- Crushing Prince Rupert Drops !!
edit 15/05/16 : This experiment will be done again ! This time with much larger drops and the tail out of harms way ! check our Facebook page to see a picture of the drops we just made for the 2nd experiment !!
This video was requested by MANY MANY people, so here you go !!
First of all, we were amazed how strong these drops were !
With the 1st drop, we started with a piece of wood to see if the drop would be pressed in it, and YES.... the drop was entirely pressed in the piece of wood without any problem.
Then we took the same drop and pressed it between 2 steel plates. This destroyed the drop at +-20 Bar.
Each Bar is 214kg, so the drop took aprox 4.2Tons before bursting .... Pretty nice tough ...
The 2nd and 3th drop were put on a piece of lead (softer metal then steel), to see if it would dent the lead...
The drop went into the lead pretty deep before it burst, but you can clearly see how deep it went before it burst.
There was allot of cutting done in the video because it took several minutes to remove the glass from those holes in the lead....
Result : These drops are very strong !!
To make a hole in lead with that size requires pretty much force....
Thanks for watching !!
Put your ideas in the comments what you want to see pressed !
Note :
Also visit the "Hydraulic Press Channel" from Finland with their awesome Hydraulic Press Channel !!!

Can we get another one with rupert drops, but where the tail is outside the crush radius?
+Patrick Winter Agreed. I felt like most of the time the Rupert Drops were only breaking because of the tail section snapping. The tail should should have been left out of the crush radius.
+thewhoopimen what would be the difference?
+Gerardo Salas The tail is the weakpoint of a Prince Rupert drop. A Prince Rupert Drop is almost indestructible as long as the the tail does not snap. It has very contradictory properties, able to take great stress on the drop, but will explode at the slightest damage to the tail. As long as we see that the hydraulic press only working on the drop and not the tail, we can better gauge the compressive properties that the drop can withstand. If you see it in their lead plate demonstration in the video, the drop actually presses through lead first safely, but shatters when the tail touches the lead.
theres a great one done by warped perception check it out
Agreed
I was expecting that when crushed, Prince Rupert's Drop would break down the very fabric of space and time and create the wormhole leading to another universe
+Guten That wormhole did form in the video, but it got crushed with the drop ;p
Same
Mandela effect
the mandela effect is a fabricated lie to feed the feeble.
Guten
the head is not infinitely strong since the tail is not infinitely weak.
If the tail was infinitely weak it would not even sustain the passing of time through it.
press Hillary Clinton
+Jack Mcslay you can't press her, she'll just dodge it and put someone else there while saying "I have no idea what you're talking about".
When it got embedded in that block of wood and that tail snapped off, that drop turned into a live grenade.
What do u mean
+Dudeg6 when the tail is damaged the entire drop just "explodes" or disintegrates
+Gray Winchester yea that's true
+Dudeg6 Search for: smartereveryday prince ruperts drop, youll understand what he means
How did the tail brake off without grenadine the rest of the drop?
that's how their supposed to work, drop is nearly indestructible but the tail braking causes the whole thing to explode.
YOU SHOULDN'T PRESS THE TAIL
ikr
when are you going to release the new video with the tail out of harms way?
The explosion only happened because the tail was damaged
+Joe Crick Yep that's what we also think. They would not break if the tail wasn't damaged imho
+PressTube you should do something like a whole chicken...not alive of course.. in your press tube..
+PressTube Should have tried to put it on the edge with the tail outside the danger zone of the press
+2tts Would not work, as soon as the drop is pressed halfway into the lead, the tail will also snap.
+PressTube don't put dead beings between that press, you'll get so much hate
See if your press can crush one of those old nokia phones.
Their indestructable. :)
*they're
nitroman365
Sorry, my english is not good.
+nitroman365 wut ?
+television and cheese cool.
nitroman365 whuat ?
Please press my ex
mine too we should tie them together
Mine Too , Mine Too ... 3 At Once
+Kufre Udobong Mine won't press. Her cold heart is too hard. :/
cubeyuk Damn LMAO
+Kufre Udobong the press will be damaged
If you hang the tail out of the press the result changes dramatically. After all any portion of the tail is a weak point in the structure.
+PressTube please consider this one.
This wasn't done right. you need to protect the tail and smash the drop. the drop didn't shatter because you smashed it. it shattered because you failed to protect the tail by putting the whole thing under the press and allowing the press to kill the drop via the tail.
+Joshua Szanto Yeah makes you wonder if they knew how these drops work or not...
As I said before, this channel finds way more interesting things to crush than hpc :)
+Princess Rainbow Dash
Both channels have their pro's and con's.
