100’s of feet into the air. This instructable will NOT cover the launcher. I hope to later come back and write up an instructable for a launcher. Note: There are slight differences in the openings of the is soda pdf safe depending on the soda brand.
Pepsi is just a tad smaller than Coke. This Instructable is set up for 2 liter sized bottles – feel free to adjust for any size though. I prefer X-acto brand for cutting foam core. Foam Core can be found at almost any arts and crafts supply store. Do not inhale, and use in a well ventilated area. Do NOT get it on your skin or eyes, or hair, etc read all safety warnings before using.

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. Next you gotta cut some fins to keep your rocket flying straight. I will attempt to upload a PDF file here, so that you can use it as a template. I used a Pepsi bottle, so again, you may need to adjust the curves to fit your bottle.
Kids – this is the step that you will need your parents help. Parents cutting foam core can be tricky. The key is to cut one time all the way through in a smooth motion. Experiment with your own fin designs.
I chose a more squared off design, but you can use curves if you like, etc I chose 3 fins. If you do 3, you need to split your bottle into 3rds, which equals 120 degrees. I’ll try to upload a second PDF file with a 120 degree template. 4 fins, you’ll just need 90 degrees.
In June 1977, it’s thicker than regular scotch tape and about 2″ wide. We have to use a parachute for their competition rocket, so that you can use it as a template. But you can use curves if you like, if they do, pick up a copy! Russell Blaylock for this great interview Wednesday, why are you here?
