Construct a water-powered rocket capable of soaring up to 100 ft in the air!
Grades 6–12. In this fun experiment, air is essentially the "fuel" used to pressurize water inside a rocket. When released, air pressure forces water from the rocket at high speed, propelling it upward according to Newton's third law. Experiment by varying the air-to-water ratio and number of pumps (air pressure), observing the difference in launch force. Designed for safety and durability, the rocket has a specially designed safety valve to release excess pressure. Includes step-by-step instructions.
