Our StratoLauncher® IV, water rocket launcher is available in 3 models: Standard, Deluxe, and Ultimate. All of them perform the same and can be upgraded to add additional features and all come with a 125 PSI safety valve to prevent exploding bottles while pressurizing.

Our complete launcher kits will enable you to propel a 2 liter plastic (PET*) soda pop bottle over 350 ft. into the sky using only water and compressed air from a bicycle pump or an air compressor. Fuel (water and air) is essentially free and readily available allowing countless launches without additional expense. StratoLauncher® supports most .5L, 1L, 1.25L and 2 liter plastic (PET*) bottles at air pressures as low as 15 PSI up to 120 PSI. After pumping up the bottle to the PSI of your choice, you control when liftoff occurs by squeezing the lever to release the rocket from a safe distance and out of the splash zone.
