[@Hiihtopipa]

You can shoot them with a bullet too

[@harrylane4]

I’m not surprised. They can shatter bullets.

[@sc4rydude277]

Now let's see paul allen's hydraulic press

[@swanihilator6748]

​@@harrylane4 Bullets are actually made of softer and therefore less durable materials than steel. This is so that they can spread over an area when they hit and penetrate a target, causing them to undergo more resistance and thus deliver more impact force rather than just going straight through. It's also to reduce frictional damage on the interior of the barrel it's being fired from.

[@WaRn00b85]

The interesting thing with Rupert's drops is if you damage the tail whatsoever, it literally explodes. I think with that large one, you can check it tilt towards the tail, and it might've placed the tail under more pressure at an angle on the tail, which caused the whole thing to explode. Had you kept the pressure only on the ball/teardrop section, I think it would've gone much higher.

[@i3017]

I agree on this. The biggest drop moved and the middle part touched the metal part of the press. This, likely, was the cause of it shattering too quickly. I was expecting they saw this and had a do-over of the biggest Rupert's drop. Cool video... but not a complete experiment.

[@AaronMittelmeier]

Yeah - It looked that way to me too. The irregular shape of the drop played a part, but it still looked like there was a frame where the wider part of the tail / base of the head might have touched.

If you mounted the drop with the tail part being horizontal, I would expect the final crushing force to be higher. Also, it kind of seems that you may have weakened the drop by applying force to the tail by the edge of the pad and we know what happens when you crush the tail.

This is actually incredibly dangerous without proper safety measures, even though neither of them were hit by the shards directly. You're likely to have lung problems later in life; even though they let the dust settle, there are still tons of microparticles in the air. The only way to safely sand or explode glass, is suspended in water. And if it's not in water, then run a misting spray of water in the room afterwards, for a decently long period of time. This is to weigh down the silicate particles in the air, and ensure that they are on the ground, rather than in your lungs. Best practice is to have a HEPA compliant air filtration system always running in rooms where this kind of crap happens, and change the filters after every aerosol-prone endeavor.

Doing it every day will absolutely cause immediate problems,but even one exposure can lead to issues not unlike asbestos exposure; years later, it's gonna crop up as a bad source of lung damage, and damage to any other parts of the body that any amount of it that may have made it past the lungs and into the blood. The people behind this channel have shown a repeated lack of care for finer safety details such as this, so I fully expect that the things they've exposed themselves to will likely bite back in a few years' time.

[@aaronm.3581]

@@kmemz Lol. You are a moron. Silicosis typically takes 10 or more years of exposure to develop. It's highly unlikely that these people will have any lung issues due to this one small exposure. It's not like asbestos, as you claimed. One small exposure is not known to be harmful. Quit making things up.

What is truly amazing is that this is very close to a point load. I would say the actual contact surface on side is less than 2 mm^2

[@baltazard133T]

The big drop shattered quickly because if you watch the video in slow motion you can see the tail was receiving pressure before the main part of the drop putting extreme lateral pressure on it causing it to shatter prematurely.

Hi: Two thoughts: 1) film this in the dark, I bet there is a big flash (triboluminescence) and 2) put some sausage in the path of the debris, like if you had a finger there (ouch !). Cheers, Mark * * *

[@maxoobbxxx8032]

Mark Beeunas I think there’s a visible flash when the 67 tons explodes the second drop. At the very top of the drop.

[@robbiehartstein7059]

[@colereed7411]

Good comment

[@medexamtoolsdotcom]

I doubt it. Glass is not quartz, there are impurities that ruin its piezoelectricity, after all, quartz is crystalline while glass is amorphous, and that right there is the problem. And triboluminescence is just visible electrical discharges and without the electrical potential generated by piezoelectricity, there is no triboluminescence. But it should be even worse for Prince Rupert's drops, because of the rapid cooling in their formation, it should be even more amorphous than regular glass, in other words even on the tiniest scales there should be no chance for any crystals to form.

[@MrJudeWanamaker]

Fucking interesting

[@daneg007]

the big one broke quickly because the tail was down and cracked first.

[@philsangster677]

I want to second this point. The drops are very fragile if you apply lateral pressure to the tail. It may withstand over 30 tons in the press but you could shatter it in a similar fashion using your bare hands if you just snap the tip of the tail off.

[@starsidehaze2410]

@@philsangster677 I wouldn't recommend doing that tho because you would get small glass shards everywhere

[@ajstman]

[@michaelolsakovsky]

Yes the tail got caught on the edge. They should redo this and position it properly

[@patferrish4601]

I was wondering if that was the case, watched the slow mo shot a few times trying to catch where the break starts but its so fast. Doesn't look like there was enough room to allow for the depression in the steel without the base of the tail making contact

[@MrHanowski]

It would be interesting to do hydraulic press strength comparisons between a piece of regular glass shaped like a Prince Rupert Drop, and an actual one. Maybe regular glass is just as hard/strong? I doubt it, but it would be a fun demonstration comparison.

[@MEMEBEAN6960]

Regular glass does not compare to the Price Rupert's Drop. The reason the drop is so hard is because of immense pressure from the inside, while the drop is hot the air inside of it is hot as well, once it starts to cool down it creates a vacuum on the inside which drags all the sides inwards.

[@MrHanowski]

@@MEMEBEAN6960 Vacuum has nothing to do with it. It's all about internal stresses in the glass created during the cooling process.

[@IsThisLossE]

@@MrHanowski vacuum is kind of right. glass shinks when it cools down, and the outside shrinks first before the inside does. then the inside pulls on the outside, making the outside extremely compressive and the inside extremely tensile

[@wh3596]

For the big one, you should point the tail end up. When the press started the piece orientation changed where the tail was being pressed.

[@curiousnerdkitteh]

I love how much fun this couple have crushing things, they're like big kids. You know we all wanted to be able to do something like this when we were little. Thankfully we have this channel!

[@sealpiercing8476]

Maybe you could make a stronger drop by cooling the glass in concentrated NaOH or KOH-- try to do a bit of chemical toughening as it cools like they do with gorilla glass.

[@HydraulicPressChannel]

Hey that's great idea!

[@sealpiercing8476]

It looks like the strengthening is mainly by replacing Na with K in the glass, so if it works at all there has to be lots of K in solution to try to do some ion exchange before it cools too much. I think it will cool too fast to do very much, since ion exchange in glass is slow, but maybe it can prevent cracks initiating at the surface.

[@TwinTn]

The process with gorilla glass is done at a lower temperature, about 600 degrees Celsius cooler. Guessing it is molten NaOH and KOH salt, or extremely concentrated, which is very dangerous to splash around, and is prone to explode.

[@albertarason4502]

@@sealpiercing8476 The strength from the drop does not come from chemicals reacting with each other. It's the way the glass cools the drop from the outside to the inside, making pressure while not being able to release it. The more it tries the stronger it gets. Hence the reason for it's super high fracture toughness.

Yep. Same for the medium one if you look carefully. The dent in the steel made the bolr come close, so it touched the tail, close to the drop.

[@Deadpoolbang]

That is exactly what happened.

[@T3ddyRuxp1n]

Makes me wonder if you could form a rupert drop in other shapes? Like if you kept the glass molten held it in a cylindrical shape so that it had perpendicular flat ends. That way the contact area on the press would be larger.

[@gunnison3681]

After watching the 67k drop, it makes me wonder if a very slow, low vibrating weight could be pressed very hard just on the droplet. I think if you reduced the vibrations from the press at least would let one of the drops easily pass 100k
