Description

Extra bottles let you make extra rockets!

Get a plain one for your regular water rockets.  This is a standard plastic 2-liter pop bottle of the type used to hold fizzy pop (not a water bottle!)

Get a booster stage for your multistage rockets.  This 2-liter bottle has been specially modified and has all the attachments to work with AntiGravity 2-stage water rockets, including the interstage release mechanism.

Or get the SuperBottle for your very-high-altitude water rockets.  With its narrow rocket-like shape, the reduced cross-sectional area and correspondingly minimized air friction, it will definitely make your rockets stand out in any crowd.
