I see what you mean by the boat, I guess I should have caught that. As for the other two, well, if the law wasn't true the ground would fall away from under us, or something of that nature, but it doesn't really have anything to do with propulsion and direction, does it?

This is a ..."thats true... nasa knows everything, and i just wanted to say that if y'all have come to an agreement about this topic, then you know, i havn't read all the commens yet so... just let my before you get irritated or something about this comment:
Space us litterally "space" its practically nothing,thats why you have to where a space suit, so the pressure wont kill you. there may be something, there may not be something that can ppush on the foam coming out of a fire extinguisher, and propell you foward. so... im going to argue both sides...
there is oubviously matter in space, there may not be much, but there is some. so... according to Newton, and you may use or combine any laws you wish, if you push on that little matter with a fire extinguisher, then you must go foward. even if it wasnt the foam against the space, perhaps it was the foam against the fire extinguisher, or the fire extinguisher againsat you. in any case, your going to move, how else do astronauts move in space?
due to the fact that space is near nothingness, there isnt enough of anything for you to move when your only using a fire extiguisher. first of all, the foam would probably go everywhere the second it entered the nothingness, maybe even before, so that would cause problems if your trying to use it as a transportation method. newton's 1st law says that an object in motion will remain in motion at a constant speed in a constant direction, and an object at rest will remain at rest, unless acted on by an unbalanced force. so, if you are at rest in space, a fire extinguisher is hardly an unbalanced force...
cant we agree that WALL-E is a cartoon and the people who made it wwere animators, script writers, and actors, not scientists

im not gunna say anything cause i dont exactly know

Actually, I just figured out that they do turn, using thrusters.Problem solved on that point.

That second point actually proved the third law in the last two sentences. The second sentence stated that the water pushes on the oars, not the boat, but you are holding the oars, the boat is holding you, and so if you stay firm, the boat moves.
Jumping. Your action force is pushing against the ground, the reaction force is the ground itself, being there to provide something for you to push off of, pushing you up. Action, reaction. Then, of course, gravity pushes you down. And gravity also always acts on you. Always. It just isn't a very strong force, and so the action/reaction force that you apply is just stronger.
Jumping is actually explains by both laws. They both apply.
But the laws have everything to do with it, you just don't quite understand what they are explaining.
