Relationshipware StratoFins Screw-on Water Rocket Fins + Rubber Stopper Launcher

Product Description

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. This version ships with a rubber stopper launcher for a complete economical package. These fins are compatible with 95% of all available launchers either homemade or commercially available in the marketplace if you want to upgrade the launcher at a later time. StratoFins requires no tools or glue for assembly. The StratoFins kit includes 1 attachment ring, 3 fins, 1 rubber stopper launcher along with an instruction sheet that provides information for creating a nose cone and several launching tips. Assemble StratoFins by sliding each fin down a separate slot on the attachment ring beginning from the top. With all fins in place screw the attachment ring onto a soda bottle until snug. 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. Great item for people of all ages for fun, science projects, school classes, parties, etc.
