The noise is something else - I think it's a Pulse Jet (whatever that is). I can handle top fuellers and the jet cars, but the noise of these (there are two) made me feel sick!

The V2, developed a bit, (well, a lot) by Dr Wernher von Braun was at the heart of the Saturn 5B....The V2 used liquid oxygen and 75% methanol, 25% water, the Saturn 5B used Kerosine and Liquid Oxygen. I've often wondered why the V2 didn't use kerosine, one explanation was that the Germans, at that stage, simply couldn't make enough for their ME 262 jet engines, otherwise they would have done so.

Pulse jets are (to me at least) really interesting. They are very simple constructions, a long tube, and the valve (which "pulses", hence the name) is typically only a couple of inches in diameter. Lots of info at https://aardvark.co.nz/pjet/valvelife.shtml I recall seeing/hearing them in use in control-line ("U-control" in the U.S.) model aircraft in the 1950's, as demonstrated at https://youtu.be/Q9-weExLUA8 and https://youtu.be/OL7VgWe_zmk Unsurprisingly, the H&S aspects mean they are a rare sight and sound nowadays.
