I want to make a simple working model to justify newton's third law of motion.
pleez pleen give me an idea
The best (and the only good) project concerning Newton's third law of motion is rockets; either vertical or horizontal launch.
All you would need is a some cardboard which will make the exterior of the chassis. Some explosive material like gunpowder (barood) and an exhaust chamber, preferably made out of something that doe not burn easily, like a hard plastic.
