example the bottle rocket dat already done
so..let we go through according step by step to proceed da making of bottle rocket
Peel all labels off of the bottles.
Measure up from the bottle about a Third and cut the bottle. Try to keep your cut line as straight as possible. It may help to mark a straight line around the bottle first. Be sure to recycle or reuse any scrap pieces.

 | Take the cut bottle from the previous step and insert it directly over the bottom of the other bottle - this becomes the nose cone of the rocket. Try your best to keep everything straight. If you put the nose on crooked, your rocket will fly crooked. Place the nose cone on loosely at first, then gently press down until firm. Turn bottle upside down and let it drop on a hard surface several times. If you press the nose cone on too hard, you'll start to get "crinkles" in the plastic. Crinkles are bad. Once the nose cone is on tight (but not too tight) use the clear shipping tape to tape the seams. Try to keep tape smooth. | |||||||||||||||||||||||||||||||||||||
Experiment with your own fin designs. i choose a more squared off design, but you can use curves if you like.. you will need a minimum of 3. then, you need to split your bottle into 3 cards, which equals 120 degrees. to make sure there is balancing between the cards.
Open your adhesive (or glue of your choice). Squeeze out a small amount (enough to do one fin). Mix the epoxy with a scrap piece of foam core (this will be your "brush" too). PRE-Mark your bottle (with the marker) where you want your fins to line up. Make sure the fins fit your bottle BEFORE putting any glue on them. Trim, or adjust if needed. Apply the Epoxy to your fin, and attach it to the bottle.
This is where the spray paint comes in.
used BLACK and a Bright Green so that the rocket would be easy to spot while up in the air!
Decorate your rocket any way you like! Flames, spots, checkers, glitter, etc...
Use your extra markers to add any fine details or words (I put H20 on mine so everyone would know this is a water rocket). Add some pin stripes, etc...
(note: as you can see from this photo, I also added some additional tape to the fins for extra support. Do this BEFORE painting.)Perhaps, I should have mentioned this before, this rocket has been added the parachute! What goes up, must come down.
WORDS OF CAUTION:
DO NOT launch this rocket near people, a crowd, small animals, streets or cars or houses... in other words... take your rocket out to the middle of nowhere and launch it in a safe place.
so..its already to be launched
