As a first-grader in the 70s I painted a rock to look like a beetle with rainbow wings. For decades I've wondered why I did that. Now I know I was seeing iridescence. Everything looks more amazing to first-graders and scientists.
As an artist, I love iridescent paints! When for the very first time I could paint a dragonfly as it really is, I think I died and went to heaven. I could spend days in the backrooms of that museum, just drinking the colors in.

I'm rather curious about two things: 1) How are stones/minerals like agates, jasper, morrisonite and others formed, and 2) Why do some minerals fluoresce under UV light?
Fluoresce is actually so much cooler than anyone could imagine! To keep it fairly simple, most of us are already aware of the fact that light can exist both above and below the visible spectrum our eyes perceive as color. Inferred refers to light waves larger than what we see as Red; Ultraviolet - the key component in fluorescence - is light waves smaller than what we see as Violet. When light reflects off an object, it absorbs all but the light we see, so something red ironically absorbs everything but red, so the reflected light we see is red. This explains the vast majority of what we see. However, there are certain colors that don't just reflect back what isn't absorbed. Instead, they'll absorb some and reflect the rest back at a lower energy level. Under normal light, this simply shifts the color slightly. However, when lit with near ultraviolet light (such as a black light), the material can absorb some of it, and reflect the rest in a lower energy state. When that lower energy state dips into our visible spectrum, it often appears like bright vibrant light is suddenly pouring out of pigments which otherwise appear dimly lit. In reality, it's very well lit - but it's not until the light falls just within the visible spectrum, that you can see just how much light is actually there.
Hey JDubyafoto, I’m a geologist undergrad and I’m happy to answer your first question. Minerals form when liquids turn to solids in the earths crust. When a magma is cooling some bits in it(magnesium, oxygen, silica) join together into the mineral olivine. Then the magma with olivine in it can go on to precipitate other minerals like pyroxene, amphibole, and biotite. But not all minerals form from cooling magma, some can form right out of water. As heated water is passing through a crack in a rock it picks up atoms of iron, calcium, silica… all sorts of stuff, then recombines them into a crystalline structure like quartz. Water could also carry dissolved salt (NaCl) and leave behind a crust of halite in a dried up puddle. I hope this helps
My research involves studying Cyanobacteria and I have always been fascinated with the array of colors packed within these microorganisms. There is deep blue from phycoyanin, light pink from erythrophycocyanin, green from chlorophyll, and yellow from carotenes and xanthophylls. How colorful is the life on Earth!! Thank you, Joe 😀
13:57 Labradorite 14:10 Hematite (a ferrous oxide, in the family of common rust/limonite) Remember: Nature is awesome. (just as the sciences who study it)
What is also really interesting is that our brains are capable of perceiving this beauty, and perceiving it AS beauty (as well as fascinating, and stimulating to look into the why of things, etc.)!
it is to be expected: What we call "visible light" happens to be the part of the electro-magnetic spectrum which is most strongly affected by atomic/molecular structure, which means that having organs attuned to this part of the spectrum (i.e. our eyes) helps us to perceive something of the chemistry of materials without having to touch them or taste them, so for example we can perceive wetness or dryness, or whether a fruit is ripe or rotten - all useful for species survival, and these basic perceptions contribute to the foundation of what we call "aesthetics" and "beauty" and significant aspects of culture - just think of a bowl of ripe strawberries with cream and sugar, or a well-cut diamond, or consider why ice cold beer is usually served in glass, rather than (say) porcelain.
The science-y bit is okay and all, but man, having rocks, fossils, beetles, museums --some of the most uninteresting words --in one short video and making it interesting. You are a legend...
I cannot believe how intriguing this is. It has been infront of me this entire time, just in my garden there are beetles and birds that have this. I never would have though so deeply about a beauty that I took for granted my entire life.
I just love iridescence! About a week ago, my family and I decided to head off to the National Aviary in Pittsburgh, PA. Best trip ever! We got to see some incredible birds and some of them had that same trick. There was even a volunteer that had bird feathers and showed us that incredible trick. Even blue jays do it and I NEVER knew about it until last week. It was the coolest trip I've done so far.☺️
Joe...you got loads of great content, but I think this one is your best so far. Can't stop ooh-ing and aahh-ing like a kid for the whole video. Thank you, it's such a delightful watch ❤️
I used to have a 2nd story balcony that looked out over a big yard; I put a hummingbird feeder on a very small tree nearby, and was delighted to realize just how gorgeous the little critters are from above--especially nice since they don't see you up there, and therefore you don't get dive-bombed by the more territorial ones! They're small and pretty, but they're fierce!
