How to make a Jam Jar Pulse Jet

The jar is a 250ml pasta sauce jar with a 3/8″ hole drilled into the centre of the screw lid. Pour a approx. 1 tablespoon of Nitro modellers fuel into the jar. (I used 19% but if you have hotter stuff, then please let me know the results!) Shake well, to mix the fuel vapour with the air inside the jar, stand back and light! The jar is placed in water, in an attempt to keep cool but as you can see, it doesn’t work! I have had up-to 1mins burns before now! The shape of the jar is important, it needs the narrowing neck to act as a venturi, to help speed the flow.
