One option for this sort of thing is to get a full CT scan of the device (there are industrial CT scanning companies that do this). You can export the geometry as an STL and print it directly out of a clear material. Some SLA resins have very good optical properties and might work for your purpose here without having to reduce the geometry to 2D. I do think the 2D versions do help to make it easier to understand the concepts sometimes though.

Lol, I had a similar story but the other way around. I remember watching these "fake 3D effect" videos and images that can trick your brain into thinking it's looking at a 3D image, by just crossing your eyes and focusing both images with each eye at the same time. But I didn't know it was called "stereogram". Also, to me I found quite difficult to recreate this stereogram, as the image was spinning around, and when it got to the back part of the whistle, my eyes just moved with it and lost the focus to the 3D image. I don't know if I explained myself correctly. English isn't my first language.

Thanks mate, your video was extremely accurate, was able to 3d print my own version with your information :D

I love the channel! I’m always curious about how things work.

Wow, that stereogram blew my mind! Keep up the great work man, love your videos!

Same, I was not ready for that

I'm obsessed about this type of mechanisms because this channel

I thought I was literally the only one who could go crosseyed and match images like that. I do it all the time with recurring patterns like bathroom tile, curtains. I never thought about using it to simulate something in 3D like that though, that was really cool.

Here's a fun illusion: from 2:05 a for a while after, which way is the pot turning? left or right? Some people can even "decide" a direction and it'll look like the pot is turning the direction.

I saw an exhibit at the Science Museum in London that demonstrated this with a rotating cube. They tell you to close your eyes and look again a few times. Each time you look at it your brain chooses a direction to interpret it as moving. It is because of the ambiguity between which lines are in front and behind.

I love how this has become the "transparent replica" channel. It's great and it cracks me up every time you do it.

If only Steve would start embracing the third dimension. An entire video of why a flat model didn't work, but no thought on making a wider one lol

what an amazing craftsmanship

you know it says alot about how you break down a subject that i can still follow along just fine having been awake for four days. always found it frustrating when someone would profess themselves to be teaching something or explaining something and you never actually get the answers to the how because it often gets left in a very stock way of explaining something without every bothering to break down each functional variable. great work

Me: goes into stereogram vision Steve: goes back to regular video without warning Me: 😵

"i dont want to break it" *proceeds to cut it in half

Wow! Awesome Stuff! I am thoroughly enjoyin you latest vids on fluids, reminds me of the one you did on resonance...

That was the best stereogram I've ever been able to see. I'M AMAZED!

My man just dropped the stereogram on us, like it was nothing. Blew my mind, it would be worth a video on its own!

Ooh they sound so nice. Could have been interesting to talk to someone who makes them but great video!

Always wondered about these and knew you’d get to them eventually thank you

I have to say,these whistles must have high tech behind them originally, but enough of the knowledge survived through the passing down of the art for generations.I think those are so beautiful .

3:53 makes me wonder what a 4D whistle might be like. What would its properties even be? How might fluids flow in a 4D structure? Would it be possible to simulate the sounds it produces, and would those sounds even be the same in different 3D slices of 4D space?

i've never seen a magic eye as a video! so cool how helpful that is to really understand the 3d model

I loved the stereoscopic view! It was amazing! Never have seen someone do it with video.

At this point Steve has developed an obsession for transparent 2D versions of weird vessels.

That's just him developing his own brand/image

Honestly, he should have asked the person who makes these to make a half of one instead of breaking it. It saddens me that someone's handiwork was destroyed.

Excellent video. I have been fascinated by these vessels for over 25 years (I am a musician and flutemaker). The restriction of airflow by the small relative area of the vent hole as compared to the volume of the water attempting to traverse between the chambers creates a backpressure situation which, as you correctly surmised, is not present in the 2D model. The backpressure helps to both regulate and accentuate the gluggle effect. Cheers.

I am from Perú, so to see a representation of my country in your channel really makes my day

Ok Steve you can tell us the truth. You're changing the name of the channel to: The amazing world of whistles with Steve Mould

@@SteveMould In the next video I attempt to use a Peruvian water whistle to hail a taxi in NYC. Coming later... One trick the whistle cartel doesn't want you to know! Love you Steve!

Holy crap, that stereogram thing TRIPPED ME OUT! I didn't know what to expect: I was moving my phone back and forth, in and out, in front of my face like madman when suddenly the 3d image just snapped into existence like a SHOCK, my phone disappeared and I was in a weird 3D VR brain mode. I mean, I think it was only shocking because I didn't know what to expect, but that was trippy!

Lol I’m Peruvian and honestly didn’t know about these, gonna be on the lookout for a couple of them to bring home next time I visit a handcrafts market.

Outstanding, beyond interesting. I can imagine them being used in old wise story telling to the younger generation back then.👍❤️

2:21 Kinda hard to do the whole "3d trick" when I've only got one eye. Note: The previous sentence is an example of self-deprecating sarcasm. It was not and is not in any way, shape, or form intended to insult or otherwise verbally assault the creator of this video. Note 2: For anyone that's curious, I lost my left eye to meningitis when I was 5 months old. I didn't lose it to some wacko with a gun, or had it gouged out by a shard of glass in a car accident. Just plain old surgery to save a little baby's life, nothing special.

Pretty soon I’m going to have to dedicate a whole shelf of my bookcase to the Steve Mould - cool whistle museum. Thanks for another awesome explainer Steve! PS: love to see the pebble still on your wrist

Besides buying one for myself, Steve inspired me to buy the man/woman Peruvian whistle as a gift for a newlywed couple. The whistle even comes with a romantic story. The man is lost and cries out (first whistle sound) for his wife. She respond, 'I'm here. Follow my voice" (second whistle). Then, you can make them both sing together. The couple and everyone else found the whistle delightful and romantic. So, Thanks, Steve!
