The key was also higher velocity. Dumping from a much steeper angle would have obtained more spinning. More Mercury also gave more energy because the layer was thicker, which had similar effect, but consider both effects simultaneously...

I could be completely wrong but I feel like that could put a lot of pressure on the glass.

[@korishan]

@@bwood6337 Only needs to be a pane of glass about 10" x 10" or so. And, being only tenths of a mm separated, would allow for the mercury to be present, but not enough mass to be a weigh issue. Now, that's not saying that the "mirror" will now be much easier to crack.

[@johnp893]

​@Squiggummer Figgammus Could he perhaps make a parabolic reflector by putting mercury in a bowl and spinning it at the correct speed? That'd be a pretty cool telescope if it works, but I'm not sure if spinning mercury in a bowl would give you a paraboloid or something else.

[@JesusisJesus]

As an extension of this idea he could do this between sheets of Perspex or plexiglass and have a bendable mirror, by sealing the edges with silicone, he could even set the two sheets into the bent shape at the time of siliconing it together. All of which has great potential as mirrors, telescope use, or even focusing several at a solar cell to multiply surface area. As for the bowl suggestion above, Mercury can be spun by applying electricity to it but I believe that also heats it up, which would lead to evaporation problems.

[@travisheck5979]

Cody, the mercury wasn't sliding. The friction was still rolling friction. Fluids are stationary at a boundary, and thus it was in fact rolling. Rolling friction increases with deformable objects, with liquid being the ultimate deformable object... So the rolling friction was like a flat tire times ten. But it wasn't kinetic friction like you say in the video. I believe static electricity plays a part too, look at the balls that hang around.

[@fredorpaul]

This is a really good description, also explains why high flow rates worked so much better. Less rolling friction (and static generation?) due to a more stable boundary layer.

[@LilJbm1]

Honestly I think it also has way more to do with how much heavier the mercury is than a coin, so it loses all its tangential kinetic energy to gravity pulling it towards the hole almost instantly. Friction is definitely a part of it, I just think gravity is really the bigger reason

[@somethingsinlife5600]

The "collisions" among mercury blobs is very interesting. It simulates all the stuff colliding near a black hole and producing those "jets".

[@ExperimentalFun]

I wonder how much the gyroscopic effect helps in keeping the coins spinning around longer then just the centrifugal force alone? It would be really interesting to see how long the mercury spins around with a near frictionless surface.

[@allesklarklaus147]

Experimental Fun The gyroscopic effect just keeps the coins upright and only if they are spinning (as in rolling down the funnel). And as long as the coin rolls it has less friction and the gyroscopic forces help it not fall onto its flat side and prevent it from rolling. But apart from that I wouldn't suggest any influence on it's "orbit" around the center hole

[@maxximumb]

The main force is conservation of angular momentum. The coins want to keep going straight, the funnel's shape curves the the coin's path. It's the same as the old spin a bucket of water over your head fast enough and you won't get wet.

[@allesklarklaus147]

Can't heat plastic enough as it would start to melt and any large basin would most likely cool way too quickly to keep completely heated.

[@worthingtonswands]

Molecules in the mercury experience fluid friction as they slide past each other, creating drag and sapping tangential velocity. A coin has only rolling resistance, and its solid round shape maintains inertia much better than a sheet of viscous mercury shearing in order to roll. The mercury might fare better if the surface of the coin funnel was coated in a ultrahydrophobic material conducive to smaller rolling beads of mercury, and if more tangential velocity was imparted to these beads to begin with.

The coin slowing down and going towards the center of the funnel is basically every single "perpetual motion machine" ever devised. I'm sure you can optimize a rig to have the drop off in speed happen over as long a period as possible, but there's no way to make the coin speed up and move back out towards the edge of the funnel. Such a simple demonstration of entropy.

[@youngkim5909]

You need more momentum on the mercury cody. pour the mercury from higher up so it has more potential energy being converted to kinetic as it exits the ramp into the funnel.

[@Klaevin]

But it would lose all that kinetic energy the moment it slams against the funnel and changes direction. Maybe if the ramp were longer, though...

[@xogmaster]

@@Klaevin YES ladies and gentlemen we need a bigger SLIDE! One that won't come in at a hard angle.

[@josephrissler9847]

I think in both funnels the mercury was losing energy when colliding with other surfaces. With the small funnel, the mercury bounced of the rim of the funnel, probably because it had more momentum than the coins the ramp was designed for. With the large funnel, Cody was using a straight ramp, rather than a curved one, and so hitting the funnel was a sudden change in velocity.

