Many mechanisms, from the oldest to the most modern, use the same technology that will power your rocket. Experiment with some of the differences between water and air and discover why your rocket needs both to go fast. With this kit, you'll build a water rocket car, a jet boat, and even a lawn sprinkler.

You'll learn about the laws of physics and their applications in engineering through experiments; by pumping air into the rocket, you increase the pressure of the air inside. Release the clamp and...carefully! The mixture inside will shoot out, propelling the rocket and sending it flying in the opposite direction. Wow!

With this set:

• Immerse yourself in the science of physics with six fun, wet, and crazy models;
• Learn about action and reaction forces, rocket propulsion, natural rockets, compressed air, and pneumatics.

This is a great green, natural science project where kids will discover and understand the power and benefits of clean energy while developing critical thinking and concentration.
