 Notice real carefully how I put this in the flame although a lot of people will say the hottest part of the flame is the tip That's generally correct We're not looking for the hottest part of the flame here we're looking for the most heat and there's a key difference between heat and temperature and We're looking to heat our tip. We're not looking to get to the hottest temperature in one pinpoint location When I like this, I want to bury the cap in the flame And what we're gonna see is it very little yellow flame And that's really what our objective is here is the less yellow we see the less black and the less soot We're gonna get on our cap when things come up to temperature And now we got our click we're up the temperature used a big lighter gonna give this a few seconds to cool down and I'm gonna show something that's I think real important is that even with a big lighter Give me a click There we go. I can take my cap off and notice I can rub my finger on here and I don't have a bunch of soot on the cap or on my finger. Okay, this is the one. I just heat it with that big lighter Can't say it's perfectly clean, but it's not black if we hold it at the tip of the flame and Since we're all about learning here. I'm going to make this cap black so everyone can see Holding at the tip of the flame You can already see the soot you can see the cap turning black. It hasn't even clicked yet If you just kind of zoom in here, Ben You can see that this cap is really gross Really black if I touch it with my finger. I've got soot on it just from wiping on one spot. Okay, same lighter same cap One's clean one's dirty if you're gonna use a soft flame like a lighter like this Bury it in the flame Make as little yellow flame appear as possible It's actually going to heat your cap significantly faster when you bury it in the flame because we end up with the flame Wrapping around roughly 270 degrees at the cap Uniformly heating the majority of the cap and then conducting that heat in through the cap and heating the tip in the Extraction chamber much more uniformly than if we're just trying to use the very tip of the flame and having the wind blow it all over the place That's no fun.
