[GreenKeys] Tubes

[Jon Schlegel]

Larry,

Excellent post and outstanding link!  Without subtracting from the 
subject matter, the "John Dillinger" scene with the G-man and Tommy 
gun were classic.

Have fun with the family's curiosity.  My trigger point was in 2nd 
grade when the teacher sent me home with a book on electricity.  My 
father built up the experiment with the coil of bell wire, compass 
and D cell.  Seems I just didn't get bored watching that compass spin around...
