With this rocket from Liquify, kids can achieve impressive heights of up to 30 meters, or 9 stories, using just water as its power source. The kit comes with all the necessary components, such as fins, a 27cm rocket bottle, 2 valves, a hose, and a pump, to ensure a successful launch. Children can experiment with their water-to-air ratios to see how high they can propel their rocket. This is a fun way to teach kids the basics of STEM concepts, including science and physics, while also encouraging them to spend time outdoors. Designed for ages 9+.
