How would one suggest I prepare myself for taking the plunge out of a plane? I was advised to do so.
Sponsored parachute jump.

Read up on military procedures to maximise efficiency and safety.
After saying that and looking the best I came up with was wikipedia:
http://en.wikipedia.org/wiki/Skydiving
I'm sure that you can find information elsewhere if needs by, although nothing seems to be turning up.

Do a firewalk first.
Not as stupid as it sounds - the mental preparation needed to 'take that step' with confidence (having too much fear eating away at you will actually reduce your ability to cope with anything unexpected) is what a well-organised firewalk will do for you. At least, it did for me, though I missed out on the parachute jump a few months later.  |

Fire walk? Did you sunshine?
Wow! Didn't it burn your feet? What was it like??

Very exciting and no, my feet did not burn at all. This was about 10 years ago now, so I'm not sure if I can remember all the details... but the coals were very bright in the late evening that Springtime in Surrey. |

I would love to try that! As well as a parachute jump!
I'm going to do the 'race for life' for cancer research in May at Milton Keynes now i've given up smoking.
Does anyone want to sponsor me?
I've stopped for 13 days now and i feel amazing

I'm Sorry, but NOTHING will prepare you for this experience. Did it before I started PAragliding (less expensive) and I can tell you: WHAT A RIDE!!

That works because of the thin film phenomenon, no? There is a famous experiment where you moisten your arm and then momentarily plunge it into molten lead, all without burning yourself!
I'd also love to do some skydiving

Let's all do it!!??
We could have a mass science forum sky dive worldwide and raise money for an important science research project?
Wouldn't that be awesome!
I'm only doing it though if i can be strapped to an instructor!
I think my legs will become too fluid-like too land properly by the time i hit the ground.
It reminds me of the time i went abseiling and got stuck half way down a cliff face when the spirit of Elvis took over my knee caps.
I was stuck for 30 minutes until i was rescued by a charming mountaineer who then whisked me off for a stiff whiskey.
I didn't do it on purpose, well maybe just a wee bit of damsel in distress acting.

Thats because your feet have a high heat capacity due to the amount of water.  |

I knew that water retention would come in handy sometime.
But seriously, I believe that what you say is the currently favoured explanation - even over the otherwise popular thin film theory that Kalster mentioned. But I have no sources for this opinion.
FWIW, there are a number of other factors involved.
For instance, when the fire is burning, the coals, and the air just above them reach about 750 C. This allows us to claim that the fire was at 1400 F!
But...
The flames actually die down by the time you perform the walk, so there are only 'burning hot' coals to walk on (maybe it should be called marlwalking instead of firewalking?).
Further, though the coals look red hot, this is partly because night has fallen and any lights look brighter in the darkness.
In fact there is already a layer or crust of burnt out ash on the coals, but you don't see it because of the brightness beneath shining through.
So, there are no flames, the temperature of the air above the coals is probably no more than 500 C, there is a nice insulating layer of ash between your feet and the actual burning parts of the coals.
And oh yes, you walk steadily but very positively through it, ensuring minimum time spent in contact whilst preventing any great pressure (which could make your foot sink through the crust!) as might result from running through it.
So no, it isn't miraculous really, but it's still an unbelievable buzz! |
