Hot water

[lepers]

if i plunged my hand in boiling hot water for a second or so, in and straight out, and then straight into ice cold water where i left it, how badly would my hand be burnt?

**NOTE i do not intend to do this**

I scalded myself with running hot water - just under for a split sec, but even though I held it in freezing water for 20 mins afterwards, it still blistered.

I do these things so you don't have to.

I believe this was a technique used by Ghengis Khan on a bent accountant once. He of course dippied the whole person first in boiling then cold water. Nasty.

As above the burn takes effect in real time.

just the thought turns me belly...

OUCH !

I think that once the skin has been boiled, its dead.

the only thing the body can do is shed the dead skin and protect itself with all the goo that fills a blister.

What if you do it the other way round and your skin's freezing and then you dip it into hot water?
I've seen that you can stub out a ciggie with your fingertip if you hold an ice cube for long enough.
