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.

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.
