Liqufly - Deluxe
This seriously fun experiment uses air and water to power a slick black bottle rocket more than 30 metres into the atmosphere. Within two minutes, the Liquifly rocket is ready to launch - all you need is a windless day, an adult, 1-3 litres of water and a fun-loving and inquisitive attitude.
Liquifly works on the same principles as other rockets, with the energy from pressurised water and air. The action of pumping air into the bottle causes the water to become pressurised and once released, the water escaping through the nozzle creates the trust needed to launch the bottle sky-high!
WARNING: This is not a toy. This is a seriously fun experiment. Adult supervision required to launch.
