Welcome to hydraulic press channel.
Today we are going to finally crush the Prince Rupert's drop,
and if you're not familiar about this, it's harder than glass drop.
This big head over here is very hard, and you make this by dropping molten glass into water
and when you are doing that the glass is hardened and also because the surface of the
glass cools down faster and the inside of it is still like molten and very hot. When it cools down
there is really high tension built inside of the glass so the head is very hard but the tail of the thing is very
not hard. And if you break the tail the whole thing explodes
and here you can see how that goes. So, yeah it’s really interesting piece because, it’s same time really hard and really weak.
And thanks for Suomen Lasinjalostus for making these and I think these are really big ones
I didn't know you can make this big ones, but now we have them and yeah, let’s crush them.
And here we go!
Holy shit!
Glass smoke, don't breath that. I'm looking and I'm not sure if you will see that but there was like glass smoke in the air,
because the thing exploded so hard.
So the thing was very hard.
I was really surprised how
big the explosion was and, here you can see there is small dent here and here that the thing left
and, I think we are going to explode another one and this time film the pressure meter so we can see
how strong the thing really is.
So here is the second drop that we crushed the pressure impacted crushing the drop causes
to press it so fast that the pressure meter couldn't measure it. But I think it was above
10 tons according to the dents that the drops made. But I also added more speed to our
chronos high speed camera and I think this is actually first time on video when you
can see the drop end of this exploding and the shock wave goes to the direction of the tail and not the other way around how it’s usually done.
Yeah there was our Prince Rupert's drops,
but because the guys at the glass company were so excited they gave us this glass kettle bell
to be crushed.
And then we have this outdoor light which just made out of
recycled glass and plastic and this should be really tough so let’s see.
And here we go!
That wasn't that tough than I was thinking because usually if some thing is made
out of plastic and so big its going to be bad day, but I think glass inside of the plastic
quite, like, saved us.
But I think it doesn't matter what lamp you throw there,
it’s going to be crushed up there our press. Yeah but let’s try the kettle bell next.
Yeah, I think this is quite good lesson about what's difference between hardened glass and
just regular glass the kettle bell went out quite peacefully when you compare it to the Rupert's drop
Yeah but I think that was all for today, thank you for watching, and have a nice day!
And for today's extra content we have this komodo dragon
which is like really big ass lizard.
And I think it’s somehow poisonous or something like that, and it’s also very big so it’s extremely dangerous,
and we must deal with it.
