NG Power test
Charge: 
 
The charge was a straw with 0.5 gr AP to initiate the 1 gr NG, that was soaked in the string, wrapped around the straw.
Check the String Dynamite page for a pic of such a typical charge ...
 
This was then placed in the iron testing tube (with a wall thickness of about 3 mm), and the 
whole thing was buried in moist ground at a dept of about 30 cm ...
 
  
As you can see, testing tube is totally deformed, and I even lost a piece of it !! 
I did searched a bit for it, but who knows how far such a thing can be propelled in the sand ...
 
  
This was another cool test, I really had fun and it showed me the 
potential of that vial of NG !! (Fun times are ahead of me :-D )
Addendum: some more power testing (god I love this stuff)
Check out this   vid !!
It's the result of no more then 2 ml of NG !!! 
(same type of charge)
