   Very cool!  Is that one of those so-called "Stomp Rockets"?  What is the 
max pressure to which your stainless tank is tested?  I wonder if too much 
pressure would blow the nose off the rocket instead of launching it?  2 bar 
is just about two atmospheres, isn't it?  Never mind, I have a calculator 
here ... yes, 1.97 atm, or 29 psi.
   Gee, I wish my kid was purple, too.  (Just kidding! :)  Anyone else have 
problems with the colors?
   That is a VERY cool jeep (DAK?) on the home page.
