One DIY soda bottle water rocket launcher prefabricated parts kit with adjustable trigger mechanism, durable ABS plastic launch pad, 2 tent pegs, a set of StratoFins®, 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 bottle over 350 ft. into the sky using only water and compressed air from a bicycle pump, a foot pump, or an air compressor for tools and painting. Fuel (water and air) is essentially free and readily available allowing countless launches without additional expense. 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. 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). StratoFins® will guide your rocket to lofty heights with straight flights instead of tumbling through the air. StratoFins® are made of durable plastic and screw-on to a 2 liter soda bottle or smaller. The StratoFins® kit includes 1 attachment ring and 3 fins along with an instruction sheet that provides information for creating a nose cone and several launching tips. This water rocket can be launched with or without a parachute attached since this configuration does not nose dive, but instead tumbles gently back to the ground provided the nose cone is NOT permanently attached.
