@khairelfarish I just use corrugated cardboard from a shipping box I'm about to throw away. My buddy in Australia, though, he uses corrugated plastic cut from cheap school binders. It's more rigid. In any event you do not need fins nearly as big as what you see on mine. I like big fins because they are cool looking, but for height you want to have as small of fins as you can get away with and still achieve stable flight.
@khairelfarish No. I used an eye bolt for ballast, screwed through the front cap, which kind of makes the thing dangerous like a lawn jart, but if you only thread it through just enough to get a nut on and then you put something over it (like I did with the pointy cap, then it's not going to kill anyone I don't think.
@khairelfarish Materials included two 2L pop bottles, 2-part epoxy resin, cardboard, and an eye bolt. That was for the rocket itself. The launcher was made from 1/2" thickwall PVC, various PVC joints, 1/8" flexible tubing, 1/8" brass coupler, O clamp, rubber O ring (can't remember the size off the top of my head), cable ties, fluorescent tube cover, more epoxy, and pvc primer and cement.
@khairelfarish You can get complete plans for these rockets and a launcher by reviewing an old issue of Make Magazine, issue #5, which I think is available online though you might need to pay a fee. Make issue #5 is what I used to make these rockets.
i wonder if u can tell me what system u use on the launcher to keep the bottle airtight ? .. i'm making a launcher and i don't know what system would be best
its got too much too it to go high mine hit 409 feet we hit a rc airplane altimeter on it. all you need is a 2 liter and a 20 ounce bottle and a foot or so long metal rod to stop it from smashing in to the ground too hard. hot glue the 20oz to the closed end of the 2 liter put a small hole in the cap of the 20 oz put the metal rod in there make about 2 inch fins and you should hit 409 ish for wind and humidity variables.
hey... id like to build a water rocket like this for my high school science project and would like to know how u built it... could u please tell me how
I guess it's a little hard to see. I have been using air compressors (12V) but have used bike pumps. I prefer the hand pumps to the foot ones when I do it that way.
THX for the information ^^ i'll try

It's a "Clark Cable" launcher, developed by a guy named Ian Clark. You can Google the name of the launcher and find directions.
