This Crystal Is ELECTRIC
There's a few minerals that exhibit something called piezoelectricity and pyroelectricity, which mean that either heat or pressure can turn them electric. Here's a demo from the SciShow Rocks Box where you can see this for yourself - all you need is some tourmaline!

This episode is FAR more visually engaging than the “host standing before green-screen”. 🎉Love it!!!
The filing cabinet with stuff crammed in it sticking out to the side is a very nice touch. There are two kinds of academics, the extremely excessively neat and the absolute chaos. I believe both are a case of drawing comfort from the atmosphere. And they are nothing if not incredibly consistent to encounter.
How do you know they're not? At least the majority of it are just things in the background. Stuff like that would be easy to do with green screen, and with AI, as well as of a combo of them. Stuff she holds is likely real, but no way to know on the rest. Depends what would be easier for them. Could be easier for them to ask some geologist to let them use their space and/or rocks. But maybe not. 🤷🏼♂️
quartz crystals used to run the clock rate of nearly every cpu/microprocessor out there and still run most digital clocks at 32.768 kHz
Used to? Don't they still provide the clock for pretty much everything?
@@tracyrreed kind of, you cant get a like a 4GHz clock out of a crystal alone but you combine it with a special circuit and you should, Im fuzzy on the details but something about using quartz reference and then generating higher clocks out of them.
The quartz gives the triggers for a single shot square wave generator. So the quartz is still the heart of the clock circuit. Though some are going to ceramic oscillators due to being more stable under varying temperatures
They’re still used in CPUs, particularly when they need to run in a low power state :)
I think they are still used in many transmitters as well, "crystal oscillators."
I'm glad Savannah got a cool office setup for this one, I like the format and it fits their vibe!
5:11 the way you said "bones?!" was really descriptive, lol. Like yes I agree with that inflection 100% because wtf 😅
We did this in Girl Scouts. Our troupe leader had a tourmaline which she set on a rock while cooking a marshmallow. She set it on fire, then blew it out and used the tourmaline to pull the ashes off it without disrupting the good part of the marshmallow. Pretty cool! (Ed: spelling. Thx ppl)
*marshmallow
@@philp4684 tomato/tamato
@@philp4684 A true fan of vocabulary knows that etymology is an ever changing variable in the way people speak. While it was originally called a marshmallow, I would dare say that most people pronounce it marshmellow these days. A similar situation would be duck tape versus duct tape, the former being the "correct" way to say it. Even your name has no doubt changed spelling and pronunciation over the centuries. Or, perhaps you are just a troll. Thanks for the awesome story sophiejones3554! Sounds like you had an amazing troupe and I am glad you experienced that.

Am I the only one old enough to have heard the Adam West-era Batman music in my head when they did the scene-change spinner at 6:12?
Not likely. Statistically and all. There's many viewers
@@Psilomuscimolholy taking things literally batman!
My whole job in the military revolved around this. We used the vibration of cesium crystals to keep absolute precise time with assets *very* far away. Pretty cool stuff!!
Not sure if you're referring to satellites, but there are satellites that not only use cesium-based atomic clocks, but also need to adjust their time keeping to account for time dilation, since they're so much further outside of Earth's gravitational well! (This means they experience more than 1 unit of time for each unit of time that passes on earth, an effect that is slightly, but not completely, countered by their increased velocity relative to the surface of the earth)
@@portobellomushroom5764 That's exactly what I'm referring to. I was 25S.
@@Hunterm10101I don’t think that’s crystals though. I think that’s vibration of individual atoms.
@scriptorpaulina It doesn't work except with crystals. And each crystal has a very specific frequency that it vibrates at when you pass an electric current through, that never changes. That's what we use to keep time for everything. That's how GPS works.
@@Hunterm10101 incorrect. What I learned in Hartle’s Gen Rel textbook is confirmed-they are run using cesium vapor and microwave lasers, not crystals.
I enjoy the effect of a random hand, handing off props.
Thing has been out of work since they wrapped the last episode of 'Wednesday'
I think that's a real hand but i cant tell lmfao 😂
I've been enjoying SciShow for a couple of years now. This has been one of the most engaging presentations, and the set design (green screen, I trust) was delightful! I hope we get to see more with this energy. Either way, I'm not going anywhere. You folks rock! (see what I did there?)
Office Desk Savannah? This feels so new and educational and stuff! I like it!
Whenever I see Savannah Geary on SciShow, I just know it will be good. Did not disappoint.
I went to college (and took a geology/rocks-for-jocks class) in Maine, where tourmaline is the state mineral! It's pretty abundant there, and we spent a long time talking about all the cool properties of tourmaline, along with how pretty all the varieties are. So cool to see SciShow talking about it!
