

  • Agreed. We have kept wearing masks in specific places (public transit, crowded events, airplanes) and it really does make a difference. I never get sick from airplane trips any more, which used to be a fairly regular occurrence.

    I will say, I was never able to figure out how to stop a properly fitted mask from giving me a terrible headache after 8 hours of use so I'm glad I work from home and don't need to make the choice of mask vs comfort at work.

  • To help you decide on your next daily driver

    Jump

  • Yep other EVs have this as well. The Hyundai IONIQ has great front sightlines for an SUV IIRC.

    Still a car, but I admit EVs are much less hateable in a city for multiple reasons. No stinky tailpipe, no roaring engine noise, and generally better sightlines and safety features.

    I think my ideal city would be mostly bikes and ebikes, with those vehicles that can't be replaced by bikes being EVs.

  • Radio Flyer launches new 20 MPH utility electric bike

    Jump

  • I have the flyer folding cargo and absolutely love it. It's such a good set of features for a cargo bike at that price point.

    The only complaint I have is the paint, which for some reason is super brittle and chips easily. I wish they would just use regular bike paint. But I put up with having to patch it regularly because the rest of the bike is such good quality otherwise and, c'mon, it cost $1800!
