Here is how to make High Pressure Paper Rockets for your hand-held rocket launcher. They withstand over 135 PSI, shoot over 300 feet, are reusable, and only cost around 5¢ each!!
Some quick links to a few of the materials I used:
[✓] Electrical Tape: amzn.to/2cY2wDe
[✓] Hot Glue: amzn.to/2cxdI84
[✓] 1” Sprinkler valve: amzn.to/2cuh4ce
[✓] Momentary switch: amzn.to/2clzVX2
[✓] Tubeless tire valve stem: amzn.to/2cq4goO
[✓] Camo spray paint: amzn.to/2cq3YhH
[✓] Vinyl tubing: amzn.to/2cukpI1
Because of multiple requests for rocket launcher build plans, I spent 3 days putting together a detailed 12 page packet with instructions, part lists, SKU#'s, pictures, schematics, expanded view diagrams, and assembly instructions. I'm selling for $20. You can buy them here if you're interested: bit.ly/RocketRifleParts

Project Inspired By:
The need to make a more durable paper rocket that could withstand 135PSI. The paper and foam versions that I was introduced to would blow up on any pressure over 40 PSI. This was an original design.
Project History & More Info:
These little rockets are about as simple as they get, and yet they are impressively durable. 1 sheet of computer paper is used to form a spacer and the rocket body, then electrical tape is wrapped up the body to reinforce the tube. Electrical tape works great because it can withstand the 135 PSI pressure from the rocket launcher made in a different project.
The fins are made from cardboard, and are about 1/3 as tall as the rocket, and as wide as the width of the body. I use 4 fins because I found that 3 sometimes left the rocket unstable when airborne. 4 fins keep the rocket very straight, and if shot straight up, it can achieve heights that put it out of sight. Trying to catch it on the way back down can result in a red welt on your hand. I speak from experience.
The rockets hold together great and can be shot multiple times. I've noticed that in time, the glue holding the fins starts to give way and a fin may fall off. The extra wraps of tape over the tips and base of the fins help improve the life of the rocket. If you do lose a fin, They can be hot-glued back on, if you don't feel like making a whole new rocket.
Not bad for about 5¢ worth of materials!
