A water rocket is a type of model rocket using water as its reaction mass. The water is forced out by a pressurized gas, typically compressed air. Like all rocket engines, it operates on the principle of Newton’s third law of motion. Water rocket hobbyists typically use one or more plastic soft drink bottle as the rocket’s pressure vessel. A variety of designs are possible including multi-stage rockets.
Mousetrap car? What is it? Some people might have wondered what exactly the Mousetrap Car is. It is a physics project in which students design and construct a vehicle with single mousetrap as its sole source of propulsion. A mouse-trap car is powered by the energy of a wound up mouse-trap’s spring. Energy stored in the spring would cause the vehicle to travel in distance if it was under good construction.
Not Water Rocket, Not Mousetrap Car, It’s the Water Rocket Car!!!
A bottle filled with water, strapped on a car, pumped with air; then released will propel the car forward according to a law revealed by Newton in his third law of motion (Action-Reaction). Whether it goes fast or slow, straight or curved, it all depends on slight technical differences that determines the winner.
