Exploding Glass: Rupert's Drop - Museum of Glass

'rear admiral'

[divisorplot]

Nice name for a luxury liner 'Prince Rubert'.

[mwestcs]

This looks shopped, I can tell by some of the atoms and seeing quite a few shops in my time.

[Fuffzehn]

@mwestcs Yes and now check the official Wikipedia article about this and see it is not faked. Pure Physics... just not what most people would intentionally think when seeing this.

[Hercolicious]

The Wadsworth Constant applies.

[NoobOfLore]

That's right, ladies and gentlemen. With nothing more than molten glass and ice water, you too can counterfeit cocaine!

[Spearixx]

imagine that in the shape of a bullet being shot into you.

[TheRevolutionstarter]

Amazing

[yudanielk]

I can almost here the Blendtec guy in the background at the end... "Don't breathe this". lol.

[JokimciusGoras]

visas reikalas uodegoje.

[stiklas]

@JokimciusGoras tu teisus , įmetus karštą stiklą į vandienį susidarė mikro įtempimai ir jie pasiliko stikle nes lašas per mažas kad išsprgtų savaime :) vėliau visas reikalas uodegoje , jis tik nulaužė uodegėlę ir to užteko kad išlaisvintų itempimą..

[RiotousGhost]

But, Will It Blend?!?!

[50srefugee]

The best and clearest of the PRD videos I've seen. I've known about these things for decades, but I've never actually seen one break before.

[TigersPrettyBunny]

wow 0.0

[bloodjake12]

IF you breathe that in you get super powers

[Alisterhenry]

Subsequently becoming Glass Man

[SiddTheFrickingNayak]

@bloodjake12 *Breaths that in and simply dies* Innocent Bypasser: LOL Look at that poser, he thinks he's glass man!

[trailkeeper]

Its a good way to make powdered glass, maby for sandpaper or something, or remelting.

[riedude]

my town is named Princ Rupert.

[denelson83]

@riedude In BC?

[aramilalpha]

That'd be an awesome and easy way to create frit. :D

[JasonVz]

My names Rupert and i'm gonna steal your dinner money

[nigelcje]

HAHA THAT'S SO RANDOM IT'S HILARIOUS

[squimball]

So what would happen if you cooled it in say, liquid nitrogen? A super Rupert's Drop, or a deadly explosion maybe??

[nigelcje]

don't think so... probably it'd be weaker than an ordinary rupert's drop because then the insides would cool almost as fast as the outsides.

[squimball]

I want to see that explode at 3000FPS!

[dylan2106]

second!

[terongorefiend15]

Third!

[LegendSaber]

Fourth!

[frizspin175]

fifth!

Eleventh (Tenth really, because hickler13 counts like a retard)

[AlaskanGenius]

seventeen ( because I count like a retard)

[SirMildredPierce]

Will it Blend????

[SoManyDumbPeople]

lol! The ending's just the same!

[SasukeDracoNick]

Those are so awesome......

[FilmPA]

Why did it explode......?!!?!?!?!?!?

[Goatmon]

A Prince Rupert's Drop is so strong that you can hammer on one end without causing a crack, but watch out for the other end—it breaks easily and causes the whole thing to explode!

[djxjam2daz]

your comment explains nothing...

[Faeilli]

If the tail breaks, the surface tension is released and the surface tension holds it together? I dunno, they have anothervideo on it 0_0

[aramilalpha]

What occurs is that the exterior of the glass cools quickly whereas the interior of the glass cools more slowly. When the interior cools it pulls on the top of the drop so that it becomes more compressed which adds strength to the glass, however, this cooling also has the complete opposite effect on the tail. SO when the tail breaks it causes the entire glass to fracture at more than 4000 mph, hence the explosion. Its all about stresses and tensions in the structure of the glass itself.

[nbrege]

Jeez, I could've copied wikipedia too.

[aramilalpha]

I suppose I could have as well. But seeing as no one else was answering the question I figured, being an experienced gaffer, I would explain the phenomenon.

[happypotroast]

???how did it do that???

[myopicprude]

So cool. I'd love to see one of those up close.

[xstatik3]

Awesome stuff, thanks for posting

[drumhighguy]

wow what is that!? why does it explode like that!?

[anzhelik]

Rupert's drops are one of the very first proximitys to tempered glass, when the molted glass hits the water, the outer layer cools too quickly, causing the still hot inner still molted glass to shrink as it starts to cool down, it pulls the now hard surface and creates a weird tension which causes the structure to spread energy of the impact of a hammer so it won't break if hit on the bulb,

[anzhelik]

But, when the weak side, the tail, is broken, thousands of microfisures spread through the bubble releasing the tension, hence, it explodes ;) hope it helps

[tonton423]

sweet buddy thanks! you just saved me 3 minutes on google lol

[MarJo138]

would the same happen with borosilicate?

[Nixta91]

Obviously not
