Soda Bottle Water Rocket Launcher Fabricated Parts Kit by Relationshipware

One soda bottle water rocket launcher prefabricated parts kit with adjustable trigger mechanism, launch pad, and instructions for assembly and launching. Launcher ships completely unassembled with easy to follow instructions. Launcher will enable you to propel a 2 liter plastic (PET) soda pop bottle over 250 ft. into the sky using only water and compressed air from a bicycle pump, a foot pump for a car, or an air compressor for tools and painting. Fuel (water and air) is essentially free and readily available allowing countless launches without additional expense. Launcher supports air pressures as low as 20 PSI up to 130 PSI. You will be amazed how high only 40 PSI will propel a bottle with fins attached to it. After pumping up the bottle to the PSI of your choice, you control when the launch occurs by pulling on the brightly colored string to release the trigger from a safe distance and out of the splash zone. Launcher supports most .5L, 1L, 1.25L and 2 liter plastic (PET) bottles. Great item for people of all ages for fun, science projects, school classes, parties, etc. and may well draw a crowd where it is used. Trigger mechanism slides up or down by loosening the hose clamp to accommodate variations in bottle construction. Made in the USA from durable non-corrosive Schedule 40 PVC pipe. NO additional expensive materials are required such a wooden board for base, metal mounting brackets, or expensive pulley for string to operate the trigger. Materials and Tools Needed for Assembly: PVC cement, duct tape, scissors, ruler or yardstick, tape measure (optional), flat blade screwdriver (or 5/16 in. or 8 mm socket wrench). Materials and Tools Needed for Launch: Plastic (PET) soda pop bottle, water, air source (bicycle pump, foot pump, or air compressor), 2 tent pegs (wooden stakes, wire hanger, rock, or brick) to keep launcher from moving when the string is pulled.
