Relationshipware StratoLauncher IV Water Rocket Launcher + StratoFins

Description

Launch a two-liter bottle up to 350 feet into the air with the StratoLauncher IV! This water rocket launch system turns ordinary soda bottles into the fuselages for your aerospace endeavors using nothing but tap water and pressurized air.
Fill up your bottle with fuel (regular tap water), mount it on the launch platform, and pressurize the system with your own bike pump. Then stand back to a safe distance and squeeze the trigger to pull the ripcord and let her fly!
With a built-in safety relief valve, StratoLauncher makes for an engaging STEAM toy that's reusable, safe, and fun for ages 10 and up!