Really, bone is piezoelectric!! Cool!!
Honestly that would make some death scenes in movies a lot funnier.
That's why when you give your desk the Knee of Justice™ you feel lightning at the point of impact.
Maybe that's how the ancient cavemen lit their campfires?
@@mysticgoddess9692 now we all know you have herpes

I have a lot of tourmaline in my rock collection. One, which I found at a mine, is a pala pink tourmaline and I had someone cut it. Love how it looks
You didn't have to include it but I am so very glad for the basic fire safety segment about clothing and hair! I have a horror story from my high school chemistry class about my teacher with her long, unrestrained hair striking a match (thankfully the matches were terrible and the match broke, although the adrenaline rush in that moment was very real)
The new set designs are really cool!
I've always loved tourmaline, not just for the colors but those shaft shaped crystals are just so cool to me. I was really surprised to learn you WEREN'T talking about quartz initially because the very first thing I thought when I saw the video title was "hey! quartz! piezoelectricity!" So that was really cool to learn that tourmaline "did it first" in a way!! Colorful AND magical!! Crystal vibrations in science are so great
That’s so cool. I love rocks and crystals
Piezoelectricity is so cool. It's also what's used to make piezo pickups for electric acoustic guitar, or just electric guitars that want an "acoustic" sound they can switch on. It works by using the vibration of the string (or body, not 100% sure, might depend on type and placement) to generate the electricity. It's also used in contact microphones and electric drum pads. Disclaimer: Not a guitarist or electrician, so I could be off on details. I just find it fascinating.
i gotta say, i love the desk vids. feels comfy
The hand coming from under the table reminded me of an old kids tv show.
Do look into the triboluminescence of quartz. It is used in the foundations of skyscrapers combined with light sensors, because if the crystal breaks in the concrete it will flash in the total darkness of the foundation, it is then picked up by the sensor. Thus warning of eminent structural failure or at least a vulnerability.
WHOOP! TOURMALINE!
Love the hand-offs on the dice and the battery! What a great touch!
yay Savannah thumbnail :)) i'm always so happy to see them host! they're so cool .
I finally was able to subscribe to the Rock box, I've been refreshing the site all day!
for the price and the crumb they send you its so not at all worth it. you can get weight of these stones for the same price. unless you just want to collect the cardboard boxes theres no logical reason to spend that kind of money on almost nothing. just dont want to see others waste their money
@@jessicajaerosenbaum115 It's more about supporting the channel than getting your money's worth of physical product.
LOVE the production on this one. The presentation, set, script, sound, lights, edit, and all the the production design. Feels timeless 🫶
when she showed the picture of the silicon dioxide and explained it my mind went right to a d4 then she was handed one. I smiled with joy and My day is good. I am sure I am not the only one.
Always appreciate it when science communication involves safety precautions!
I am absolutely loving this new lab/office background you have!
Hey friend!!! Your set up looks amazing and I’m so happy to have watched you get to where you are today, keep up the good work!!!! 💜💜💜
I love learning about stuff like this!
Thank you 🙏
Good thing I’m a pyromaniac so I won’t be scared scared of doing this experiment.
+1 Being a pyro -1 No reference to Def Leppard !
Aside from the fascinating information, I admire your shirt! Thanks for the video, Savannah 😊
I like how homey this set looks like
A Late Ex of mine told me Tourmaline was his favorite Crystal. He always had very well educated opinions on things and watching this has made me appreciate him even that much more. (if it was possible) 😢❤
"Don't want you to set your house on fire" SciShow with the real hot takes
Love Savannah's energy in this video, relaxed and convenient
I like this style of video!!! 💚
you know i'm mildly sad that you guys didn't name the rock subscription the "awesome rocks club"
I'm Unsuur how to feel about these rocks. (OK, who here has played My Time at Sandrock besides me?)
This is my comfort channel- everyone is always so happy! It makes me feel good right before bed
Thank you for this _tour_ of tourmaline 😎 ...I'll see myself out 😅
I'm familiar with piezoelectric gadgets but never heard of pyroelectricity! Thanks!
You and the bizzare beast lady are my favorite hosts in these shows. Thanks for showing us science!
I was expecting Quartz but I'm glad it wasn't. It's something I didn't know so it gladdens me
i like this look so much betted than the green screen
I love the look of the new set!!!
I really like this set and I want to do a bit of that in my office.
Is this the best scishow episode ever?
Well done
4:39 Hand? More Adams Family references please!😂
Boogie woogie woogie
Youre my dad?
