I came here expecting to see glass spawn from fire and sand. I'm not amused.
Nathaniel Pek Meng same
Did the word "sand" even occur in this video
Nope
nope
Nope... but now I know glass breaks when it falls or bends.
lets burn
note to self....read comments before wasting time waiting for subject of video title to come along
+Martin Walters It actually wasn't a waste of time, the video describes how tempering of glass works.
Where is the making of glass
I came here for sand + fire and left disappointed.
me to
me three
me four
i like bananas
me too
Fire + Sand = Glass!..................Not in this video
This video is about the Prince Rupert's Drop, not how to make glass using sand and fire. Very misleading title.
2:29 blew my mind
seriously what the duck?1?!?!
What the fuuuuuuuuck never seen such a beautiful hammer!
ROCKaholic are you from the US?
Dreel Loxter lol yeah why?
Dreel Loxter Ignorant douchebag confirmed.
Glass blowing has always amazed me.
Where's the effing sand? Is it even mentioned?
+Mition animation Lol...
relax
I just spent 5 minutes of my life learning about glass.
Wait wait, hold on. People make bottles out of *glass* now?
For 120 years now..
+dandeentremont i tought glass is ceramic hmm is taht true
yeah like coca cola mountain dew and more!
Ceramic is made from clay, glaze from glass, melted sand.
I dont mean to be offtopic but does someone know of a tool to log back into an Instagram account?
I was dumb forgot my account password. I would appreciate any tips you can offer me!
People are disliking because they are so used to action videos, like they can't comprehend a video could have a totally relevant title that sounds exciting without being an action video. It's an educational video! Don't dislike just because you are too lazy to enjoy the science.
common Glass is composed of about 75% silica (SiO2) plus sodium oxide (Na2O) from soda ash, lime (CaO), and several minor additives. The most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz.
1:45 R.I.P Glass jar :(
What about molten glass dropped in liquid nitrogen? That would be a tough one to break.
I cant get liquid nitrogen were I live, or at least easily.
It would implode probably due to the rapid temperature/pressure change. Even in RTemp water it's possible. LN is near absolute zero. That's a long, fast fall.

You will NEED a Dewar, You will have to get one of them if you want to take any home.
Awesome idea, I was thinking of something liquid and cold.
I thought salty ice water, Maybe both should done. Though im sure someone has ?
***** Liquid Nitrogen is not near ABSOLUTE ZERO at all. Absolute zero? The point of basically no movement.
Igor K Thats what I meant. but I heard that it's impossible. So 99.999999%
Well that is 5 minutes I won't be getting back...
People are getting pissed. Change the title.
Great video. My fish liked it also.
i was far more fascinated with this than i had initially thought i'd be! very nice.
why does everyone make that pumpkin?
well its three in the morning and i dident come here for sleep but it damn well gave me it
Really interesting! Maybe the best MITK12 Video so far.
Dude didn't even say "sand". Masterful trolling, MITK12Videos. Well done.
"I don't like sand, it's coarse, dry and gets everywhere"-Anakin Skywalker
Anakin when Rey burried his lightsaber in sand: "I HATE YOU!"
That's the longest Prince Rupert's drop I've seen anyone make. Very cool!
the fuck this is not what I came for
Not what I expected but cool!
Well explained, with a nicely modulated voice and a lovely accent
y'all are like "Where is the sand?"
It turned into glass dum dums
at 4:20 you show a Prince Rupert Drop under polarized light
the "bubbles" are shown with dark lines around them.
My question for MIT is : Are those really bubbles or are they under vacuum?
basically you have a molten mass of glass that should be fined out (having no bubbles).
when dropped in water the PRD contracts as said from the center that remains
somewhat soft.
Many of the bubbles in PRD are weird shapes pointed and flatish ,no where are they roundish as most bubbles in glass or other fluids.
So picture this ;;the "bubbles" are formed like putting you hands together palm to palm
and then moving you knuckles away from each other making a hole between your palms.
Wouldn't this cause a vacuum and not create bubbles.?
You can also get "bubbles" to form by gathering up some glass ,, blocking the form
to make a round ball then blast one side with compressed air
as the glass rapidly cools you can watch the voids form and get larger as you apply
more air.
i speak from 35 years of glass batching and glass manufacturing experience.
I once knew how this worked.
After watching this video I forgot everything.
Glass is amazing.
just learned about glass. feeling good
Chances are it will be too late by the time you see this but just in case:
If you came because of the title, the video begins at 4:59 and ends at 4:59. Considering that no where in the video does it relate to the title, the video never happened.
Its just a title people
Its the content that is important
Not the title
Cool, so lets strip the titles from all youtube videos since they're unimportant and a waste of screen space then. Makes total sense. /s
Reading the comments section leaves me no hope for humanity.
