Looked liked CA, not hot glue?
Despite all the impressive engineering, I also wondered if it was actually a functional jet engine at the end. In all the wide shots the starter motor is clearly being used, and at the end where the caption says "Self sustaining mode" the framing carefully hides the intake end of the can, so you can't see if it is actually running without the starter, or is just a motorised flamethrower.
