Weak pulsating combustion. An old favorite of mine. I once had a small jar cycle through the night, this process repeating over and over. Also I've a couple of cigarette lighters that work on this principle, just a platinum catalyst and methanol, spontaneous combustion starting from room temperature methanol and room temperature platinum catalyst. You've only to expose the catalyst to methanol vapor, unlike the platinum wire demo where preheating the wire is required.

A big deep-sea fishing saltwater lure maybe.

I always liked this phosphorus painting and the story is interesting too.

What is this???? they call it a jet, but I'm assuming it's a rocket, like a Jetex.

No, El-K, that is a brand new model of the famous MEW 601 air-breathing, gasoline-burning boiled-fuel pressure jet. I once bought two of these brand new for $4.95 each, I think it was.

Of course, in those days, a dollar was something ... I think it was about 1964 or so.

Man, that is cool to see a brand new one of these with bag, instructions and all! But $51.00? The level of performance you get and the low practicality make it a tough sell, to me. Just fueling it up is a fairly intricate business, what with the little fibre wick that has to be threaded down into it and all.

Al Belli should get a kick out of the sophisticated forming technique evident in the manufacture of the fuel pan.

I always thought (even back then) that what would be fun would be to try to re-form the duct so that you would actually take advantage of the expansion of the combusting fuel spray. That would require some really precise design and construction for something so small. It would just be fun to try to carry the design along to some ridiculous extreme to see if a reasonable thrust figure could ever be obtained. If it could be made practical somehow and able to produce meaningful thrust it would be really cool, because it's such an inherently simple idea.

There might be an off chance you could Gluhareff or Loganize that Jet by stationing that apparatus at the side port of a smallish Logan. Side port exhaust might be plenty to sustain the fuel pressurization and you might could transition the "candle flame" heating beneath the cartridge to the side port heat/fire exhaust of a Logan. That would be a neat trick.
