Glass | SciShow Tangents Podcast

[@Arwennigan]

2:03 Oh my god, this was me. I feel so seen. I regret not listening to this episode right away. Sorry I acted like such a dweeb! It’s so funny because I’m known for being chill, but I was freaking out when I won that round of trivia. I was not prepared to be on camera that day and it SHOWED. 😅😅😅

[@jg613887]

Yes! I recently found this show and blew through them all, now i get a new one

[@ashleelarsen2233]

Pandemic problems 23:45 sweet home Alabama, right?

[@CyrynDragoon]

Another SciShow Tangents... Another episode without my wish of a coffee table book of poems... As promised, I will be posting on EVERY episode in a futile effort to convince you to publish a book of the poetry from this series... ALL the poetry... The good, the bad, and the silly! I wrote a crappy haiku to try and convince you that you need to make this happen: Coffee tables bare, Poems read at the starting bell Would fit nicely there....

[@nessidoe8080]

Yes, we NEED the SST poems coffe table book! We won't give up! It will make me smile every day

[@SciShowTangents]

Maybe not entirely futile!!

[@CyrynDragoon]

@@SciShowTangents OMG! I can't decide between fangirling that you noticed or excited that it might happen!!! I'm sooo happy I could burst! ^.^

[@T_Armstrong]

This is so wholesome 🥰 Their poems are proof that science is an artform

[@KOKO-uu7yd]

YESYESYES!!!!

[@saahirga4476]

I'm a materials science student, and we talked about the Lycurgus cup in one of our classes. To answer the question of how they made nanoparticles in ancient times, what you do is you put a small amount of gold/silver in the glass, heat the glass up to dissolve the gold/silver uniformly into the glass (which is called solutionizing), and then hold the glass at a lower (but still elevated) temperature where the gold/silver atoms are mobile in the glass, but are not very soluble, so they dissolve out of the glass to form tiny nanoparticles.

[@kalef2]

Couldn't help but imagine that as cooking instructions for slow roasting your glass to help all the color flavoring really come out in the final product. Also, now I wonder if you could do something similar with sugar, but I don't know enough to know if there's an edible colorant that could be dissolved into molten sugar to behave that way.

[@kyle-silver]

I listen to tangents every night to fall asleep to. I feel like most of the facts are now stored deep in my subconscious… I regularly wake up with the work “blectar” on my mind with no idea of how it got there

[@ch3rrrr]

me too

[@ivytarablair]

way to go those of us who listen to all the Tangents eps over and over :D Tangents is my falling-asleep audio on a timer every night, on all my car trips, and whenever i do chores. I just love learning so much in so much detail, and getting to enjoy hearing you all have so much fun. PLUS Y'ALL'S POETRY IS DELIGHTFUL AND I HOPE SOMEONE PUTS IT TOGETHER IN A BOOK AT SOME POINT 😂 both the wonderful ones and the awful ones and the 'Wow, poets have been Created!' ones.

[@davidhodges2741]

I found the podcast recently. It's like listening to friends every day while i catch up. A conversation with this group would be a dream regardless of the topic

[@tjthrash0143]

We need more sea shanty. Ceri's was awesome.

[@gordonwerner]

Well, as Hank informed us today, we’ve figured out ancient Roman concrete … so maybe ancient Roman dichroic glass will be next

[@IceMetalPunk]

A commenter named Saahir Ga (somewhere ⬆️ up there... or ⬇️ down there.... or somewhere...) explained it! 😁

[@thegameres816]

So happy I checked on the channel! I have 2 episodes to start my morning with! Hope everyone has a wonderful day!

[@dead1097]

Good to know I'm not the only one who listens to these over and over! It's one of my hyperfixations now, I have no joy when washing the dishes without it.

[@ShadeAssault]

The Science Couch section reminded me of a time that my step-dad and I never let my mom forget. They store pots and pans in the oven and one day she turned the oven on to pre-heat for something and forgot to take the pot with its lid out of the oven. Well at about 350F, she realized and yanked it out. The plastic handle on the lid had completely melted, but it was still hot. So she decided to put it outside to cool it down. This was in January, in Pennsylvania, right after a snowstorm. She put the glass lid directly on top of the snow. We both yelled at her that it was going to shatter, somehow it did not. She still has that pot and lid.

