Water Rocket Launcher is the famous precision water rocket used in education throughout the world to demonstrate Laws of Motion. It makes great fun in learning science. It is a valuable and visual tool for all levels of science and education. The kit includes: base, trigger, 2 fasteners, 2 galvanized spikes, spare rubber rings. You will Need / Not Included: Drinks Bottle, Pump, Water. Construction details: Almost fully assembled! All you need to do is screw launch pipe into base! The kit includes 2 fasteners for installation on the lawn (ground) or by means of screws, for example on a wooden surface. This mounting method provides absolute stability and allows for tilting the launcher, convenient to install rocket (bottle) without losing water. The valve allows for the connection of the pump, if necessary, to relieve pressure in the system. The launcher tube is made of high-strength PVC pipe reinforced with fiberglass. Metal thread coated makes the connection secure and impervious to corrosion. Each device is being tested. Launch Instructions: Choose a safe area such as a huge field or park away from people, trees, and residences to launch plastic bottles (rockets). Assemble the launcher. Secure the launcher with the two included tent pegs so that it does not move when you pull on the string. Use only water and/or air for fuel. Fill the bottle 1/3 full of water. Tilt your launcher and set the bottle or a water rocket. Attach the air source to the valve on the launcher. Be sure all persons are at least 10 feet away from the launcher, then begin pumping. Launcher supports air pressures between 20 PSI up to 120 PSI. Stop pumping once you achieve the PSI that you desire. Finally, pull the string from a safe distance and out of the splash zone to release the trigger and launch the bottle. Enjoy!
