Easy to assemble metal water rocket launcher with a 125 PSI safety valve. Rocket will NOT fly straight without an aerodynamic nose cone made from a second soda bottle and use only 1 cup (200 ml) of water.
Kit includes our Gen 4 StratoLauncher + StratoFins (screw-on water rocket fins) + fill funnel. Watch assembly video on this listing at the end of the pictures.
StratoLauncher IV will propel a 2 liter plastic (PET) soda pop bottle over 350 ft. in the sky. Watch the last minute of the assembly video for launch procedure.
Supports most .5L, 1L, 1.25L, 1.5L, 2L soda bottles @ air pressures as low as 15 PSI up to 120 PSI.
Kit is fully upgradeable, expandable, & can be accessorized into a complete launching system for STEM.

Product Information
Product description
Available in 3 Models
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.
Standard - plastic quick connector, no pressure gauge, does not tilt
Deluxe - metal quick connector, air pressure gauge, tilting ball head
Ultimate - same as Deluxe plus Q-connect water fill system made of 4 parts to connect a tank sprayer
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.
View the 3 videos for this listing that cover benefits, assembly, and launch procedure.
Nozzle Efficiency
Requires only 200 ml or less of water to launch a 2-liter soda bottle from the StratoLauncher IV. This means carrying less water onto the field. Also, it functions very well with Air Only. More water can be used, but that will require a rail system or a narrow diameter rocket like an FTC (fluorescent tube cover) rocket.
Nozzle Versatility
Supports 5 different soda bottle sizes (0.5L, 1L 1.25L, 1.5L and 2L) @ air pressures as low as 15 PSI up to 120 PSI. Plus, launch homemade rockets, spliced versions, FTC rockets, gliders, and rocket cars. Although our StratoFins yield the best results, the StratoLauncher IV was designed to enable students and family members to create their own fin and rocket designs that will work merely by screwing on the black nozzle.
Expandable
Connect several StratoLauncher IV units together for large classes or STEM events. Fuel with a single water source (tank sprayer or garden hose) and pressurize with a single air source (bicycle pump, air compressor, or scuba tank) to get through a large field of participants in a short and safe period of time.
Upgradeable
Several upgrades are available to enhance your StratoLauncher IV water rocket launcher.