[@GlassMunky]

You guys should look up CFL glass colors A newer invention in the past decade or so, by using holmium or other rare earths you can get glass that changes colors based on the light source that hits it. Super neat.

[@SamLugo]

They tried to trick me with this episide about glass, but I saw right through it.

[@ponyote]

My mind has been lighted. Thanks!

[@itsponygirl]

"now you can jump through em all day long" 😂

[@diananoss9931]

Hank looks especially handsome in this episode :)

[@avsgriffy]

This show releases at noon where I live. I'm on my lunch, but don’t have reception in or near the building 😢 If I'm home on a Tuesday its always on my mind

[@KOZMOuvBORG]

8:37 it's wasn't until we learned to float (method) glass on molten tin that we got even panes for windows

[@NicholasHay1982]

Social media has duped us into thinking it's *normal* to have a public and publicizable part of your life. It's one thing if you choose to work in the public sphere in some capacity, but when I see normal people one-up each other by talking about losing followers and not getting whatever form of engagement the platform pushes... I has a sad. But then I post about it from the privacy of my own social media account, and my actual real friends mostly ignore it and I find some SciShow to listen to instead.

[@therabbithat]

It's the using your real name to talk to strangers or acrew online clout is weird. Your name is for you and private life IRL, your handle is for your internet friends who know the real you because of IRC or whatever, never the twain were to meet

[@Aeleas]

I'm so glad I got in on the Hank follow before he went private.

[@katetoolate234]

14:54 Oh dang, I just realized that one Veggie Tales "A Christmas Star"? movie from my childhood was more historically accurate than I had given it credit for!

[@fiona4407]

I love that exhibit at Harvard! It'd be amazing if y'all made an event of going to see it! I'd absolutely come! 22:08

[@katetoolate234]

I have no idea why it only occurred to me NOW but when they were talking at the top about the person who'd watched all of SciShow Tangents.. it occurred to me.. that I havent seen a SciShow video in months! I used to watch them all the time and then I think they drifted out of my recommendations without me noticing because I still had Tangents (and other educational Hank Green channels) in my feed. 😅 Anyway, I've got some catching up to do!

[@jess53nz]

Don't worry Sam, i heard attacks on glass too!

[@JHaven-lg7lj]

The pieces that tempered glass shatters into aren’t rounded, they’re actually plenty sharp. Mythbusters did an episode on it, it was startling

[@arthursamuel301]

Is THAT why we don't get more SciShow Quiz Show? The Table Accident?

[@NicholasHay1982]

I like to think at the end, when Hank said "It's a hole thing," that's the spelling he would have used.

[@victoriaeads6126]

I was at the Corning Museum of Glass in the 1990s. They were talking with bated breath about this new stuff they were working on called "fiber optics." At the time they were still having trouble with making it appropriately flexible, so they weren't sure whether it would end up catching on. Spoiler: they figured it out.

[@dummyinblue]

Omg release the list, I want to quiz myself! Lol

[@billclinton1235]

Love every episode. But I'll have to leave work so I'll miss this primer 😢

[@katetoolate234]

We had a glass table shatter on us once when I was a kid... We didn't see it happen, but found it the next day. I remember all those little pieces, though..

[@DCII]

100% of glass tabletops will explode or be exploded. The only alternative is to untemper it before breaking the glass in the process of recycling, which there is no reason to waste that energy.

[@billie8713]

The ending music kicking in makes me jump every time! 🤣 I'll never forget hearing for my mom when I was younger and my sister was in the hospital and she was staying at the Ronald McDonald House that another mother was there to her child who fell through a glass coffee table and it killed one of her kids in like almost cut in half like her other kids who was barely hanging on and I have never in my life bought any glass Furniture ever as a result!, and I never will because I have my own kids

[@bojassem12]

Ceri is the in pocket of big glass!

[@OnceUponATimeLori]

Holy shitballs Batman, I just went to the Ware exhibit of glass flowers (and aquatic animals) at the Harvard Natural History Museum and it BLEW MY MIND! 🌿🌻🪴🌼🌾 Thank you! Thank you! Thank you! For being some of the best science communicators out there. I am in so much awe of this project. My stomach was literally turning in knots when I was there. It's exceptional and everyone should visit. ❤

[@timothywhite5453]

Sad Jolly Ranchers didn’t make an appearance in the episode!

