Molten lead vs. Hand, the Leidenfrost effect

showing the leidenfrost effect with my hand and molten lead!
wiki: ''The Leidenfrost effect is a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer which keeps that liquid from boiling rapidly. This is most commonly seen when cooking; one sprinkles drops of water in a skillet to gauge its temperature—if the skillet's temperature is at or above the Leidenfrost point, the water skitters across the metal and takes longer to evaporate than it would in a skillet that is above boiling ''

@bidoa I think you need glasses

Why doesn't this work with hot oil?

[JoaumlEphgb]

@AaronX85 Did you tried? Well, there may be many reasons about why it doesn't work with hot oil, but I'd say that it's because it wasn't hot enought for the leidenfrost effect.

what is the song???

[JoaumlEphgb]

@fmeriqui Angra - carry on

[snufleufugus]

I can't think of a more mismatched combination of music and video

awwww its a baby T-1000

[jeffddow]

hey i got a serious question if i work with molten lead are there any precautions i need to take to prevent lead poisoning?

[kaas94]

@JoaumlEphgb because oil floats on water because its lighter??? I am not sure tough.

[kyunghi]

the song is really gay

@AaronX85 Oil isn't typically hot enough. Basically you need sufficient heat to instantaneously vaporize the water into a protective layer of steam. Melted lead heated to an excess of 800 F would be hot enough.

@JoaumlEphgb No I haven't tried, but I get the feeling it won't work. Maybe I should try (with something other than my hand).
