I put myself on the line to see who wins in the Battle of flame thrower versus era Joe.

Adverbs of degree

So if you really want to see the insulating properties of aerogel, you gotta put it to the test.

And this material here is like the most insulating right.

It doesn't look like the blue stuff because it's actually a fiberglass blanket that's infused with aero gel by the blue stuff.

Oh, it's made of the same material as sand or glass.

But if you zoom into the nano scale, you'd see it has a sponge like structure with tiny pores just tens of nana meters across.

Now Air Joe could be up to 99.8% air, but it's a better thermal insulator than air because those pores are so tiny that hot air struggles to diffuse through them.

Plus, the nano scale structure itself is a poor conductor of heat.

But marriage oh is pretty fragile in this form, and so it's not really practical for most uses.

Instead, what you can do is actually take tiny particles of marriage.

Oh, and embed them in a composite material like blankets.

But it has an additional component iron oxide, just basically rust that makes it opaque to infrared radiation.

So it's good stifling conduction conviction and radiation.

And on the other side of this insulating air gel blanket we have bent.

He's from Cape Cod and responded to a tweet of mine when I asked if anyone in this area has a flame thrower or a not a flamethrower, in this case from the boring company.

Okay, So what we're gonna do is try to test what the temperature is on the far side of that blanket when we put the flame thrower at full bore onto this side.

This is the T 10 20 which can record up to 2000 degrees Celsius.

Let's see what this flamethrower it can do to something that's not marriage.

Oh, let's put it to the test on this supersized Hershey's kiss.

Within seconds, the temperature of the chocolate is up to hundreds of degrees Celsius around 30 seconds.

The whole thing starts to collapse even after the flamethrower is removed, parts of the chocolate are still well over 600 degrees Celsius.

I think this is what the Internet likes, like, really hot things applied to, you know, novelty objects.

OK, now is the time to really put Ara gelato test.

He's about to put the flame for our full board on this side of the blanket.

Just one centimeter away will be my hand on the back side of the blanket.

That is three propane burns at about 2000 Celsius.

So this flame door was producing over 660 degrees Celsius on this side.

Meanwhile, on the other side, we're just measuring about 50 degrees Celsius.

We're going up to the highest range that this camera can do up to 2000 degrees Celsius.

Okay, We're not gonna be able to see much except for the really hot stuff.

Yeah, it's actually still it's over 200 degrees Celsius right now.

Can you see my hand prints after I touched it?

Now you might be wondering how it's possible to touch something hotter than 100 degrees Celsius without getting burned.

Well, for that, we need to go to another demonstration.

This is a hot plate set to around 150 degrees Celsius.

And on top of it is a metal plate that is mostly covered in about a millimeter oven hair gel coating called airline.

But a small square in the corner is left uncovered.

So would you put your hand in boiling water?

But what about putting it on this coding?

It feels hot, but yeah, but it doesn't feel like 100 30 degrees.

There's some water in a little beaker when I move that figure.

So I was cooling down the surface over here.

It's about it's well 180 degrees Celsius.

So that is the part I don't want to touch.

Yeah, definitely want touch because it doesn't have a radio.