I for one, enjoy stuff being crushed no matter which channel does it, hell, if I had a hydraulic press I would do the same.
I would love to see this again but this time protecting the tail, I'm sure you will be able to press them straight into the lead without breaking them. On the first one you were very lucky the breakage of the tail didn't created a chain reaction and shattered the whole drop, I'm sure you can get one on lead too.
Prince ruperts drops:you cant break me
Nokia:Fight Me!
Had to look it up too: Prince Rupert's Drops (also known as Dutch tears) are glass objects created by dripping molten glass into cold water. The glass cools into a tadpole-shaped droplet with a long, thin tail.
I'm pretty sure that, if the drop is made properly, it's meant to shatter when you break the tail due to the internal stresses. What you have here is a glob of glass.
That is what I thought as well. Someone here doesn't understand how a prince rubert's drop works.
+Justin Grazulis Try to put one under a hydraulic press without exposing the tail to pressure. It's impossible
That's not the argument. The drop already has a broken tail therefore it should already have shattered - therefore it's not a Roberts drop. It's just a drippy bit of glass
Please redo the Prince Rupert drops with the tails outside of the crush radius. This video was ruined by you overlooking this major detail. The drops are only 'near indestructable' when the tail isn't snapped off or removed.
+thewhoopimen Yep we are going to do that ;)
+thewhoopimen you tell em brother man
+PressTube. I was thinking the same about the tail, I'm glad to hear a redo in the future.
Lol here I am thinking it's gonna be indestructible
What an interesting effect, it seems when the drop itself is under pressure, breaking the tails do not cause the usual chain reaction. I wonder why that is.
I heard that when you pressurize ice it momentarily turns into water like during ice skating. But it immediately turns back once pressure is removed. Try pressurizing a huge block of ice. Also if there is a way of making an airtight system, I wonder if you could make liquid air by pressurizing it. Also could you try pressuring an egg in the vertical position? Science tells us it's indestructible.
Yeah if you use your hands and even then if you squeeze hard enough it will break
It technically is , however it wud only be indestructible under perfect conditions , any imperfections in the material providing the force and any imperfections in the egg shell wud cause it to break easily with said force
I'm personally a fan of the ice idea. Using a thermal camera on that would also be pretty neat.
Whoa! I didn't even watch the video yet and I'm very interested. I would have never thought of this.
really shows you how strong these are, and how much internal forces they have built up
I can't wait for the grenade.
+RPKVids Will be online at 15.00h local time (Belgium). On our Facebook page 1 hour earlier ;)
+PressTube that is what I was looking for awesome video I was thinking it would hold up a little better . how much pressure do u think it had on it before it exploded? ????
+Mike Wakefield look in the description
Who else has no idea wtf a Rupert drop is
Me lol
👋 ditto
It is a piece of glass that is cooled very rapidly (usually by dripping some molten glass into some water.) This rapid cooling creates a very hard and very brittle droplet of glass. It also exhibits the property of extreme instability when damaged, such that even snapping the very thin tail of the drop will cause the whole thing to explode.
me
I just googled it - quite amazing little things. They are small pieces of hot glass dropped in cold water. The outside cools down, while the inside stays hot for a period of time. This causes a lot of stress and different forces within the glass. It can reportedly withstand a hammer strike, but if that tail is even slightly damaged, the drop will explode, causing glass splinters to fly around in a bout 1.5 km/s.
This needs to be done again with the new high speed camera you guys got!
You should retry pressing a Prince Rupert Drops against a Circular Saw Blade. They are usually made of Cemented carbide. I.e tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) . Or press against a diamond Circular Saw Blade. Then it would be interesting to see what happens.
If this will be redone, then leave te tail of the Prince Rupert Drop outside of the press so it can't be damaged. The tail is it's only weak point. For more information watch Dustin from SmarterEveryDay explain about the Prince Rupert Drop.
+David Andersson
Something with a high sharpness could cause more pressure to be exerted between atoms, so that is a good idea.
Prince Rupert's Drops (also known as Dutch tears[1]) are glass objects created by dripping molten glass into cold water. The glass cools into a tadpole-shaped droplet with a long, thin tail. The water rapidly cools the molten glass on the outside of the drop, while the inner portion of the drop remains significantly hotter. When the glass on the inside eventually cools, it contracts inside the already-solid outer part. This contraction sets up very large compressive stresses on the surface, while the core of the drop is in a state of tensile stress. It is a kind of toughened glass.
