I recently gave myself a challenge: I wanted to see if I could make a rocket completely with scrap materials anyone can find around their house.
The main body tube: I made this from a tube used to hold golf clubs, it's made out of plastic so it is easy to cut, but it is still strong and sturdy enough to be used in a rocket.
The fins: I made them simply by using an x-acto knife to cut them out from some cardboard.
The nose cone:Â This was the hardest thing to make, but I settled on taking a plastic champagne glass and cutting off the bottom. It worked surprisingly well.
The parachute: I made this using a table cloth and some strings.
The motor holder: I used a threaded pvc pipe for this, because I realized I could just screw the motor into this threaded pvc pipe.
The motor: I didn't make this from scratch, that is done in my homemade motor project. I just used a D12-5 rocket engine. It is very powerful and has a 5 second delay from when the motor finishes burning to when the charge which ejects the parachute is ignited.
Wadding paper: This is a special type of paper that protects the parachute. Although it is commercially available, I made it by simply soaking some paper towels in water that was mixed with baking soda. This worked very well!
In addition to making the rocket, I also attached 2 booster pods on the side and a second stage, meaning this rocket flew with 4 motors!
The motor ejection charge lifts up the nose cone, detaching the booster from the rocket
Gap staging is used to ignite the upper stage (hot gases from the motor in this stage travel up to and ignite the second motor)
