No, no. It's hoarding, because it hurts less when you need the thing a few weeks after you finally threw it away after storing for years. That way it's unfortunate timing, rather than a failure of foresight and planning.

We should all be so lucky as to have some mildly diluted ink sitting around. You never know.

There are microfluidic devices called spiral separators. These are usually use separate different cells based on density. Probably not useful for sorting ink, but might be worth a try for fluorescent polystyrene particles?

What you want is ultrasonic separation. This is used in grand scale industrial applications. Basically using standing waves to "catch" particles. But be warned, that's a rabbit hole on it's own.

17:55 The problem you had with the endcaps leaking might not actually be solved. Waterproofing 3d prints is notoriously hard because of the pores they have between the layers. This can be helped by extra perimeters and higher temperatures like you did, or smoothing the part by dissolving the surface with isopropyl alcohol vapors. However, most 3D printable plastics (like PLA and PETG which you used) are hydroscopic, which means that the plastic itself will absorb water. At very high pressure differences, like your 100 psi chamber, the water will still be forced through the plastic. A lot of submersibles with 3d printed parts have the same problem. You can try high-impact polystyrene (HIPS), which is not very hydroscopic.

I am a bad person - the word is hyGroscopic. ABS would work, and is extremely easy to vapour smooth using acetone. It is often used for pressurised water pipes.

@benjaminangmingteck8332

Ай бұрын

The trick to printing a water tight end cap with petg is to use concentric solid infill with chamfers on the bottom. Because of the chamfers, each successive layer of concentric infill is offset from the one below it ensuring there's no straightforward path for the water through the print. You can also separate the print into an outer shell printed in vase mode for watertightness, and an internal part with the more complex geometry. I print canister filters for aquaculture this way. You can also thin pvc glue with acetone and use it as a water proof coating in a pinch.

@bastienx8

Ай бұрын

There are multiple things to consider with hygroscopic materials, in particular "how much" water it can absorb, and "how hard" it absorb water. PETG for example does not absorb a lot of water (about 0.2% from what I've found) but it absorb it quickly, that's why a PETG spool is affected quicker with ambiant moisture than PLA. On the other hand PLA does not absorb water quickly but it can absorb a lot. And another thing, hygroscopic and water resistant are two different properties. Hygroscopic is about water absorption and water resistant is about degradation in water. PETG is water resistant (PET, PETE and PETG are used in plastic bottles) while PLA is not water resistant.

We absolutely need a This Old Tony response video talking about physics.

Your way of mixing science and engineering is infectious. Wacky ideas and none of them boring. Many of them people can do at home if they really wanted to.

Maybe try removing the flow restriction after the ink at regular intervals to wash away the ink fouling from your filter. Backflowing some water through the filter may also help clear the fouling, though I'm not sure if your filter can handle that.

If you coated the inside of the pipe wifh a superhydrophobic substance, you would get different flow characteristics. Might be worth a try!

The whole thought process and discovery journey is awesome! Cool project and very impressive!

Great job! This is personally interesting as my 3 year old grandson ask his parents what turbulence is which they passed on to me. So I made a little movie for him using a coffee carafe and food coloring. I spun up the water and let it settle and become laminar, then added a couple of drops of food coloring. Due to some remaining shear it formed cylinders that were remarkably stable. Introducing a small diameter cylinder provided great turbulence on the backside. My grandson got through at least half of it before he got bored.

whenever you upload, not only is it incredibly interesting and educating, but the experiments, demonstrations and contraptions you come up with are so unique. you have a special mind, thanks for sharing that with us.

This is amazing, especially how you can see the transition from turbulent to laminar. Loved the “Now I’m getting graphs like *that*” too lol :)

This has the same mesmerizing details as sometimes looking at the sky and the cloud details. Love it.

Enjoyed learning about this project! In my automotive electrical class, my instructor compared voltage to pressure in a water hose. Lots of similarities between hydraulic and electronic circuits as well. Understanding one helps understand the other- you're not weird for thinking that way!

I am so ready for the reverse osmosis video. I fell down the rabbit hole when I put one in for my ice maker, but I'm sure you'll go much deeper with your video.

You had me at "better than a lava lamp" I love lava lamps. Edit: Even better idea: Use smoke and a laser array instead of water. Still fluid but you're using one fluid instead of two so you don't have to filter anything.

The patterns at the end of the pipe really remind me of surfaces of gas planets. I would be really cool to have the same thing as two spheres where the liquid moves between a inner spinning and an outer static sphere

Makes me think of the overall flow of a human life. Thank you.