The very high residual stress within the drop gives rise to counter-intuitive properties, such as the ability to withstand a blow from a hammer on the bulbous end without breaking, but experiencing explosive disintegration if the tail end is even slightly damaged.
what are they used for?
It is pretty interesting to watch all those crushed in the press nice.
The other guy's press seems stronger. He can keep it on to flatten almost anything to paper thin.
+rock962000 and now he must deal with it....
I find these videos oddly relaxing to watch as I try to fall asleep. This channel has been keeping my sleep schedule intact over the past couple of days.
crush some peanuts for some peanut butter
i once was at a glas blowing factory and they where nice enough to make some for me. They where even bigger than yours and it was really weird letting them ex/implode in your hand (i had a security glove though)
What am I doing with my life lol
Your intro is even louder than HPC's!
It broke because once the drop was pushed down far enough in the lead, pressure was put on the tail which made it break. It is very easy to break those drops if you grab the very tip and break it.
try with a hand
+Joshua hydraulic press channel did it with ballistic gel.
You can already find videos on LiveLeak.com of hydraulic press accidents and pictures of the after math on google images
i mean breaking it in a bag with yo hants
ReddyWOW prince rupert drops are glass. I dont think its possible
a guy did it, the hand outside and the drop inside a bag
Protect the tail during the test's, the drop will shatter if cracked in any way. Also the first test could have had much more pressure applied if the drop didn't roll and scratch when the pressure was increasing. Any scratch or defect in the surface of the drop will cause it to shatter also.
Great idea for the Prince Rupert's drop!
This channels growing so quick
Wow, that's a big holes
While the head of the drop can be hit with a hammer without breaking, when any portion of the tail is damaged, the large amount of potential energy stored in the internal structure is released, causing fractures to propagate through the glass toward the head at very high speeds which break the entire structure into flakes and powder.
You gotta keep the tail safe, only the actual drop is "stronger than steel". once the tail is broken, the compressed forces stored inside the glass are released in an explosive manner
so you like to inhale fine glass powder ánd lead dust at the same time.?!
This one is much better than the other one I saw.
So, where do we see the second version with longer drops? There is no link and it's not on your channel.
How do you get the tails off those drops? It seems that it only sometimes explodes when you do that?
What I would like to know is whether or not the point of break for the drop is when the metal touches the stem. I've heard/read that the weakness in the drop is the stem. Even slow-mo is too fast for my eyes. Does the bead burst when the outside force touches it? What can the drop itself withstand without any pressure on the stem? Why does this happen?
you have to do this again but somehow find a way to keep the tail from being crushed maybe put it on the edge
+FrankieBeans Yes quite!
is there a way you can do one with a car tire ?
Can someone explain how the press works and how it has that much force?
+kim Dierichsen wtf is google?
kim Dierichsen i'm bing. how are you?
It uses science
Transferring power through hydraulics has an advantage, and is that by sacrificing distance (the distance the press moves) you can generate substantially more force. You do this by having two presses, a very thin one that moves a long distance and a very thick one that moves a short distance. If you move the thin one, say, 10cms, the big one will move only 1cm but with 10 times the strenght. It's analogous to how a lever works.
The short and easy answer is THICK OIL, it doesn't compress, so the machine can "spit out" tiny amounts of oil behind the crushing head over and over until it builds up enough force to crush whatever you need.
(Just like inflating a balloon, it's much easier to inflate with a bunch of small breaths, instead of one giant one.)
How did you make this drop? Because the type of glass and the shape matter when making drops. If you want some strong ones, get a glass rod and heat it from a 45° angle upwards towards the bottom.
wow this one really grabbed the viewers attention I'm so glad you were able got the drops so quickly from when we talked about you trying to get these, thanks for making this video!!!!
You should crush a Prince Albert next.
NICE
This isnt fair for the drops eh. If you want to do this in the right way you must press only the drop without the tail...the tail is just normal glass but if it breaks the pulling inward forces all get leaked and the drop blows up on its own...
So you should repeat all of this because in all of the the tail is what breaks the drop.
+Vialli J (VialliRM) did you read the description? ;) check it out
+PressTube Oh. Haha
My bad.
+PressTube Way to fuck it up though.
Is this the way to make sugar?
Lol thats amazing ^^ They are tough af
I'd like to see a stack of pennies or nickles in there. Like 20 of them. I'd like to know if they would be pressed into one big sheet or would they be able to be separated? I guess one big sheet, but i'd still like to see it.
i read a stack of pennies as a stack of penises... Good god.
Yeah, that would be very different...
Are these real Prince Rupert Drops or just normal glass shaped like one seeing as they didn't explode when the tail got broken off?
