Build water rocket cars, jet-propelled boats, a water gun, and even a lawn sprinkler. Learn about the laws of physics and their applications in real-world engineering. When you pump air into your rocket, you increase the air pressure inside. Then when you release the clamp, watch out — the mixture inside will shoot out, propelling your rocket and causing it to zoom off in the opposite direction!