[@mickenoss]

Was thinking the same thing. If he put a few feet of tubing into that bottle and raised it up, he'd get a decent flow out the end of the tube - maybe enough for the mercury to do a couple circuits.

[@youngkim5909]

@@mickenoss Ur right, tubing would be even better, you could lay it parallel to the surface of the funnel so it doesn't lose any momentum as it his it and gently curve it upwards. That way he would also be able to calibrate the terminal speed of the mercury by just pouring it from a higher or lower height.

[@soeveth]

I think the issue is the the mercury is alot denser and not getting enough energy from your launch system. I would like to see you get a 10 foot pvc pipe and attach to a step ladder or something and pour it down that.

[@gertboltenmaizonave2421]

Exactly the comment I was looking for. I was actually thinking of something more compact to give horizontal speed to the liquid before it reaches the funnel, like a broad logarithmic ramp.

@@gertboltenmaizonave2421 I was thinking a step ladder just so he could easily change the height of the pipe easy to test the best height to speed ratio for the funnel.

[@Whargoul1942]

and play with the launch angle more. i felt like he'd of had better results with the first funnel if he used the ramp while holding it up and a different angle so when it hits the funnel the stream is more tangent. the mercury was just splashing against the rim falling straight down.

[@allesklarklaus147]

The mercury is very dense and hence heavy so it does indeed "get" a lot more energy when you drop it from a given height. I'd say with a big launch pipe it will just fly out the funnel straight away. One suggestion is using the launch pipe and a much steeper funnel

The reason the coins rotate for such a long time but the mercury falls so quickly is because the coins offer greatly different friction coefficients in the direction of roll compared to across it's direction of travel down the hole. No doubt a coin carefully placed at the top will simply sit there and not slide down at all due to friction, while a liquid has no significant friction keeping it up against the force of gravity.

I think the mercury acts more like how a ball would fall into it because a coin easily roll forwards and backward but not so much side to side and a ball can roll anyway which has the least resistance. I know it's not exactly like a ball because of sliding rather than rolling and internal friction with the mercury being liquid rather than solid. still very interesting.

I think the main issues that make coins work better (besides the obvious higher friction) are: 1. Because the coins are rolling, they have a higher center-of-mass, so the final spiral is tighter 2. Because the coins are rolling, they have more inertia.

[@kenanderson3954]

its not just that rolling friction has less loss of energy, it's also that wheels move well in one direction and very poorly in the direction perpendicular to that motion. This means it will roll around the funnel and not slide straght down into it (which the mercury is much more apt to do as it moves freely in all directions).

Hey Cody, i make carbon fiber race car parts for a living and use a mold release wax in paste form daily. We have a procedure for applying it that makes the wax build up in extremely thin layers without distorting the image quality of the mold (i wet sand the molds to a 3k grit before a 4 stage buff ending in a glaze polish that makes them a flawless mirror image), I can get the exact type/name of the wax we use if you're interested, you could apply the wax to the funnel and decrease the friction substantially which in theory would help the mercury rotate much easier. We apply the wax with a cotton applicator (same ones used for cars) in thin layers so minimal force is needed for removal with a micro fiber rag, let sit for 10 min and remove. You then let it sit for 1hr for the wax to fully cure and re-apply. Depending what we are doing we apply 8-12 times on our new molds and then just 1 time before every use after that. The bonus to the wax we use is it doesnt come off with heat (some of our resins cure at 400+deg F) and it takes several times of washing your hands to start removing it lol....

You see the same comments on videos dealing with casting or recovering lead. Everyone wants to be helpful and look smart. If you were wearing a full hazmat suit people would warn you not to trip or get too hot.

[@among-us-99999]

Be careful with that butter tho

[@osolomons]

I think it's also worth noting that although the coins have less friction in the direction they're rolling, they probably have more "sideways" friction, which I imagine plays a big part in this.

“Clearly the key here is more mercury,” Clearly the key anywhere is more mercury, Cody...😂

Another very Cody thing to do! EDIT: have you ever dropped your phone in the mercury?

[@theCodyReeder]

Yes and the charge port hasn't worked properly since.

Not sure you can drop a phone IN mercury, on it almost certainly, but the density of mercury would almost certainly make the phone float.

Hey Cody, the other day I was thinking about you and wondered if you ever get threatening emails or calls from people wanting you to create bombs for them or other dangerous things. You have such a brilliant mind that I bet a lot of people want to exploit.

Thank you for the disclaimer on mercury exposure, I'm sure it's highly appreciated. Good to know that you're well informed and knowledgable on how to reduce mercury poisoning, and it settles a lot of my worries for you.

