BB packing problem on a cylinder (& the water paraboloid) 

Thanks. There's more about that jig on my second channel. Link is on the footnote. This could be amazing stuff, given the right equipment.

If you do this same thing with a more viscus fluid like corn syrup you should be able to reverse the rotation and bring the dispersal back to it's original state

Corn syrup is an interesting idea... Ha! As for putting the cereal back in the box, I'm afraid entropy is always increasing. But at least we can reverse our footage!

NightHawkInLight You can also just fill a watetbottle half way and spin it on the table.

NightHawkInLight Centrifugal force is fake btw.

Techminer where

i have seen something like this in other videos.... very strange

What

Looks like a bunch of red Zuma frogs

I’ve seen these split second frames in most of his vids. Not sure what’s up with that

I found exact center of the acrylic box by connecting the diagonals underneath. I put a pin-prick mark there, which I could still see from the top side. I spun the wheel to find the exact center point, and then I just lined those two points up ;)

The surplus just ends up on its floor. I found that I got better results with the reduced amount. They need room to space out a bit before settling.

Ok: we could do this in a barrel, so that you can't see the spinning. We then orient the cube so that it sits on just one corner/vertex. The liquid would go to the four corners! Viral video, here we come!

Yes, but it's still hard to get the little drop of dye back inside the bottle.

Science???????????

pocket83 just pour the water with the ink in Then boil the water

pocket83 probably the best comment response I’ve read in a long time.

Thanks. It's hard to do. It takes discipline to stay motivated! I always have another one in the works, though.

RiskyStrats ?

It doesn't work as well. They just spill back on to the "floor." It seems to work best with a little bit of room for them to space out.

Thanks! Great tip. I was unaware.

It's just a grip, just like the one that would come on your laptop or (Sometimes) your your TV remote

But it already is smooth. I think the choppiness is the unavoidable result of extending a 12" head to 40". A different machine/motor would be in order, if we were to continue chasing better results.

harry p0tter123 what the heck was up with that?

Ummm, the floor! I found that it worked best when they had room to space themselves out.

Nahh, not really. Inches are actually larger than centimeters, but that was just a jab at the Metric crowd. I never expected them to become so enraged over a joke. I had to delete all of the hostile comment strings.

Aww I missed the argument? I do love a good Imperial vs Metric fight lol.

No, that is factually incorrect.

I must disagree with you sir. I think we should agree in disagree. cm > inch

One inch = 2.54 cm. You are disagreeing with accepted convention.

cm > inch == cm bigger as a concept than inch, numerics do not apply in this discussion. I’m being threatened, running low on arguments 🤫

You don't need to argue with him, you know he's wrong and he should too but I'm sure he'll come to accept that

I don't understand what you are talking about. If you have a specific grievance, cite a specific time/example.

I wish I knew. It gets creepy; if you buy something at Wal*mart using a debit card, you might see RU-vid ads for that thing the next day.

Hey!

Yeah. I was poking fun at those of you who are so serious about it. I can't even mention 64ths without some _Systeme International_ Nazi demanding that I admit the inferiority of Imperial. Relax.

Nope, those are just the rubber feet.

pocket83 Oooooh, yes indeed, my bad!

Not in this case. Ideally, I would use marbles. And make it gear-driven, with a big, medieval looking hand crank!

Finally, somebody brought this up! Ok, I was a bit confused on the prototype, because I was _sure_ that I would have to consider the spacing in that way, and possibly modify the ID, or at least experiment with different tubes. At first, I just thought that I had stumbled upon a happy coincidence, but it turns out that it's far more forgiving than you might expect, because of two things, so far as I can tell: 1)the relatively large number of BBs that comprise the circumference, which can distribute a minor discrepancy over a large area, and 2)the mass of the rows on top, which help to implement that distribution, by determining the parameters of the crystallization (at the bottom) for all of the subsequent rows. Cool, huh? I hope I said all of that right.

That's an excellent point and could be shown thusly: Use transparent material for the cylinder and, turn (as on a lathe) the ID such that it accommodates slightly less than an integer number of BBs thus maximizing the gap. The gap should be more obvious.

Jellybeans.

Yes.

Yeah. I have to keep the physics statements to absolute bare bones, lest we risk angering Captain semantics and his un-merry band of self-designated experts. I wish people would learn to value concept and content over nomenclature, but so goes the struggle of trying to chisel out one's own identity; we tend to grasp whatever little power we have. Terra firma! I can know this! It feels good to have something secure in a transitory world, does it not? Even if it's only the labels for various types of motion. Oddly enough, despite our best efforts to designate movements as something non-arbitrary, there is only heat and the absence of it. Absolute zero, or movement. Everything else beyond that is only a man-made delineation: the finding of pattern where it perhaps does not exist.

homosapienssapiens19 Centrifugal force is actually fake, when in a spinning motion it requires gravity to accelerate it and cause inertia. That inertia isn’t actually directly outward but the force of the balls want to go straight forward but just get pulled inward. It’s not centrifugal force, but it’s just inertia.

[TVA] 1815 Delta III You have 0 clue about what you are talking about. Sounds like you just typed that with your feet after reading a highschool text book. "Fake", really? That's the word you're gonna use? Ever heard of "fictitious forces"? Damn right it's also called as inertial force. Talk about a rotating frame of reference. Whether you approach a problem with it or not, you're gonna end up getting the same results.

Please keep the conversation nice. I've had to remove dozens of hate-filled threads on the subject already, and I really don't like doing that. Seriously: do any of you remember your physics teachers screaming at you? It's hard stuff, so try to stay calm and understanding.

pocket83 Oh it's just my habit here and my natural tone! I'm quite sarcastic! My best physics teacher's not only shouted but sweared at us and whacked our shoulders with a rubber ruler if we do silly mistakes; not with hate but with humor. We used to joke around and insult each other so much. One bad thing about the internet is you can't see facial expressions and the tone of your voice. Miss the old days,... Oh well, this is your channel so it's your rules.

Irrelevant.

on time

Hentai Senpai you're making me cry

CONGRATULATIONS You are first!

Awesome what did I win lol?

NOTHING! You have to yell "FIRST," or else it's void, loser.

Wrong, sir! Wrong! Under section 37B of the contract signed by him, it states quite clearly that all offers shall become null and void if - and you can read it for yourself in this photostatic copy - "I, the undersigned, shall forfeit all rights, privileges, and licenses herein and herein contained," et cetera, et cetera... "Fax mentis, incendium gloria cultum," et cetera, et cetera... Memo bis punitor delicatum! It's all there! Black and white, clear as crystal! You didn't say "First!"! You numbered "woot"'s, which now have to be washed and sterilized, so you get... NOTHING!!! You lose! GOOD DAY, SIR!
