Liquifly Water Rocket, deluxe

Prepare for some seriously fun rocket science!

This exciting water-rocket kit contains everything you need to blast a rocket up to 30 meters toward the heavens! That's as high as 9 stories! More than impressive, we say.

The beauty of the LiquiFly Deluxe Kit is that it's all-inclusive - you get the pump and bottle, as well as some useful extras. Designed to demonstrate the principles of thrust, acceleration and jet propulsion: these rockets really fly using only the power of water and air pressure.

The sleek bottle rocket itself features screw on fins to help maintain the correct trajectory, high and low launch valves and a special air-pump specially optimized for Liquifly rocketry.

Try experimenting with different water levels, and varying the air pressure to test how thrust is affected. Full instructions are provided in each kit on safety, set-up and how to really max out your thrust.

Demonstrations at school don't get better than this!

Age: 8+; Warning this is not a toy. It is a seriously fun experiment. Adult supervision required at launch.

LiquiFly Deluxe Kit. Includes a set of fins to keep your bottle rocket on course, a plastic bottle rocket, a high launch and low launch valve, 6 Metres of hose, release fittings and a pump optimised for use with the Liquifly kit.

So get out on a windless day with 2.5 litres of water, and begin counting-down to blast off!

LiquiFly works on the same principle as other water rockets, with the energy coming from water and air. The action of pumping air into the bottle filled with water creates high pressure which forces the water through the restricted opening at high velocity. This creates the thrust needed to launch the bottle high into the air. A fun way to learn about rockets and Newton's third law of motion "every action has an equal and opposite reaction".
