False. And very silly: How can the gas suddenly push the gun after having bounced off a bullet, if you claim that it can't push if from "bouncing out" from the gun in the first place?
The gas pressure in the barrel pushes both ways; against the gun and against the bullet. However, the bullet is not important for the rocket effect. The gas itself is accelerated, instead. Hans |

Proven right here that there is no equal and opposite force from gas movement due to pressure gradient force |

Gingervytes, when you can take a break from pretending that Newton’s Third Law only applies when you find it convenient, would you be so kind as to answer the questions and refutations I’ve already put to you, but you have ignored so far? Here, I’ll repeat them for you:

No you haven't, as evidenced by your continuing to make the same mistakes the video does. You don't understand what momentum is, where it comes from, and what its effects are. This is why you keep posing what you wrongly think are analogies to rockets, but conflate elementary concepts like gravity.
You were shown how the video conflates other physical effects such as gravity and buoyancy. You have not rehabilitated your argument in the face of that demonstration. Simply repeating a debunked claim does not overcome its refutation. |

Remember when self-styled super-engineer Anders was over on apollohoax, blithely not understanding conservation of energy? This reminds me of that, in particular the counterexample I gave him of a non-propulsive mass jettison. Dunning-Krueger in action.

“Conservation of momentum is a fundamental law of physics which states that the momentum of a system is constant if there are no external forces acting on the system. It is embodied in Newton's first law (the law of inertia).” the external force is pressure gradient force, not from the rocket

No, that's not an external force. Gravity, for example, would be an external force for a rocket. The propellant contained in the rocket, and sharing its velocity state and mechanically coupled to it, is part of the rocket system. Since you were asked twice to address the refutation of your video, and you have declined both times to do so, can we agree that you have no rejoinder for the refutation and cannot rehabilitate the claims your video makes?

I can barely believe that a person can so willfully ignorant about basic concepts and the results of well established facts.
After all, rockets have been successfully operating in the vacuum of space for well over 60 years now. In fact, if rockets could not operate in the vacuum of space, then it would not have been possible for the Apollo astronauts to go to the Moon and back in 1969 (plus a few more times after that). |

There's a two-player Cheese Shop game in The Brand New Monty Python Bok, in which one player - the customer - asks for various different types of cheese, and the other - the shopkeeper - has to think up a new excuse as to why he hasn't got it. I think it's important, for those who are trying to persuade Gingervytes of his/her error, to realise that he/she is not seeking information or correction here, but playing a variant of the Cheese Shop game, in the role of shopkeeper.

To posters familiar with this kind of argument: I run on the assumption that woo believers were never properly educated on the fundemental physics, then they run across a woo peddler who slides in absurdities under the guise of critical analysis. It would by necessity have to be dumbed down and missing critical components to be plausible, but seem to the new woo recipient to be scientifically sound, hence the resistance to correction. Is this the typical M.O.? I confess the psychology is a little fascinating