[@rebecculousrk]

This was the first time I ever saw Sam. In my head, I was picturing Jonah Hill, I don’t know why. 😂

[@mikkosaarinen3225]

The only glass things I've seen explode are glasses, especially wine glasses.

[@bananatassium7009]

6:12 this is interesting, i had heard it was more to do with concrete production, do they both play a part?

[@nurfuerdieplaylist]

From my understanding, sand is kind of an umbrella term for solid particles of a specific size range, so not very particular in terms of chemical composition. I guess there are different shortages of different types of sand maybe? For concrete I think most sand is useless because the particles are too smooth from abrasion over long periods of time and don't interlock as well as younger, more jagged ones.

[@IchBin-meh]

very cool

[@CheeseBallsNBeanDip]

I'm so happy I already follow Hank!! I'm not on twitter, like, ever, but I have the option 😃

[@nailkandy4429]

Re: spontaneous glass explosion - an empty wine glass on the counter spontaneously exploded, and it had not recently been manipulated in any way. The only reasonable explanation I can imagine is that maybe a large truck drove by and sent a vibration through the house at just the right frequency to release enough energy into the wine glass to cause it to fracture. 🤷‍♀️

[@Syco108]

And I've been entertained

[@ditzfough]

Please ask Tom Scott to Guest appear on Tangents please.

[@LaceNWhisky]

Yes Hank. Glass up the butt *is* a "hole" thing.

[@jon_franklin]

So obviously I counted the number of windows in my house (UK). Excluding the one on the front door we have 10 windows and one boarded up window. I wonder if the only window boarded up (the smallest in the house) was blocked to avoid the higher tax.

[@jon_franklin]

Upon further consideration, my house is only like a hundred years old so this has nothing to do with the window tax. "More than 10" figure, from the original 1696 introduction, of the tax was lowered to 8 by 1825 and the tax was abolished in 1851. So unless my house is three times as old as I think it is, I don't think my tiny boarded up window has anything to do with that.

[@edgarseis]

Oh no! Is the blue checkmark Hank has still that one? It made me really sad to see the blue check on his Twitter account :(

[@athanatic]

Glass making is one of the last technologies to be learned and lost. There are very old glasses that have a void of glass in the current historic record after them followed by a rediscovery. Steam engines do not count as Heron lived in a world of ubiquitous chattel slavery and we have actual writings describing the toys, so not really lost.

[@victoriaeads6126]

The sand shortage isn't so much about glass, it's mostly because of concrete production.

[@celebdae1341]

Come to mastodon

[@davidsasse40]

The sand shortage is due to sand used in concrete. Waaaaay more sand is used in concrete than glass.

[@AidanRatnage]

I miss SciShow Quiz Show.

[@kioshekat7931]

glass showers shattering "happen less often than you think" I disagree. FOUR shower doors shattered in the hotel I worked in in one year alone (though it is a very old hotel and in a ski resort so idk if the cold affects it)

[@rickgomez1277]

I honestly just found out last week that glasses are actually made of plastic!.. 😅 I was extremely confused about that fact. 👀 😮

[@ChrisD4335]

a lot of cell phone glasses are made of aluminum oxide these days

[@therabbithat]

Damn, I was following Hank but then I deleted my Twitter (long before the recent stuff) so I've lost my only chance to ever be in a special exclusive club (And someone else has my name now and I don't like what they are doing with it... Except when they post pictures of their dog)

[@IceMetalPunk]

Hank, I've lived in Florida my whole life, and I've never seen a garage door with windows in it... I think that must just be an Orlando thing 😂

[@xevsetter1201]

Because it is a super viscous liquid glasses is

[@Andre_the_Lion]

The amorphous/liquid problem of understanding glass seems to come from the fact that even different types of glass that the average person knowingly encounters are visually similar and colloquially just called "glass", as if it was a relatively restrictive category of materials like "stainless steel". In fact, firm definitions of glass tend to refer to a whole category of materials by structure, more akin to "metal".

[@robnol84]

Cell phone glass is wild it's like borosilicate glass.

[@BobSmith-tm2kj]

hehe, colonoscopies are a "hole thing" yes.

[@Pannekoek.]

I think Hank and Sam are got by experience bias. I have never known somebody that have had shower/furniture glass explode but I do know 2 people that have been struck by lightning (they both survived) I guess your sample size is to small to question glass manufacturing propaganda. I would expect more of science people! 😜

[@blessedveteran]

I deleted my twitter and Facebook
