StratoLauncher + StratoFins Water Rocket Launcher Kit by Relationshipware

The StratoLauncher kit includes a preassembled water rocket launcher, an adjustment tool, StratoFins®, 2 tent pegs, and easy operating instructions. Tilt launch tube to a 90 degree angle and rotate to the center of the launchpad, thread the string through the eye screw and it is ready to use. Launcher will enable you to propel a 2 liter plastic (PET*) soda pop bottle over 350 ft. into the sky using only water and compressed air from a bicycle pump, a foot pump for a car, or an air compressor. Fuel (water and air) is essentially free and readily available allowing countless launches without additional expense. StratoLauncher supports most .5L, 1L, 1.25L and 2 liter plastic (PET*) bottles at air pressures as low as 20 PSI on up to 120 PSI. You will be amazed how high only 40 PSI will propel a bottle with StratoFins® attached to it. After pumping up the bottle to the PSI of your choice, you control when liftoff occurs by pulling on the brightly colored string to release the trigger from a safe distance and out of the splash zone. Great item for people of all ages for fun, science projects, school classes, parties and may well draw a crowd where it is used. Made in the USA from durable non-corrosive Schedule 40 PVC pipe and HDPE plastic. NO additional materials are required such as duct tape, wooden board for base, metal mounting brackets, or expensive pulley for string to operate the trigger. This is a complete launcher, NO gluing, taping, cutting, or measuring required. You will need to supply: Plastic (PET*) soda pop bottle, water, and air source (bicycle pump, foot pump, or air compressor). No tools required for assembly or adjustment. * Polyethylene terephthalate (aka PET) is a thermoplastic polymer resin of the polyester family that is used in soda pop bottles. Serious bodily injury could result from using any other type of bottle.
