Propelled by Liquid Oxygen & Methane, Nasa test fires it's small scale prototype  XR-5M15 Rocket

See it HERE

NOTE the tear shapd white clouds within the blue flame ?...they are called Mach Discs....shock waves created as the vaporising fuel meets atmopspheric pressure outside the nozzle !!


cool eh ?

Yes I agree this is very interesting.Also just a slight correction on your post, its not actually vaporizing fuel that is creating those sonic discs but rather the exhaust of the burning fuel coming from the combustion chamber that is exiting the nozzle at supersonic speeds.

Well a rocket motor is not as economic on fuel as your lighter might be if I understand you post correctly.But your lighter can not beat this the raw power of a rocket motor running at full power. [;)]
