Jam Jar Jet by Night

My best jam jar pulse jet engine so far, running at night so you can see the flame, with the added bonus of a spectacular finale.

what the hell i did that and nearly had a heart attack!!! why did you put instructions on how to make one

[TheLangfords]

@wertacus Exactly so you could make one yourself. Have a browse around Instructables, there are nearly fifty thousand projects there now - at least a few of them won't scare you (although The World's Largest Party Popper [you'll have to search for it] might make you wet your pants...)

Can U Use Petrol?

[TheLangfords]

@jadejordan1 I have never tried it, and I recommend you do not, either, as petrol vapours are highly explosive at a wide range of air/vapour mixtures.

It's too likely to go dangerously bang.

Nice to hear bells, where is this? 

[TheLangfords]

@pal05pmajor3 Suffolk, vaguely near Lowestoft.
