Jam jar pulse jet with HIPP jar and watercooling LONG RUN

I think this is how it works...

1) A fraction of the combustible ignites consuming all the oxygen inside the jar and hot gases (CO2 + H2O) come out of the jar

2) The low pressure generated inside the jar sucks in more air through the small hole on the jar lid and the the ignition of another fraction of combustible happens again

The repetition of these cycles is what generates that pulsating farty noise....this technique can be even used to generate thrust in aircraft engines
