Wasn't here for a few days, man has it gone somewhere else! I really don't wanna play this card, but since words don't work, I have to resort to math and physics.
Here I calculated the amount of thrust provided by the water jetpack with Newton's 3rd Law, with the principle like the one I keep telling Papa. It is later confirmed by calculation WITHOUT Newton's 3rd Law. I've also done some calculations regarding thrust a rocket produce with Newton's 3rd Law, with the same principle as what everyone is telling Papa, and again, confirmed with calculation WITHOUT Newton's 3rd Law. I also proved that a rocket indeed works for both atmospheric and vacuum conditions. If you (Papa) think I'm wrong, then show me the math! If you don't, then it's either you think I'm right or you don't understand Newton's 3rd Law.
By the way, if you don't already realize, the link in the image obviously don't work. In there I'm talking about a video which I put in my previous post, go check it out!
