StratoLauncher IV Water Rocket Launcher Kit
Hope you've been drinking a lot of sodie lately because the StratoLauncher IV is jonesing to rocket the bottles it came in over 350' into the air.
The StratoLauncher IV kit from Relationshipware (Relationshipware? Sounds like a company that makes monogrammed towels not water rocket launchers) consists of a metal launcher with 125 PSI safety valve, a pair of StratoFins, and a collapsible fill funnel. It can fire most 0.5, 1, 1.25, and 2L soda bottles, functioning at air pressures as low as 10 PSI for the kiddies, and up to 120 PSI for adults who work best under high pressure conditions.
