    Looks deadly! No, just kiding about the deadly, but it really does look cool. Sadly I have never really gotten into water rockets. Never got how they worked.

    basicly, you fill it up with air, this one is about 70 PSI. when you pull the trigger,the air comes out from a very small space. to keep it simple, all that air(70 PSI is quite a bit of air for such a small space) wants OUT! and it pushes the bottle upwards. LOL i'm a big nerd, so if this doesnt help very much, i encoage you to watch the video.
    hope this helps!


    oh, i get it. it uses air, not water. why then does it say, air water rocket launcher? is it for water bottle rockets?


    well, this one uses 2 liter soda bottle. I guess i should rename it, "The Soda Bottle Rocket Launcher!!!!!!". I guess i named it that because you fill the bottle with 1/3 water.......