Loved this project! ❤

I really enjoyed this video, thank you Brian!!!

This would be the sickest desk lamp. Take my money.

Please DO make a building sized one of these :D

Here is an idea. Use a higher viscosity fluid. Second, use a magnetic ink and use a magnet to re-separate them, no filter. PS brilliant and beautiful work 🥰

I can see that watching this after a stressful day can have soothing effects.

The shot at 5:34 is just stunning

I had a very similar idea a couple weeks ago but using mica in solution instead! Great work as always! Cheers from Texas!

Awesome video. thank you for making it!

As always an amazing show mate

your videos are so soothing

A fluid will always have laminar flow when is being sucked. Versa, it will always exhibit turbulent flow when is being pushed ( under pressure ). These 2 behaviors are governed by the local dynamic impedance. When a fluid is sucked, the suction effect creates zones of under-pressure which allow the fluid to start organizing (moving) itself through the path of least resistance/impedance and such, given enough time creates laminar though the engine fluid can have a curl gradient.

just like the Falling/Flowing Sand toys, very fun to watch.

Another excellent video. Thank you.

Very nice I am currently working on simulating bleeder mixing in saline Irrigation.. I appreciate your passion for such things

Lovely video, congrats!

My left ear really likes that bell sound!

To make the filters last longer instead of ink use a long polymer of plastic with dark colour. Think tiny micro plastic beads that will be as fine as ink but easily stopped through a filter/

Cant wait for the next video!

I absolutely love "mad science" channels like this one. Maybe one of my favorite things about the modern internet. Thanks!

At first I was wondering why you didn't go for the classic mica in water approach, but by the end I understood it wasn't about the turbulent and laminar flow as much as it was about mixing and diffusion in total.

Once again a very cool video (and idea in general)! Beautiful visuals, clever mechanics and interesting physics - what more could you want?

I work with heating networks (which is mostly just a bunch of water flowing through pipes) and there we also think of it as analogous to electrical circuits a lot! Basically the water flow throughout the network follows Kirchhoffs laws, and the "resistance" of a pipe is modeled as being dependent on the flow speed (because fast moving water will become more turbulent and so encounter more friction). It's a pretty effective analogy!

i always watch and love your videos. today i was pretty tired. i fell asleep during this one and woke up at the end.

Neat. I've seen reversible mixing with a cylinder rotated one way to mix, the other way to unmix, using a viscous fluid.

Laminar flow. You just became Destin's best friend.

So looking forward to the next video

It's a very cool project for sure! I think the filters clogging is normal, on saltwater desalination they reverse flush the filters at certain times to unclog the pores and have a secondary pressurized loop for this. You could put in a second loop that does a reverse flush with clean water every so often. Of coure the ink could bind to the filter relatively permanentely then you would need different material for the filter (I mean you only need the ink not to go through, right, does not have to filter down to water atoms), but putting a reverse-flush on a timer could extend the life of the system at least a bit.

This is like the fractionated elutriation filtered, color coded particle size, patterned laminar flow layer disruption display, from my impossible to implement ideas notebook. I'd love to see this with rheoscopic fluid, maybe laser planes, and remote control disruptions for things like vortex shedding analysis, to visualize even more more complex currents.

reverse osmosis filters need regular flushing through the 'brine' or 'waste' outlet to keep the membrane from clogging, and extend its lifetime by at least double.

you are literally my favorite youtuber

Back with another banger.

I was thinking about how to remove the particulate from the water more efficiently. Some kind of prefilter would probably be very useful, maybe a cyclonic filter? Or perhaps with a different ink, you could use biphasic solvent separation?

I'm already looking forward for the osmosis video! That's something I would love to understand better (I can currently understand what happens but not why it happens).

The reverse osmosis filter require rinsing flow on the outside of the membrane to keep it clean. Even with just tap water it would plug if it wasn't dumping water down the drain. Then you are restrcting the output of side, worsening the problem. I would consider recirculating the pumped mixture to keep the flow moving on the outside the membrane

I watched Destin’s ~4-hour video where he did fun stuff with ink and water. This is a surprisingly well-served art form on KZread.

I'm pretty sure fluid dynamics and turbulent flow is one of my utmost favorite things in nature.

more spectacular than Jupiter's equatorial flow is hard to beat :)

Amazing video and looking forward to the entropy episode next! I always got E's and F's in math at school but now, many years later, I think that might have been down to how it was taught to me and it just wasn't a good fit. Thanks!
