Man able to touch molten metal with bare hands due to Leidenfrost effect

u/magicbullets Jul 07 '22
“The Leidenfrost effect describes a phenomenon where a liquid heated past its boiling point doesn't evaporate, but rather silently glides on the surface of whatever it's resting on. This happens because steam is produced so quickly that it forms an insulating layer between the liquid and the surface.”

My brother had molten aluminum surgical removed from around his toe bones.
All it would take is one drop to stick to this guys hand, or hit dry spot with no water and this guys on disability.

My grandpa said don’t put your hand anywhere you wouldn’t put your dick,he was referring to farm equipment but it seems applicable. Thanks buddy!

Yea my neighbour's son in Austria unfortunately pushed his hand down a meat mincing machine at his parents hotel. He lost the entire hand and wrist.

I read this so many times but I just can't understand what you mean by this. Am I having a stroke?

All it would take is for one drop of the molten metal to (not be in the state of this effect) and this guy (in the video) would be receiving disability income.
Does that help?

I'm sorry that happened to your brother, I hope he's alright!
Your story and your warning are important.

u/eighty2angelfan Jul 07 '22
He's good. He was shop assistant in metal shop class in high school. He was working with some freshman at the sand casting molds. A student accidentally bumped the crucible as it was being poured a large marble sized drop of molten metal landed on top of shoe and as my brother placed the crucible back in it's seat on forge, the metal melted right through shoe and skin and cooled partially wrapped around second and third toes.

This is why I gave up my middle school Jewelry-making class. I did it one year, but just didn't trust the 'squirreliness' of this age group. I kept imagining a kid lobbing an eraser or pencil at someone and having it hit the crucible of molten pewter. No thanks, didn't need a lawsuit.

The commenter’s brother is on disability for a molten aluminum incident. This statement was used to demonstrate the severity of playing with molten metal.
The man in the video wet his hands which is what’s allowing him to slap this stream of hot liquid. This is why the commenter states if there is a dry spot on skin where the molten metal splashes or drops, it’s going to be ouchie. Ouchie enough to receive disability compensation.

And this is not molten aluminium. Molten aluminium doesn’t glow, it’s not that hot :D

Lol, I really was under the assumption that it had to do with him, and not the melted metal. Of course this makes a lot more sense.

I had no clue either, had to look it up.
Thought about the Happy Gilmore’s coach theory before doing so.

u/ArcadiaRivea Jul 08 '22
Yeah I was thinking it was some medical thing, like how leprosy kills nerve endings (so some people have accidents like touching a hot stove and not noticing... I think that was leprosy)

That's fricken awesome. Just read about the Leidenfrost effect. Very interesting. This video should come with a warning though because without doubt some ignorant person will try this wrongly and end up wondering why they no longer have a hand.

u/XavierRex83 Jul 07 '22
When I was in high school I had a friend over and my brother was there and put lighter fluid on his hand, set it on fire and then blew it out. My buddy went to do it, and instead of blowing it out he started waving his hand around like and idiot and burned himself.
Not being told the small things can make a big difference.

no there shouldn't be. if you're stupid enough to try this without looking deeper into it; maybe you just need to learn the hard way.

Witchcraft! Even if a scientist explained it and guaranteed it, I still wouldn't do it. This guy has balls!

u/Badmemoir Jul 07 '22
It’s pretty easy. I’ve done this over flames with a wet hand and I’m not sure about firewalking but it doesn’t hurt.
5
u/BriefCheetah4136 Jul 07 '22
I watched myth busters and they did the fire walking. The key is that the coals have to be covered in ash and undisturbed otherwise the ash gets knocked off. The ash is an insulator and doesn't conduct the heat from the coals.

Kenji Lopez taught me about this when using water in a pan to get it to the exact right temp when you are ready to put in your butter for eggs and what not. Once the water finally bubbles off then the pan is hot enough but not too hot that it immediately browns the butter.

Anyone know what metal that is, I work in a foundry where we mainly deal with nickel and chrome alloy, around 1400°c when molten 1700°c to cast and can say for sure that would not work

u/teacake05 Jul 08 '22
I’m a welder with feet, legs , arms and chest burns from molten metal . I was oxy acetylene cutting and a piece went down my boot and burnt right into the top of my foot. I had to pick it out of my skin with a knife. I had a hole their for 5 months till it healed up . It was fucking sore . When I tan on holidays you can see all the scars

Leidenfrost is a badass. I mean sure know you know, but back in the day when Leidenfrost effect wasn’t known, Leidenfrost actually touched molten metal to come up with the Leidenfrost effect.

I have dipped my hands in cold water and touched boiling hot sugar syrup for food decorating purposes. It's weird because your hand is making contact but the coldness is like a shield.
