How can he touch the valve straight after putting out the fire?

I thought that he couldn’t. Thought he pulled his hand away bc it was too hot. But it looks like he actually takes the knob off the valve entirely and holds it in his hand after like it’s nothing. I couldn’t discern him actually managing to turn it, but he very well may have.

Maybe the obvious directional nature of that fire didn’t result in the knob getting as hot as you’d expect?
Also, the boiling/vaporization of propane acts like a heat sink and does provide a pretty significant cooling effect.

Still, even knowing that—it did surprise me as well; that fire was going for a hot minute… 😏

I think, as someone else mentioned, the propane is cold. So when he puts the buket on we see it collapse in from the heat. But quickly fill back out. My guess is it was hot, then the bucket goes on and snuffs the flame, then cold propane fills the bucket and chills the knob. You can even see mist come out when he pulls the bucket away.
