I write books for children aged 8 to 12.
  
  I am currently beginning a book that centers around a 10 or 11 year old 
  boy who finds a submarine kit (it was in a crate that fell off a train).
  
  I need some advice from the experts:
  
  Would it be believable that a young boy could build a small submarine 
  from a kit?
  
  Could the kit be very simple - something like the Silent Runner?
  
  Would he have access to all the tools and parts needed?
  
  Where would he have to build it - a barn? a garage?
  
  Once built, could he maneuver it (on a wagon or cart?) to a nearby pond 
  or lake?
  
  Any ideas or suggestions welcome and appreciated.