I have a chrysina species/jeweled scarab beetle in resin dangling from my neck have been wearing it everyday for years, I was actually holding it up to the sunlight and looking at it when you showed one in the video 🐸 love this video and all your content, thank you for teaching us 💗
Oh gosh! Got to put up hummingbird feeder! Love the green variations! Have some lovely iridescent 🪲 in my yard. My fav is the iridescent sweat bees and pollination bees. Found out the iridescent pollination bee-flies are actually endangered.
Rockhounding has become a recent hobby of mine since I moved to central NC a few years back. Just something about the colors, thinking of all the history it’s seen, the mix of elements, seeing cool clear striations and of all the rocks I’ve seen? What is on screen @1:56 is probably one of the most beautiful rock/ gem formations I think I’ve ever seen and probably will ever see. What I wouldn’t give to have that mastery of nature in a nice frame on my wall. I’d stare at it for hours.
Great presentation! I’ve liked iridescence and opalescence all my life. I have a collection of iridescent beetles I bought from a fellow I met at a craft show. He imported dehydrated ethically harvested insects from all over the world. Made the walnut frames and mounted the insects himself. My bedroom is my bug room and I love it. Now my adult kids are picking and choosing the ones they want! Gifting them to my grandkids, 11 and 6, instead. They love to sleep in Grandma’s room with the bugs. 🇨🇦🖖🏻🇨🇦
Here in my country Paraguay, I usually see some iridescent green flies enter my house, although it is not very noticeable with the naked eye until you mark it with sunlight or the light of a flashlight... and of course, IT IS VERY ANNOYING. XD
Great video. As an entomogist/arachnologist working in a museum, and helping in choosing a varietey of displayed invertebrates for a renowing of the exhibition in 2016, I recognized quite some of the beautiful beetles you showed. Simplay because they are so impressive. I will never stop being blown away and absolutely fascinated by so much perfect beauty.
Maybe do a color video on the Florescent color of corals from the ocean. That has to be the wildest color schemes you can find in nature. I can't think of anything that glows as well as corals do.
I wonder if there has been any study of this iridescent effect, but for frequencies below the visible spectrum? I imagine they would interfere at larger scales than these micro arrangements, right?. What would be the scale of the pits/shapes needed to create "iridescence" in radio waves? Is there a low enough frequency of radio wave, in which something like gravel or sand might become iridescent in some sense?
Everytime I watch one of his videos I can't help but be amazed for everything I learn and how much does he know. But what amazes me the most it's how can I be attracted to someone's intelligence and knowledge. Definitely I have a crush on him.
I have always loved iridescence and have many pieces in my closet that reflect this. AWESOME episode! Did I say I loved it? I think I am actually obsessed!
There's some weird beetle here in Missouri that we don't have up north that is scarab shaped, green/blue/ gold with a black and white striped abdomen. No clue what it was, but it was pretty.
We have peacocks and peahens, and in the summer we have SO many Ruby Throated Hummingbirds. I'm quite biased toward the incredible beauty of our peababies, but those hummingbirds are just as beautiful.
I've never thought that I could be so amazed by looking at dead animals and rocks💀💀, anyway very interesting things that we usually don't get to ask much about are sometimes the most beautiful ones thanks for kepping us curious Joe!
When I was a middle school librarian, I had a USB microscope hooked up to a huge monitor with tons of samples of cool things to look at. The greatest thing of all to see magnified 200X was the peacock feather. Magnificent.
I’m confused: you mention refraction and bending several times but the diagrams only show reflection and interference. Is the bending of different wavelengths of light at different angles involved but not shown?
I think the animations were not very useful today. I would have preferred white light entering, or at least a couple of different coloured rays, so the effects of interference on different wavelengths and angles of reception could have been shown
10:20 the "glittered weevil". These are actually quite common in central Europe where I'm from (genera Polydrusus and Phyllobius mostly). I'm a biologist working in invertebrates (mostly insects and spiders), and I absolutely love these. I find them cute as well. (not so fun to ID the exact species though. In fact, I'll give them to the weevil expert colleque because how complex their diversity is). But what's baffling is that these in particular look black as soon as you put them in liquid (in traps, for conservation etc.) It's obvious they do, because the whole wavelenght trick was designed for air. Water breaks light differently, so it does not work then. Also have to be careful handling and mounting them, since the iridescence come from the numerous scale like structures. If you touch to firmly, you'd brush them off and see the simple darkish actual color ofb the chitin skeleton. In fact, old beetles may have lost some scales just from living and be only partly iridescent. Similar for butterflies btw. (who have "scales" on their wings as well)
I have Austrolorp hens in my back yard. They are a beautiful black with iridescent green and purple on the feathers. Talk about beautiful chickens! They are also known for their sweet personalities. It's snowing in Tucson tonight. I hope our hummingbirds and finches are dealing with it well. I love both but especially the Goldfinches.