P.S. Great lecture on materials science/continuum mechanics. :D
Well duhh... haven't you played minecraft?
Sterling Archer yeah that's why I came here lol
the end of the glass drop is extremely strong *hits it with a hammer like with a pillow* fucking apply your whole force to it and you can see its very weak
Thank you for explaining glass to me
Not what I was expecting, but it was well done.
2:32 Mind blown
8 years later on my recommended, cheers youtube
1:54 right when the shards flew, i felt something hit my hand and slide along my arm, like a shard of glass had flown at me, except it was kinda soft and didn't hurt, and after THERE WAS NOTHING THAT COULD'VE HIT ME!!!!!!!!!!!!!!!!! that's freaking crazy awesome
!looks at title! MIND. BLOWN.
ductil means the capability to transform a metal into smaller and shorter wires
I will never lick my glasses EVER AGAIN
Wow thanks for showing me how to make glass
Wow WHO KNEW
SUCH AMAZING
OH MY GOOD
WOOW
(Sarcastic)
You didn't explain how thin fibers of glass can be extremely flexible, that glass is now becoming a standard everywhere for moving data at light speeds, or that glass is used as a structure material and to provide structural support.
Fire =15%
Sand = Sry, Wrong title.
Glass = 85 %
And sadly they didn't add fire to the sand nor sand to the fire and wtf where is the sand.
It's in the glass. 😏
Does the glass only bend with heat or are there some materials
So will go to the beach, collect some sand, go back home, put it on a pan, on the stove to provide fire "heat" then will have a circled shape glass !
Peppa big
This seems so much more interesting then electrical engineering........
+sanosukeX2 Na- everything seems equally interesting when explained by a good teacher!
so why the thin end is needed? why all glass objects aren't just cooled down rapidly in water? Should get the same effect only without fragile tail.
Very impressive
i hate it when people say glass is brittle ... a glass wall would be more solid than bricks but noone makes windows just as thick as walls
Compression and Tension theory is back to front i believe.
I like the glass video.
Lol im watching this on my phone which has a big crack in it
good job
Are the bubbles left in the glass vacuum?
You helped me a lot at a school project
2:11-Looks like lava to me.
Why don't you post a video that tells us how long to put it in
Wow this is cool
_chaaannngeeee the titleeee!!_
this is very informative
put sand on the top of the furnace and coal at bottom to make glass block!
I was looking for a Simple English explanation on how glass is made. But instead I found #Science Class.
well improve your english
For reference, they don't thermally temper glass in smartphones, that would be a bad idea. It is chemically strengthened using ion-strengthening.
Press 5~
& your reaction goes like this :O
I was so excited to watch this video, And then I get B-U-L-L-S-H-I-T.
thank you
those glass drops are pretty much just tadpoles
It's not ductility. Ductility is the ability to be drawn into a wire. Malleability is proper as it is the ability to formed into a shape without deformation or damage.
"What's" not ductility? Malleability is supposed to be smacked into shape-changes... No?
If you don't know...... ASK!!!!
Would really love to find people who can work with me on my land to start making glass because it's full of sand
Amazing science
2:32 lol how?
what smartphone is the one at 0:58 ?
Ok,that's we're the glass made. Hehe
The stuff from around 2:00 about the Prince Rupert's Drop was WHOA amazing! but yes, title is misleading and while I wouldn't go so far as to call someone a "cunt" as other comments have, we really expected to see actual common SAND being refined and doped into consumer glass. (The info is Google-able, you wouldn't be blowing up any deep trade secrets)
I tie all my glass items, with Abok knot #1142.
This guy sounds like my science teacher
good to know
This was just an educational video about glass, I didn't see any sand
I came here because I always wondered why when I put sand in Minecraft, I get glass LOL. now I know this XD
Am I the only one that has noticed this factory is making glass for hookah's and bongs?
Fire + sand ≠ Glass.
Fire + sand = Fused Quartz
I feel...
Smart now
wrong glass breaks because it is non crystalline non repeating structure and metals are bonded throughout the whole structure that's why you can bend them
I think Everyone knows what happens when sand is heated enough so don't make a video where the title looks like your very surprised about it.
Won't cooling a glass faster produce a HIGHER density? (since the same no. of molecules are trapped inside a smaller area?)
It might break cuz it contracts fast
+toopan panpan Oh ok. Thanks.
if i had a phone this old i'll break it on purpose
It reminds me of Firestar and Sandstorm
Make a prince rupert's drop without the tail.
what the actual fuck I came for!! The picture of the video is turning sand to glass from a microscope and like the fuck this
Yeah, this showed me what I can't to see. 😒
I love me some glass every morning
what samsung is that
Where was the sand part?
