1:36:41Exactly. um the >> striking band >> striking band that striking surface, you actually want a a more granular structure in that granite because as it hits one another, if it's a really nice crystal, there's going to be cracks. >> Mhm. >> Right. So, what you want is the two different things, the two different parts of the stone to have different sort of chemistry. >> Yes. because they they have two different functional areas where they're relevant. Yeah. Uh one for making sure it gets down the ice quickly and sufficiently and the other to make sure when it contacts other stones, >> it does so in the most

1:37:22>> and and like it's like a really nice elastic collision that we read about in physics textbooks. Momentum is conserved. There's no like nothing lost to heat and things like that, right? >> Okay. So, >> somehow there's only two places where there's these good stones. I am convinced this is um a racket. >> It's a racket. >> Like >> racket. >> There's no way, [laughter] dude. But look, okay, so people tried to make an effort in Canada in the 1950s. They tried to use the very black ignous rock called an orthosite, >> okay, >> to make these. And then those things just started chipping way too quickly. Like the the stones would get damaged. And speaking of the Canadians, they are

1:38:02now cheating in the Winter Olympics. I don't know if you guys saw this, >> but dude, this guy So, so you know, you're only allowed to um >> you're only allowed to grab the handle and then let it go before that line. This guy was grabbing the handle, letting it go, and then pushing it with his finger. And then when the Swedes called him out, he like literally started yelling at them and told them to f off. And then the Swedish NBC, these guys are these guys are the OGs. They placed their own camera because the the the Olympic cameras are placed like here and and behind. So the guys could have gotten away with that. >> So what you're saying the initial comment of the initial complaint was prior to the video evidence.

1:38:43>> Yeah. Because this is a known thing that this Canadian dude does. Okay. And so the Swedish guys for the CA Canada versus Sweden match, the Swedish NBC, their television put a specific camera at that spot and caught this guy redhanded. He did it again against the Swiss and I think now he's facing penalties. The judges were just like not doing anything. >> Yeah. Yeah. Yeah. Yeah. >> Because they were like, "Well, I don't know if he did it or not." Well, now it's like we got a specific camera that's showing that he did it. I guess it must be the case that no one was dumb enough to do it, which is why there's no like goal line technology for this currently curling. But it seems obviously true to me that like if that's the rule and there's an advantage you

1:39:24can get from breaking that rule >> because you you you give an initial momentum and then a tiny a tiny nudge will like because the the you know the the the target is meters away. So even a tiny bit of nudge in that angle is going to cause a huge deflection later on, right? It's not nothing. very very very sad. Look, we're trying to continue to establish and repair our North American relationships with the Canadians. >> There's several things to be upset at us about, but we are now upset at you guys about this cheating. >> That's that's BS. >> Let's not just remember it's the As Bad Bunny said, it's America and then listed everybody. And so we got to be on the same page here. No cheating in the

1:40:04Olympics. >> Yeah. Yeah. Yeah. I want to beat Sweden as much as anyone. Okay. [laughter] But like >> we're on the same team on this one. Okay. >> Okay. And um the next thing about
