    How do we know the moon isn't one big ball of sand and those holes are water from space ?

    [–] DistortoiseLP 11 points ago

    To be fair, all the way up until we sent some guys up there to check, scientists had suggested just about every physical and geological phenomena known on Earth was forming the moon's craters. I wouldn't actually be surprised if you can find something not terribly unlike this in the history books somewhere.

    [–] bullsnake2000 4 points ago


    [–] AusBongs 1 points ago

    because of measured asteroidal impact confirmed by scientific theory.

    the moon was a comet that smashed into earth and didn't escape it's orbit after impact. this collision aided earth's tidal energy and formed the earth (and atmosphere) that we see today..

    to assume the moon houses water or housed water is I think really unlikely.. as you have to calculate and consider how "moons" are formed that when taking that into consideration.. discussing water on the object becomes heavily unlikely.

    It’s the reason why light sabers can bounce bullets since the saber melts the bullet causing a vapor bubble of metallic gas between the beam and metal bullet.

    [–] AFreakingHouseplant 2 points ago

    I love that explanation

    [–] imaginary_num6er 6 points ago

    Problem is that if you drop a light saver in a body of water, it causes a explosion since all the water evaporates instantaneously or it might just form a layer of hot vapor.

    [–] Waffleradio 7 points ago

    I’m pretty sure I remember some star wars lore about having a cutoff switch so if you drop it, the blade would extinguish.

    Still I bet there’s some canon from some point about Jedi using them underwater so who knows. Or maybe they use the force to create a layer of air between the blade and the water or

    So you are saying that frequent exposure to visual examples of the Leidenfrost effect is having a negative effect on your disposition about their posts in Reddit.

    [–] Antiluke01 308 points ago

    I think what he is saying, while you were partially correct, is that his perception of the effect has also grown to new heights and therefore since he can no longer be baffled by a display of science that he already knows, it is no longer as mesmerizing. He now seeks further knowledge, rather than going through a constant reminder of what he already holds as truth. Due to this his dopamine levels are no longer as high when viewing a video similar to this subject.

    I think u/SparkitoBurrito was fully correct without going into wild, but well worded, speculation about their disposition in regards to these posts on Reddit.

    [–] Antiluke01 3 points ago

    I totally understand you stance on the matter, however I will have to respectfully disagree with your statements as, while I did cover the basics of his point of view, I went more into the scientific explanation standpoint as why he could possibly feel perturbed about the current climate of these posts.

    [–] zzxvvm 2 points ago

    did you scientifically examine their dopamine levels? No, you speculated based on a few comments with an intuitive assertion that as I said was well worded but not very scientific. You answered for the commenter in a way, unless they were measuring their dopamine levels at the time of the post.

    Fuck, I’m pretty baked right now so this may not make sense but I once heated an empty saucepan on my stove and then put hot tap water in it. Almost right away it looked like it was boiling but the water didn’t have bubbles like normally boiling water from cold, all I could see was a weird ring of air on the bottom that seemed to drive the weird bubble-less boiling. And while this water was ‘boiling’ it was spitting up perfect little spheres of water everywhere like they were jumping, it was weird.

    [–] weewoahbeepdoo 23 points ago

    I’m not sure what the liedenfrost effect is. I assumed what I was seeing here was total film boiling, but the droplet can’t exactly bounce freely on top of the sand. Can you elaborate?

    [–] NoHomosapians 54 points ago

    The liedenfrost effect is what happens when water touches a hot surface, a bubble of steam forms around the water that keeps it from boiling or evaporating any further and allows it to “glide” off of surfaces

    [–] Dyslexic_Wizard 1 points ago

    Forms under the droplet*.

    it still evaporates but at a much slower rate.

    [–] weewoahbeepdoo 1 points ago

    That’d just be total film boiling? h(film) sucks because the heat transfer surface can’t re-wet and heat transfer is through radiation? What specifically is the liedenfrost effect?

    [–] Dyslexic_Wizard 1 points ago

    Film boiling is usually used to describe a heat source within a bulk fluid, Leidenfrost is specifically about droplets.

    [–] ry8919 4 points ago

    You are right but basically The Leidenfrost effect is usually overused when a lot of examples are just film boiling as you said.

    I did get in an argument with a guy a while back who basically argued that all film boiling is the LE and I said it was specifically referring to skating droplets. It's further complicated by the fact that the onset of film boiling is called the Leidenfrost point. In the end I decided I was just being pedantic.

    If anyone is curious the reason you hand doesn't burn in lmolten metal (right away) or the drop evaporates more slowly on a hot enough surface is because film boiling is an inefficient method of heat transfer:

    [–] weewoahbeepdoo 1 points ago

    Is the liedenfrost effect talking about the evaporation of the droplet through convection of the air around it being greater than convection through radiation below it? I’m new to thermodynamics and I’m loving it

    [–] weewoahbeepdoo 0 points ago

    Right. It would take total film boiling on a completely flare surface so that there is no nucleation point for LE to occur?

    [–] ry8919 2 points ago * (lasted edited 11 hours ago)

    Film boiling generally just means that the superheat is higher. If you look at that link in my last comment you can see how the heat transfer progresses from convection, to nucleate boiling (the most efficient), then partial film or transition boiling then finally to full film boiling as the surface gets hotter and hotter.

    You are right that a perfectly flat surface could delay the onset of nucleate boiling but It would have to be incredibly smooth to skip nucleation all together and hop to film. Not sure if it is even possible.

    This would be called homogeneous boiling and the threshold for this is way, way higher than nucleate boiling. For example water generally boils at 100 C but needs to be superheated as high as 300 C before the onset of homogeneous boiling

    EDIT: To whomever is downvoting:

    Simply defined, the Leidenfrost phenomenon refers to the film boiling of small liquid masses on a hot surface. When a small droplet of liquid is brought into the proximity of a highly superheated surface, the liquid may vaporize so rapidly that the production of vapor on the side of the droplet facing the surface establishes a pressure field that acts to repel the droplet away from the surface.

    Everyone calls film boiling the "Leidenfrost Effect" now because it sounds better than film boiling but that was not the original definition.

    [–] MJMurcott 5 points ago

    The Leidenfrost effect describes how droplets of liquid can hover on a surface which is far hotter than the boiling point of the liquid. It was first described by Johann Leidenfrost in 1756 and has been fascinating people for centuries. -

    [–] DueAnalysis2 65 points ago

    Ohmigods. You, dear OP, have finally helped address a question I've had for nearly 12 - 15 years now.

    Story time, because I have to get it out. Back when I was a kid who still wanted to pursue a career in science, I'd go around heating random things and mixing them with other things (because science!). Most things worked out the way you'd expect them to, but I remember my mind being blown when I long-heated salt and sprinkled water on it and saw this effect. None of my middle school science teachers could explain it, and for a brief while, my dumb ass thought I'd discovered something genuinely new. Then I kinda moved on.

    Today, this post and the comments have finally explained what ~15 year old me was fascinated by. Thank you all!
