@tripolarbear Let's have a look

with nothing to push off, rocket doesn't move

A feather and a rocket are different in their composition and structure.

if you want evidence on why rockets work just fire a gun you live in the us right?

they both use air to move

and just change the density of the projectile

A feather is made up of a bunch of loose parts while a rocket is one solid object.

eg a heavyier bullet

running fan is using air to push a feather, move it

@tripolarbear So why isn't it moving?

rocket uses air to push itself, to move it

because its anchored

in a vacuum neither moves

you cant have your rocket flying around your vacuum chamber can you?

that image I ~~showed~~ mentioned above is inconcslusive because of the parameters of it

@^Kevin^ use a bullet with a weight then compare the recoil to a bullet that weighs more but has the same velocity

different recoil

Could you people listen? I've tried saying that when the gases in a rocket evacuate the chamber that they are in, the leave out through a cup shaped nozzle. The gas accelerates because the diameter of the nozzle changes, resulting in a force. Newton's Third Law, the opposite force is being applied to the cup of the nozzle

they dont believe in newtons third law

lets not overcomplicate something already complicated by bringing guns into it

rockets "push" off air apparently

@tripolarbear Only when it suits them it seems

guns wouldn't work in a vacuum because the gunpowder wouldn't ignite without oxygen in the air

The gas is pushing on the rocket, the gas isn't pushing off of the air

you'd need a gun that would work underwater for it to work

but in nz we dont worry about people carrying around hand guns and suicides are less?

like a spear gun

its smokeless powder

that has no relevance to vacuums and rockets/fans/feathers

gun ownership is directly related to suicide succesfulness

@^Kevin^ Alright, what about what I said then

gun usage*

you cannot throw yourself forward with your own hand

you have to push off something

or walk

or swim

@tripolarbear Care to explain please why the rocket does not move but mister flappy however does and moves in the WRONG DIRECTION ?

Yes, and the gas is pushing on the rocket as it is leaving the fuel chamber.
