Product Review

This is the COMPLETE do it yourself version. All parts included. The launch rail is prefabricated as is the valve stem, but you will need PVC glue to assemble. Once you glue together, screw launch rail tightly and use two included zip ties to secure pull strings (see pictures). Also refer to pictures to see simple assembly (10 - 15 min). This one is different! It has a 'spring' to keep the collar holding the rocket in place during pressurization. Prevents unwanted launches! Also dual string firing mechanism pulls collar straight down instead of to one side, resulting in an instantaneous launch. 'H" design also creates more stability during launch. Launching mechanism is adjustable to accommodate different bottles, just loosen the hose clamp and slide as needed.Launcher will enable you to launch a plastic (PET only!) water or soda pop bottle over 250 ft. into the air using only water and compressed air from a bicycle pump, a foot pump, or an air compressor. The bottles can go way higher with modifications, fins, weight, etc... The fuel (water and air) is essentially free and readily available allowing countless launches without additional expense. Launcher supports air pressure up to 125 PSI.After pumping up the bottle to the PSI of your choice, you control when the launch occurs by pulling on the strings to release the trigger from a safe distance and out of the splash zone. Launcher supports 1L, 1.5L and 2 liter plastic (PET) bottles. Great item for people of all ages for fun, science projects, school classes, parties, etc. and may well draw a crowd where it is used. Made in the USA by ME from durable non-corrosive Schedule 40 PVC pipe and other parts I get at local hardware stores.