Could you make a video in this rock lab? I'm sure there's a ton of incredible crystal's ! Also a good close subject is the color of metals, why copper color is this particular? Same for gold and so on
I'm wondering; you talked about really thin layers reflecting light at different wavelengths to create iridescence, so why aren't clay particles iridescent? I'm thinking that they are extremely small and do stack in these layers amongst themselves. Just a thought!
Liking, commenting, and already subscribed! ^‿^ Thank you for this glorious little light show. Organically evolved diffraction gratings are so gorgeous!
Here in Central Brazil I see those iridescent blue morpho butterflies everytime I go to birdwatching, it's simply a privilege and a pleasure. The morphos I see here are mostly Morpho menelaus and Morpho helenor.
Awesome. Same iridescent effect the "Leiopython albertisii, a.k.a. D'Albert's water python. Or white lipped python" has in its scales. The snake looks copper brown or bronze colored. But in sunlight or some full spectrum artificial lights. The skin flares up in a rainbow color, similar to oil slick on water. There are others species of pythons that have this iridescent effect. But I personally like the white lipped because of its personality.
7:30 This is shockingly incorrect. Evolution (what he calls "nature") can produce phenotypes (what he calls "changes") that persist despite not providing a reproductive advantage (what he calls "purpose"). This can be caused by genetic drift, vestiges, etc.
The bug on your thumbnail is named rose bug in Germany and is very protected because very endangered. I had two of them visiting my balcony garden. I love them. The put their larva in my old left overs after the hardest and consume the roots. Next year I have recycled earth in my compost.
The Sunbeam Snake may be the most iridescent.... *Thing* I can think of. Snakes are highly iridescent especially when a lot of melanin is present like in IMG boas or certain designer Reticulated Pythons. But the Sunbeam Snake does things specifically to be iridescent and they are very cool. And chill. Ironically they are fossorial so ya don't see them much outside captive bred specimens and some on the hunt in the wild occasionally lol
I've bought an iridescent colored necktie and havent found anything about this effect. Thanks a lot for feeding my curiosity. Greetings from Germany, Batthias

2:52 Science is based off of facts but it is also a fact that it is always based off of "we thinks".
Amazing how the iridescent colors remain vibrant and alive even after the birds have been dead for so long .
“All light enters, only some light leaves.”
Everytime I watch one of his videos I can't help but be amazed for everything I learn and how much does he know. But what amazes me the most it's how can I be attracted to someone's intelligence and knowledge.
Definitely I have a crush on him.
The opalized whalebone is amazing.
When I take shrooms, iridescence is everywhere
and it's God damn beautiful 😫
Literally asked myself how does iridescence work 3 hours ago watching a hank green short on bismuth
OOOOOOOH, all the lovely eye candy! I'm hooked on iridescence, & hope to acquire an opalized ammonite some day.
I have always loved iridescence and have many pieces in my closet that reflect this. AWESOME episode! Did I say I loved it? I think I am actually obsessed!
There's some weird beetle here in Missouri that we don't have up north that is scarab shaped, green/blue/ gold with a black and white striped abdomen. No clue what it was, but it was pretty.
One of my FAVORITE effects in nature!
Hi Joe, Bob here. Isn’t nature amazing! Great episode.😊
Spot on Beatles impression at the end 😂
We have peacocks and peahens, and in the summer we have SO many Ruby Throated Hummingbirds. I'm quite biased toward the incredible beauty of our peababies, but those hummingbirds are just as beautiful.
I love these videos wish they came out more frequently.
Well, good to know that the Earth and I are both fond of jewel-tones. 😉
I was wondering if octopus or squid would be on this because of iridophores (which are underneath chromatophores) they're so cool
I've never thought that I could be so amazed by looking at dead animals and rocks💀💀, anyway very interesting things that we usually don't get to ask much about are sometimes the most beautiful ones thanks for kepping us curious Joe!
When I was a middle school librarian, I had a USB microscope hooked up to a huge monitor with tons of samples of cool things to look at. The greatest thing of all to see magnified 200X was the peacock feather. Magnificent.
I’m confused: you mention refraction and bending several times but the diagrams only show reflection and interference. Is the bending of different wavelengths of light at different angles involved but not shown?
