Thames & Kosmos Water Power Rocket-Propelled Cars, Boats, and More STEM Kit


Harness the power of air and water to make things move! Make a big splash into physics with these fun, wet, and wild models.

  • Build water rocket cars, jet propelled boats, a water gun, and even a lawn sprinkler with this science kit for kids. When you pump air into your rocket, you increase the air pressure inside. Then when you release the clamp, the air and water mixture inside will shoot out, causing your rocket to zoom off in the opposite direction!

    Learn about the laws of physics and their applications in real world engineering. Many machines, from the oldest pipe organs to modern day rocket ships use the same technologies that power these water rockets. Experiment to test some of the differences between water and air, and learn why your rocket needs both to go fast.

    • Ages 8+.
    • Build six different air and water powered models.

  • Thames & Kosmos was founded in 2001 by a science museum director and her son, who saw the great need and demand for better science education materials — resources for parents and their children that are more engaging, more effective, more relevant, and more fun.
