Experiment Mh-03

Water Rocket

Description: This commercial toy shows that both the exit velocity and the discharged mass are important for moving a rocket. The rocket is filled one third full of water (to the maximum fill line). The remaining air is compressed by 10 to 20 strokes of the pump. Outside, this rocket will rise to a height of 150 feet. This demonstration may be repeated with less water and the same air pressure to show that both the discharged mass and the exit velocity are important in determining the rocket's final motion.


The water rocket attached to the pump in its wooden holder.




Materials: water rocket, pump, water
