LOL! Too funny Brian!
Since when would Voldemort know anything about that nuclear stuff that 
Muggles use? I suppose he could try and sneak the information out of 
Arthur Weasley!



He got Arthur under the Imperious to find a super-weapon and Arthur 
tried to take it apart as he couldn't see what was clear about it, even 
if it did look new.
That's why he ACCIDENTALLY blows up London and Harry and himself

Although I didn't think much of the sixth film (but then the book wasn't 
my favourite either), like you, I'm really looking forward to the 
Deathly Hallows films.
There's  lot of real emotional stuff in there.  I hope they don't strip 
it out like they did that wonderful scene in Half Blood Prince where 
Fleur declared her love for Bill after he was attacked.
