//Every action has an equal and opposite reaction.//

The Rocket is a relatively simple and common example, but it is a good one. As displayed in my diagram, the a ction is the engine starting and the reaction is the rocket shooting upwards. The rocket actualy is a good example for all three Laws Of Motion, but I'll explain that in their respective pages.

Balloon
Balloons are quite similar to space rockets. You think I'm insane??? It's true. The diagram for the rocket works well for the ballons as well. When you let go of a filled ballon the air inside turns into the force propelling the balloon into spinning around the room. The actual spinning is caused by the end of the balloon (where the air comes out if) flapping around behind the balloon, redirecting the flow of the action (air) and in doing so changes the reaction (direction the ballon travels) to opposite the flow of the action (air). That was probably way more confusing than it had to be, but you get the point. If not, I did an experient on this example. Find it on the "Experiments" page.

Airplanes - Elevators
A awesome example of the third law of motion is the airplaines. If you've ever seen an air show, you might have thought that the tail wings of the aircraft were moving, but threw away the idea because it sounded silly. Actualy, they realy are. airplaines go up and down using two flaps called elevators, which on a large, Bowing 747 would be flaps on the wings, but on smaller aircrafts like fighther jets or Nighthawks are the whole tailwing. Basicly, when the elevators go up, the airplane goes down and vice versa. But how and why does it work? well, in the ilustration on the left you see how. The orange and yellow are paths for the air molecules, one above the other below the tailwing. The Elevators work in a sort of vacuum efect. When The yellow molecules ramp up it creates high preasure above the tail; and when the other path is completely uneffected there is no change (but it is still low preasure- as labeled). When you suck a straw the low preasure un your mouth and the high preasure in your Pepsi sucks the soda into your mouth, and that is what is happening here, but in reverse... and I'm rambling on, ar'nt I? You get it though, dont you? Elevators going down (or up) is the action, plane going up (or down) is the reaction. If you want me to continue, just let me know in descussions and I will.
