Jason Murphy!
Yes.
You ever get emails forwarded to you with helpful advice?
Not anymore, because I blocked all of them.
Including--that's why you never respond to me now.
Exactly!
[the modulated rogue] The Modern Rogue cuts jars with oil and fire.
So this is one of those that's been circulating.
I saw it online and I thought, "There's no way!"
It was overly-simplistic, and I still question whether or not it works on the timeline that
it shows in the video.
>> Jason: We're going to be cutting glass without actually, cutting the glass?
>> Brian: Well okay, so here's the thing.
I would have called this total BS, except for I got to go work with a glazier.
One of the things they do, is they use heat discrepancy to stress the glass on just the
right part, so when they bang it, it breaks on one clear, thin line.
Theoretically, there's no reason this shouldn't work, which is why as much as it looks like
BS, I think this will actually work.
I saw a bunch of threads on Reddit and so forth, where people tried it and they could
not get it to work.
Oh so it's a challenge now?
I think so!
I've already got my game-face on, bro!
Let's go!
Okay.
So according to the video, our intended outcome is to transform this mason jar into a tumbling
glass, right? >> Jason: Sure.
You can fill the bowl with water up to the line that you want to crack it at, or you
could do it from the inside, right?
Correct.
But, the important ingredient is that you add something that has a much, much higher
boiling point than water.
So in this case, corn oil is going to boil at what, 475 I think?
All oils will boil at different temperatures, but since the water will never get hotter
than 212 Fahrenheit or 100 degrees Celsius, the oil can get very, very hot.
You'll have a very precise band of thermal discrepancy where it stresses the glass, and
hopefully shatters it, right? >> Jason: Exactly!
My suspicion is that less is more.
I assume that we want as thin a band as possible on that corn oil.
>> Jason: You've got to make sure it's touching all of the sides or this will not work.
>> Brian: How do we heat just the oil?
Well, that's why you would have more in there.
Now we want to get the metal red-hot and I hope it doesn't start heating up the tongs.
Melting?
I'm sure you'll be fine, you'll be fine.
>> Brian: All right, boss.
What happens when you dip it down in the water?
Oh yeah, yeah yeah, so the water evaporates keeping itself at 100 degrees centigrade,
and the oil's getting hotter and hotter.
>> Jason: Let's heat it up again.
>> Brian: All right.
>> Jason: Okay, let's try it again.
>> Brian: So you're only dipping it in the oil, you're trying to avoid getting it into the water.
>> Brian: Yeah, you can hear that difference.
>> Brian: All right, give it a try.
Maybe we'll need something with more metal mass so that it can transfer more heat?
These are chunks of iron, and I'm figuring since there's more volume in there it should
retain more heat, right?
>> Jason: Seams reasonable.
>> Brian: It's like we're making a meteorite upon re-entry.
It takes a lot longer for this to heat up!
I think this is a bigger reservoir of heat energy, for sure.
>> Brian: All right, time to call it? >> Jason: Yeah.
>> Brian: All right.
Just keep it gentle, gentle.
You got this.
>> Brian: Whoa!
Now, when I saw glass workers deal with this, they would give it a tap and it would break
along that. I wonder if...
[clanging metal against glass]
>> Jason: Yeah, it's not working.
>> Brian: Ha! Okay, uh...
>> Jason: Uhm.
Yeah, the oil's hot enough now that you are igniting it, which is problematic.
Uhm, okay.
Uhh!
That burned.
Why are you not wearing gloves?
We should both be--go get the big green gloves, that'll be good.
And you could definitely tell the difference between when it's in the oil
and when it's in the water, right? >> Jason: Yeah.
>> Brian: So in the video, do they immerse it down into the water part?
>> Jason: I don't think so.
Okay.
Jeeee-sus!
You all right?
This is a dumb hack.
[laughter]
This is a bad idea.
This is why your bacon screams at you, and throws oil in your face.
So you said there was a bunch of different videos, and some of them had the oil on the
inside and some had the oil on the outside.
You want to try on the outside?
Yeah, we certainly can.
We can just pour that just directly into here and then put the glass in.
All right, I'm going to put the cooled glass in there now.
>> Brian: All right.
>> Jason: There we go.
>> Brian: Oh this is interesting, because we'll have the water on the inside that will be a
kind of leverage against the heat of the oil on the outside.
I'm not debunking this right now, but I'm not thinking this is going to work.
>> Brian: All right, go for that.
>> Jason: You ready?
>> Brian: Yeah, don't get it in the water.
[sizzling]
>> Brian: There you go.
Ooookay.
That's definitely just vegetable oil catching fire.
>> Jason: It's fine!
>> Brian: I'm a little bit not oh-uh.
Little nervous?
Yeah.
>> Brian: Hey, there we go! Now there's no flame.
I'm beginning to doubt your commitment to internet science.
>> Brian: All right.
>> Brian: I mean you can't deny it looks cool, it sounds cool.
You also can't deny that you're playing with a giant grease fire with water, which is pretty
much the worst way to muck around and cut up a glass.
Smells like when I had a deep fryer in college.
I bet those were good days.
They were pretty great.
Okay, maybe maybe maybe that mason jar is just too thick.
So we've got a much, much thinner shot glass here.
This is about the most generous interpretation I think we can give.
Super thin glass, super small amount of oil, so theoretically the oil should get super hot!
I really want this to work.
I do too!
>> Brian: The Space Razor Blade comes rushing to planet Earth, intent on cutting all your cocaine!
>> Jason: [through laughter] What?!
None of your cocaine is safe from Space Razor Blade!
There's no like, magic other step that we were supposed to do?
I don't think so.
>> Brian: I'm like sincerely pissed. >> Jason: I'm a little annoyed.
>> Jason: I feel like the internet tricked me.
>> Jason: It ain't happening.
You can thump it all you want.
You realize, right now in the comments, it's nothing but people explaining to us how we
did this wrong?
You're right, I can see them from here.
It doesn't matter if we did it wrong!
Even if this works, there's no changing the fact that this is a dumb solution, very dangerous,
for a problem that no one has. Fair enough?
Had it been easy, it would have been kind of cool and neat.
Had it worked the first time we tried it, then it would be something we could show off
at... you know, glass parties, or whatever.
When we go to glass parties.
When we're hanging out, we're like, "Okay, all I need is some cooking oil and thirty-five
razor blades and also do you happen to have a benzine torch?
That would be really great."
This is a dumb trick, nobody cares!
I know, you're taking it personally.
It's okay, I'm mad too.
I am taking it bad--I'm taking you personally!
I'm out!
Don't take it out on me.
It was your idea.