I think the animations were not very useful today. I would have preferred white light entering, or at least a couple of different coloured rays, so the effects of interference on different wavelengths and angles of reception could have been shown
Its the Beauty of Chaos divided!
Birds! My very favorite forms of animals.
10:20 the "glittered weevil". These are actually quite common in central Europe where I'm from (genera Polydrusus and Phyllobius mostly). I'm a biologist working in invertebrates (mostly insects and spiders), and I absolutely love these. I find them cute as well. (not so fun to ID the exact species though. In fact, I'll give them to the weevil expert colleque because how complex their diversity is). But what's baffling is that these in particular look black as soon as you put them in liquid (in traps, for conservation etc.) It's obvious they do, because the whole wavelenght trick was designed for air. Water breaks light differently, so it does not work then.
Also have to be careful handling and mounting them, since the iridescence come from the numerous scale like structures. If you touch to firmly, you'd brush them off and see the simple darkish actual color ofb the chitin skeleton. In fact, old beetles may have lost some scales just from living and be only partly iridescent.
Similar for butterflies btw. (who have "scales" on their wings as well)
Came for the science, stayed for the puns. Seriously, their were... Brilliant
I have Austrolorp hens in my back yard. They are a beautiful black with iridescent green and purple on the feathers. Talk about beautiful chickens! They are also known for their sweet personalities. It's snowing in Tucson tonight. I hope our hummingbirds and finches are dealing with it well. I love both but especially the Goldfinches.
Can we take a moment to appreciate how we have two eyes to give the amazing shimmering effect it has?
I freaking love opalized fossils! :D they are the rarest i think
So happy you’re back!
Could you make a video in this rock lab? I'm sure there's a ton of incredible crystal's !
Also a good close subject is the color of metals, why copper color is this particular? Same for gold and so on
Very good video! Educacional, lighthearted and some of the most beautifull animals/stones i have seen. Thanks
I'm wondering; you talked about really thin layers reflecting light at different wavelengths to create iridescence, so why aren't clay particles iridescent? I'm thinking that they are extremely small and do stack in these layers amongst themselves. Just a thought!
Maybe they absorb too much light. The silica in opals is basically glass, so much more transparent particles.
I've seen iridescence on fresh clay! It was very subtle though, and only once.
Liking, commenting, and already subscribed! ^‿^
Thank you for this glorious little light show. Organically evolved diffraction gratings are so gorgeous!
Happy Birthday, Ringo Starr. Long live the Beatles!
Here in Central Brazil I see those iridescent blue morpho butterflies everytime I go to birdwatching, it's simply a privilege and a pleasure. The morphos I see here are mostly Morpho menelaus and Morpho helenor.
Plants do this too. The jewel orchid, and philodendron micans also have microscopic crystalline structures in the leaves. Plenty of other examples too
A while back I had a dream about a horse with iridescent blue hair.
Awesome.
Same iridescent effect the "Leiopython albertisii, a.k.a. D'Albert's water python. Or white lipped python" has in its scales. The snake looks copper brown or bronze colored. But in sunlight or some full spectrum artificial lights. The skin flares up in a rainbow color, similar to oil slick on water. There are others species of pythons that have this iridescent effect. But I personally like the white lipped because of its personality.
Amazing video
7:30 This is shockingly incorrect. Evolution (what he calls "nature") can produce phenotypes (what he calls "changes") that persist despite not providing a reproductive advantage (what he calls "purpose"). This can be caused by genetic drift, vestiges, etc.
Great video. Thank you
Joe puts so much efforts in the video 😭 keep making us curious
The birdwing joke flew right over my head.
The bug on your thumbnail is named rose bug in Germany and is very protected because very endangered. I had two of them visiting my balcony garden. I love them. The put their larva in my old left overs after the hardest and consume the roots. Next year I have recycled earth in my compost.
The Sunbeam Snake may be the most iridescent.... *Thing* I can think of. Snakes are highly iridescent especially when a lot of melanin is present like in IMG boas or certain designer Reticulated Pythons. But the Sunbeam Snake does things specifically to be iridescent and they are very cool. And chill. Ironically they are fossorial so ya don't see them much outside captive bred specimens and some on the hunt in the wild occasionally lol
Very informative and very beautiful. Thank you!
The "Bird - Wing" joke was good.Really 👏🏻👏🏻🤟🏻
Forget bugs, some of the Iridescence is already found in fishes.
I've bought an
iridescent colored necktie and havent found anything about this effect. Thanks a lot for feeding my curiosity.
Greetings from Germany,
Batthias
I think that butterflies and tropical fish drew the short straws in this video......... Should have at least gotten an honorable mention ...............
