The rule of s– radio engineers is always have the one hand in one pocket … and just use one hand.

KATE HUMBLE
undefined
Really?
undefined
JH
undefined
Really yeah ‘cos if you’re holding the chassis of things and you get electrocuted, it’d be bad.
undefined
KATHY SYKES

Okay and the thing is, this huge voltage right … we’re expecting a little spark to happen inside there.
undefined
JH
undefined
Yeah basically when the current goes through, it produces a magnet … which attracts this … and then turns it off … and so initially all that energy that’s stored in there then produces the spark, it breaks down the air.
undefined
KH
undefined
Because … electricity can’t usually go through air, can it?
undefined
KS
undefined
No it’s just like a little tiny lightning bolt, okay?
undefined
JH
undefined
Breaks down the air …
undefined
KS
undefined
So it’s a little baby lightning strike.
undefined
JH
undefined
Yeah, not a big one …
undefined
JH
undefined
Yeah, not a big one …
undefined
KH
undefined
That’s incredible.
undefined
JH
undefined
It’s only going to be a little bit, but it shows you how much voltage there is.
undefined
KH
undefined
Okay, am I allowed to swap between you so I can see it?
undefined
KS
undefined
Sure.
undefined
KH
undefined
Okay well let’s hope it …
undefined
KS
undefined
All right, are you ready to go? Hand in pocket like Jonathan says, here we go … Oh wow!
undefined
JH
undefined
You can see the sparks.
undefined
KH
undefined
Bright blue!
undefined
JH
undefined
Yeah it’s lovely.
undefined
KS
undefined
Hey … hey hey hey I want to see now.
undefined
KH
undefined
So is it almost like when there is a storm going on, and you’re watching TV or you have a radio on, and you get … it’s like an interference or something, is that basically how this is working?
undefined
JH
undefined
Yeah, I mean this is actually producing radio waves but we don’t call it interference this time, because it’s actually a noise we want, but it’s radio waves, that interference is actually radio waves that you don’t want, so you call it interference.
undefined
KS
undefined
And you’re absolutely right, that’s what happens when lightning strikes.
above is the spoken text i need analysis of the main function of each turn in the conversation in terms of command, offer, question and statement, discuss how this conversation analyzes and explains the relationships between the interactants. Think about the distribution of turns, the function of turns, and the lexicogrammatical realizations.
