So many stupid comments here. Logical thinking demonstrates that:
A vacuum is space devoid of matter, thus there is no opposite matter to push against the expanding gas of a rocket. The rocket will remain stationary or subject to other forces, like gravity, electromagnetic or atomic. Period.
Thrust for Dummies 101; You don't need a medium (like air or water) to generate thrust. All you need is one thing pushing against another, like two people in a swimming pool pushing the soles of their feet against one another. In the case of a rocket in a vaccuum, all you need is the expansion of fuel in a confined space with something (a nozzle) to release and direct the expanding gas through. And, voila! Thrust.
Remember Archimedes Principle?
"For every action there is an equal and opposite reaction." As for the fuel burn in a vacuum; You're probably not up to the chemistry involved, so you can go back to reciting your A,B,C's and sucking your thumb.
Action- reaction is Newton not Archimedes ....
It seems dummies are doing better than you as you apparently do not know what vacuum means.

My older brother had a term for people like you. You know enough to be dangerous. Not correct, but dangerous.
Rockets do not make their combustion in a vacuum. Liquid fueled rockets for one keep their volitile mixtures separated and by engineering and design will appropriately mix under an ignition source to provide combustion and thus directed out through nozzles to escape their force out as thrust. The vehicle is this pushed through space vacuum or not in the direction opposite to the direction of the expelled thrust.
The fuels are not being mixed in a vacuum, they are by engineered design mixed and ignited in a chamber or chambers and thrust directed out in an opposite direction one wishes to propel the vehicle against.
Why I bothered to explain this though, except to help others begin to understand rocket propulsion and maybe investigate it all more deeply so as to not fall prey to your erroneous words and nonsense experiments here.🤔
That's one of the many reasons why you can not go to the Moon. There's also lethal radiation going on as well as no viruses or virions for life for to sustain itself. No water means disaster within hours.
Oh dear!🙈 You do know that combustion requires oxygen right? And youre awae that 'space' rockets carry their own supply of same? So if you put a real rocket in your vacuum chamber, it would combust the same as if it were in the atmosphere. As for the 'no thrust in a vacuum' idea, where has that been 'proved'. Jet engines do not 'push' against the air, it is the reaction of the mass of the hot gas particles being propelled out of the nozzles. Sit on a wheeled chair and throw a bowling ball. The bowling ball goes one way and you on your chair will go the opposite direction. Basic physics ...
Oh dear! Apparently you are stupid and don't know that thermite and perOXIDE carry their own source of oxygen, Basic chemistry MORON!
What's my name?
Oh for fuck's sake's! Do you know that rockets that are shot into space carry their oxidizers at high pressure and when they light that bitch off they add even more pressure with some massive turbo pumps that create such an extreme amount of thrust that it can shoot a rocket through the fucking vacuum of space. Advanced fucking chemistry that obviously not many people are hip on nowadays! FUCKING GOD DAMN MORON!
NamelessHorse and What's my name ...
Are you calling me a moron or the idiot flerfer?
I agree with both of you as my comment shows .... 😊
I'm pretty sure if you blew up a balloon and dropped it in the huge vacuum chamber that Nassa has that it would simply drop like a stone as it diminished in size . There is a you tube channel that deals with water rockets .you can learn about thrust There.for thrust is thrust is thrust.
