Take science outdoors with the Water Powered Rocket, an exciting hands-on way to explore forces, motion, and pressure. Using just water, air, and a plastic bottle, this activity vividly demonstrates Newton’s Third Law of Motion — every action has an equal and opposite reaction — as the rocket soars skyward over 30 metres! Learners will love experimenting with water levels and air pressure to test how high their rocket can go, while gaining a deeper understanding of physics principles like thrust, velocity, and propulsion. Perfect for school science projects, STEM days, or weekend backyard fun. Why Educators Love It: Brings core physics concepts to life in a memorable, interactive way Encourages inquiry, prediction, and experimentation Ideal for STEM lessons, outdoor science activities, and group demonstrations Simple setup using common household items Inspires curiosity and excitement about science and engineering How to Use It: Fill a 1.25L plastic bottle partially with water Connect the launch base and pump air into the bottle with a bicycle pump Watch as water shoots through the narrow opening, propelling the rocket high into the air Experiment with different water volumes or pressures to compare results Always launch in an open, wind-free area under adult supervision Details: Demonstrates Newton’s Third Law of Motion in action Reaches heights of up to 30 metres Requires: 1.25L plastic soft-drink bottle and bicycle pump (not included) Fun, educational, and reusable outdoor STEM activity Suitable for ages 10+ with adult supervision Great for science fairs, physics units, and classroom demonstrations
