in high tech warfare, this propane powered gun can propell a 1000 degree fireball
about 10 feet. I have not pictures of it at this time, but it consists of a
copper pipe, leading to a piece of 2" ABS. This then is reduced in size
in a series of reductions, eventually being about 1/2". This then leads
to another piece of 2" ABS put over the entire reduction series. After
about 7" of ABS, an air intake was added, this is a gap of around 1/4"
in the ABS. This process allows the pressure of the propane to build, eventually
re-expanding in the ABS, and mixing with air for added burn.