[@bananaman5238]

[@themadlad5577]

Cody you forgot to edit the first time you mention the fountain. You explain it once at (6:59) and the again at(7:18) you start talking about it again (this time adding that you want to have jets that shoot the mercury in a horizontal velocity)

[@dannybeusse5836]

It's because he really wants to make a mercury fountain 😂😂

[@SpydersByte]

I thought he just took a second to mark the stop and then repeated himself and later forgot to edit it out but you can easily see the clip break right before his pause so that isn't the case, he must've just edited in 2 takes for some reason

[@maxkevin9508]

If you would put a layer of ice on the funnel, the mercury would melt the ice like an ice-skate and have way less friction. The experiment may work a bit better. I think you shuld try that.

[@TheFrontyer]

How would you make ice freeze on it though? The water would just fall down through it

[@maxkevin9508]

@@TheFrontyer You can spray the water on. the tiny droplets will stick like they do on windows. spray a layer, let it freez and repeat.

[@athaclanor]

Cody, you could reduce the friction of a liquid with the Leidenfrost effect, meaning it would have more of that spiral goodness before it falls right down. I don't know if that is safe to do with mercury but something else with less toxic gas might be good. I also don't know if you can heat the funnel enough for that without it breaking.

[@henage]

I was going to suggest this too. He mentioned enclosing it to keep the vapors in. The metal would probably also have to be over 360 celcius for the effect. Another comment mentioned milling the funnel out of dry ice, that actually might be more feasible for a one time video.

[@athaclanor]

@@henage Perhaps its possible to get dry ice to build up on the plastic funnel rather than to carve it out of a solid block, which seems difficult to make.

[@henage]

@@athaclanor I like this idea. Maybe using a metal funnel (plastic may become too brittle) with liquid nitrogen or poor mans liquid nitrogen (dry ice + alcohol) underneath and a pure CO2 atmosphere above.

[@-_MonsieurNashty_-]

Cody, I personally think that you could become a Chemistry Teacher with the amount of refining and other goofy and cool things that you do. Keep it going and think about the job!

[@BEEGfrog]

Cody,the biggest issue I observed was the relative lack of angular momentum of the mercury compared to the coins.The coin ramp had a high initial slope to maximise potential energy conversion then it shallowed out to convert the maximum amount of energy to angular velocity. Please build a mercury ramp so you can get a large volume of mergury in a single mass entering the funnel with a high angular velocity.

[@trus3683]

I thought it would spin a lot longer too

[@FrankLassowski]

Hm. What about machining a funnel out of dry ice and try the mercury again? Due to the Leidenfrost effect it should work pretty well.

[@henage]

Cool idea. It would be temporary and wouldn't work long term for a fountain. Also if it was a fountain the mercury would probably freeze after being circulated. But I would love to see a video of this.

[@PARALLELPEOPLEAKSHAYB]

I think Mercury is Cody's weakness

[@rml4474]

So what We can conclude from this, is that Mercury = Butter!

[@zeuzrad]

A coin lasts longer because it spins in one axis, a fluid will spin through the less resistance axis, that and add surface tension and the fluid will go down. If you want it to swirl like the coin you will need to counter gravity with centrifugal force, and reduce friction.

[@rhiantaylor3446]

Back in the late 1960's I had a physics teacher who came back from some kind of refresher course where they had used a special light (mercury arc ?) which made visible the mercury vapour that tends to arise when you play with the liquid. I don't really remember the detail - just that he said he was no longer inclined to play with the stuff to avoid risk of heavy metal poisoning.

[@electronicsNmore]

Every time I see Mercury, I think of German WW2 subs that were sunk in the ocean carrying mercury as ballast.

[@brendonwood7595]

I would be far more concerned about the amount of lead sprayed all over europe and the pacific from small arms ammunition.

Actually, you should be more concerned about all the lead solder that was used in city water and residential supply lines....far worse.

[@safir2241]

Cody'sLab What?! I’m so incredibly confused at why people are reporting chemistry content. You’re using what people learn in school in real life examples! Makes me trigger.

[@Stoned2daBone-r4g]

Maybe they link "home science" to ideas of terrorism and extremism because of anything Cody ever did with explosives or flammable materials? Which is some BS.

[@dementionalpotato]

I remember a video that he made a while ago that I think got removed. In this video, Cody shows, witch quite some detail, how to produce dynamite from off-the-shelf ingredients. I don't know how many videos of the sort he's made, but I'm guessing, and with limited knowledge of the issue at hand, that it's these types of videos that would get him in trouble, and not his average harmless educational videos that he uploads mostly.