@@pbgv399 your mom and I laughed
There are a couple of tourmaline mines near me in San Diego County 👍👍
Several of the specimens I have are from there. You used to be able to go out there after a hard rain and rockhound the gullies to find material that had washed down but I don't know how close you can get anymore. This was decades ago.
Went there! Oceanview mine in Pala California is awesome!
Glad to see Thing from the Addams Family has found a new job!
I need a lot more data on the "crystal changes its shape if you put electricity through it" thing. That has some potential for some crazy spec bio and or world building. Is there a special term for that I can look up?
That would be the inverse piezoelectric effect. Inverse because the electricity is being applied to produce deformation instead of the other way around. The beeps you hear from electronic devices often come from a small component that utilizes this effect.
Cirtceleozeip (i.e reverse Piezoelectric)
just find any standard introductory materials science textbook. we're talking about extremely minute deformations in the crystalline structure though, that doesn't deform enough to break atomic bonds.
Love my tourmaline gems in every color 💎
Tourmaline has always been my favorite
Awwwwesome jacket! Oh and look it matches your little bottles of um.. stuff! Cool😇.
you’re shirt is amazing
love that earthy magic✨
Ahh my favorite microphone is made with these
Cool experiment 😎🧪
I wonder if this where the whole new age crystal energy thing came from
Safe. I love the safety in this video.
great thumbnail, great video
Who's the magic hand under the table?
@0:24....🎶Boogie woogie, woogie🎶
Hi Savannah! SciShow rocks? No, *you* rock!
Heh. Whatever you do, don’t tell the healing crystal folks about this.
One of those charlatans sold me a piezoelectric crystal that didn't have the properties advertised. I went to return it for a refund because it was free of charge.
I was just thinking about lcd screens today at work and how they changed a lot the electronics we have. Also i like her outfit
It's not always true that materials expand when heated or shrink when cooled. Water is most dense at 4 C, and is the reason ice floats.
The desk setting is a lot easier on the eyes than the blue screen
Rock out SciShow!
THIS IS SO COOL Yet I am watching this 6 hours after release and the Rocks Box for this month is already sold out! 😫
I like how her jacket totally fit the subject matter :-)
Ngl, when I saw the title I was like “oh, it’s gonna be about quartz and piezoelectricity”….. so I was partly right lol. I’d never heard of this phenomenon before!
I’m a crystal collector and I’ve been after watermelon tourmaline for a while. It’s so cool- but expensive. I didn’t know this about tourmaline!
Aaahhhhh tourmaline, my favorite gem! So versatile, so beautiful, so scientifically interesting! Who wants stupid old carbon when you can have this! Also, just to mention it, tourmaline can also demonstrate chatoyance, i.e. they can show a cats eye or star if they're cut correctly. I have a black cats eye tourmaline ring that's magnificent. The watermelon variety also appears in 'reverse' with the green in the middle, and also in pink and blue.
I don't know who picked Savannah's outfit, but it's perfect for a tourmaline video.
This was a great video but now I want to hear about those piezoelectric bones.
XD I feel like I was hearing the voice of the scishow legal team during the explanation of the demo.
"and the answer is, wait for it,..." I love when they make me wait for it. Tease me with that knowledge baby. You naughty nerd.
Sci show does not want to set your house on fire
I did have to search if the Curie's you talked about were Marie Curie's family, which is awesome cause I think this is the first time in a while that I've known the woman more than the men in the family.
Maybe she's born with it. Maybe it's tourmaline.
I like how you just passed right by the bones statment.
One would imagine that Pierre Curie died from radiation induced cancer. In fact he was killed by a horse-drawn carriage in Rue Dauphine on the 19th April 1906. Age 46.
Ruby as well for lasers.
Wow! SciShow cares about my house way more than other channels! Most of them are more like "Don't do this at home **Wink**." :-D
the hand 😮
Its a naturally occurring meta-material. And to think we're starting to really get into areas of study for making similarly complex material latices of atoms for unique effects that may very well change society several times over.
I'm delivering a set of tourmaline earrings today, coincidentally
"you probably dont think about gemstones" I have not watched the video but immediately im thinking about quartz crystals that provide stable clocks
You are an absolute gem. 😉
Quartz: I have been beaten, boiled to death, and abused! STOP! *Zaps* Tourmaline: ENOUGH IS ENOUGH! *Bzzt* Bones: first time?
Could you use an uncut piece of tourmaline for this?
Kudos to the disembodied hand 😂
So this is why Gem-Knight tourmaline is thunder type?!?!
Y'know, i was expecting this to be a Roblox or a mobile app character. Was not expecting Yu-Gi-Oh at all. Didn't even know they had typings.
Radioactive diamonds ❤😂? Gonna get some for my niece!