CRUSH THE BOOK!!!!!!!!!
You need a sponsor who can supply you with some LED lights to illuminate the thing being crushed.
Interesting to see this drop sustain pressure.
im new to prince rupert drops... what are those?
Pince Rupert's Drop is such a remarkable structure! Great idea for use with the press!
What is it tho
+Seth Schneider glass that is heated until it drops into cold water. they are stronger than steel when used correctly.
seriously? damn
it appears as if the tail of the drop gets pressed which will cause it to break sooner. just snapping the tail releases all the stored compression.
I don't think you crushed the actual drop.
You could try with sheets of glass , i recomend 3 mm thick 3 of 4 layers, of little squares, and make different samples each with a different adhesive, the thing is that I tried it with a bench vice and any adhesive between the sheets of glass and I reached a point in which the glass was all broken, but still was in place, it showed an impressive resistance, and then it started to make more and more breaking noises and then it exploded :) , im pretty shure thar you could stamp a lead ingot with that.
I've got a suggestion for your next press! How about a brake pad from a vehicle, or one of it's spark plugs. Why not both?
Also, compressed, canned air, like the dusters.
wouldn't a prince ruperts drop shatter the moment the stem broke? the stem on the drop broke during the wood but the drop didn't?
how can this channel grow so fast
+Manuel Eckstein It's a generic "big channel with a unique thing", there is no way but up to 1.2M subs.
Okay! Now try to press a granite stone! =P
Holy shit the drop actually made the press shift before it cracked it, damn... Maybe because it's round, Now I wanna see a comparison with another round object such as a ball bearing or the likes and see if the press shifts like that, anyone have a link to the press shifting on any object of similar size? Maybe I just never noticed it shift until now, I've watched many
is it possible to do one of a skull or bone?
What exactly are prince Rupert drops I've never heard of then
Awesome vid that piece of glass is hard to break
Hi guys can you explain me what is a prince rupet drpos please ? I am not a native english speaker . Thanks !
The trouble is is that the press is breaking the tail. You can't break the tail - It shatters the whole thing.
If that was really the case then how did it not explode between the wood and the steel, the tail was broken there.
+Morru Qu'aan www.popsci.com/diy/article/2008-06/shattering-strongest-glass
Drew Layton First of all, yuck pop science second, this doesn't address my point pls watch the vid again, the tail was broken and it didn't explode.
+Morru Qu'aan Yeah, but PopSci had an adequate answer. No idea, maybe the pressure of the press was enough to keep it from going boom.
***** Who's being ignorant and how?
Which channel is better this one or hydraulic press?
what are those things for?
Prince ruperts drop are stronger than steel. It didn't get shattered when you hit it with hammer. But when you break the tail of it, the whole thing explodes. It's a fun experiment.
do this with slo mo guys
Press a giant gummy bear and soap bar!
What exactly are these little things?
Let's see you do a 30oz Yeti Tumblr
OH MY GOD I HAD THIS IN MIND THANK YOU
awesome the drops they had those on mythbuster crazy amount of strength and force to crush but if you shatter the surface tension its done
+zackery Fisher like a balloon
is possible to buy rupert drops?? where? thanks
What is that? Looks like an earing. Never heard of one before. Just glass?
yep. just dro
the secret of their strong is the tail, there is no tail there, so tension are not organiced to the back tail, otherwhise the resistance goes down.
Prince Rupert drop made out of liquid diamond, my dream lol.
Crush a Rupert-drop on something that has a space dug out of it for the tail to fit in so that the tail doesn't get crushed, and THEN see how much force it takes to crush its head.
can you try a human hand next?
What are theses drop things can any one tell me please
woah just uploaded
what is prince Rupert drop?
+Abishey Dean Heat up glass so it melts and drop a drop of it into cold water.
The thick bubble part is incredibly strong, due to surface area being under incredible tension. You can smash it hard as you want with a hammer and it won't break. However, if you cut the tail part of them all that tension goes and the whole thing explodes.
If you rewatch this video, you'll see they mostly pop and the tail part is pressed on and breaks.
You have to be sure the TAIL isnt in the way. The moment the tail of the drop snaps, the drop itself shatters.
Who ever came up with this ideas is a fucking genius
They should shatter immediately when you damage the tail, but these don't...
yeah, these aren't real Prince Ruperts drops.
Ender Skies The very first one had its tail broken off and was still mostly intact, instead of violently exploding.
+Tal Risin NOD RULES
It was a great idea to try it on diffrent surfaces!
press the lead itself
What are prince Rupert drops?
