Photoshop. I can tell by some of the pixels.

well I know there's a Mythbusters episode where they make their hands wet and then put it in molten (300°C) lead. In that case, the vapor over your hand surface protects you from burning as long as it's there. Might be something similar. If the hot stuff doesn't stick, you're good.

It's called Leidenfrost-Effekt.

The thin barrier of water and oils on his hand are sufficient to protect his hand. Heat transfer takes time.

either photoshop or the hand oils protecting against the molten lava

This doesn't make sense to me, the oils on my hand dont prevent me feeling pain from hot surfaces almost instantaneously.

>>9640016
Try again

>>9640021
But be careful.
The standard demonstration is to flick a hotdog in and out of molten lead.
If the lead isn't hot enough it freezes and prevents you from withdrawing the hot dog.
This does the hotdog no good and would do your hand even less.

The temperature gradient needs to be steeper. The moisture on the hand needs to nearly instantly vaporize, this will form a vapor barrier around the skin that will insulate the skin for a very short period of time. If you touched someone for a fraction of a second and it burned you, it wasn't hot enough for the effect to occur. This is dangerous and do not try this with your body parts at home. Put water in a hot pan or something instead

Slavs have higher pain thresholds /thread

You can slap your hand against super hot things and not get burned as long as the duration of contact is super short. Heat takes time to transfer.

You get burned from grabbing a pot because youre grabbing it.

i can too move my fingers in flame, but gotta do it quickly

He didn't wet his hand and the liquid metal has temperature of like 1500 degrees science or more

>>9639792
Hes been working with liquid metal for so long his hands turned into steel.

>>9639792
His hands were sweaty from working in those thick ass gloves and the layer of sweat protected his hands from being burned.

>>9639792

He's obviously some kind of superhero

>>9640419
>molten lava=fire
Seriously hope this is bait

>>9640440
Sweat

>>9639792
1) That is pretty badass.

2) I like his hat.

>>9639956

Do you guys think he works in some sort of Russian lava factory?

>>9640440
>He didn't wet his hand
how do you know? there's clearly a cut right before he actually starts the trick

>degrees science

>>9639792
The flow of molten metal isn't sticking to his hand, so I guess the liquid metal is flowing too fast and doesn't stay in contact with his skin long enough to transfer enough heat to burn his hand. Also, by slapping it, the amount of metal that effectively is capable of transferring heat must be minimal.

The powers of chad are ubhear off

Same thing that happens with dry ice submerged in room temp water

Rite?

Same effect as wetting your fingers to extinguish a candle.

What kind of post-Soviet shithole is this where the guy's respirator is just a tube he holds in his mouth?

ornn was busted a few patches ago im glad he isn't anymore

>>9640264
Weeeew.

>>9641143
What kind of retard at you to think metal workers use respirators?

>>9641143
Its obviously just so he breathes cooler air outside of the convection column

>>9641644
It's not even a respirator. That anon is just dumb.

>>9641506
It's still the same effect.

>>9640016

Lick your finger and tap a hot clothes iron.

>>9641629

That was beautiful.

>>9641630
Metal fumes can be highly toxic

>>9641630
What kind of retard are you to think that breathing the gas coming of molten metal is generally safe?

>>9640755
well how else would they make all their secret lairs?

>>9639843
This + low viscosity.

>>9641629
What is happening here?

why are you posting pictures of one of my sons?

Yes that's really spicy water.
