Here's how to take everyday sprinkler parts and convert them into a portable, hand-held rocket launcher! It's cheap to make, easy to use, and will send a paper rocket over 300 feet!!
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 to help compensate for my time. You can buy them here
