I have an old gunpowder rocket lying around in the garage, I am debating whether or not to dig it out. It is a fairly simple thing if I remember correctly, only 2 stages and the payload has a parachute for landing.
I would like to know if anybody is interested in seeing a video / slideshow / instrucable on it?
While I'm there I might find my old water rocket valve.
And if I'm feeling really bored, I might make my own rocket and charges :-)
