Rockets!

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 :-)

Water Rocket Launchers

Water rockets are fairly new to water warrior technology. To reduce our carbon footprint, water rockets are built using plastic bottles. This forum topic talks about the operation of standard water rockets and launchers, how they can be used in a water war, construction of water rocket launchers, rockets, and add-ons like water balloons on the tips of rockets, ammo clips, and grips as well.

How To Build A Rocket

A few years ago i came up with the idea of strapping a rocket to a merry-go-round. the little ones in playgrounds not the big ones with horses and stuff. i've been trying to find some sort of rocket hobby community since then but there are surprisingly little. and not a whole lot of instructables on rockets with enough power. so tips? hints on how to at least get started?

How to make (or where to buy) spring loaded fins for a model rocket? Answered

I think it would look really cool if I could launch model rockets from some sort of tube or underground silo. The only problem is that the fins get in the way of securely packing the rocket in the tube. I would like to know if there are plans for spring loaded fins or if there is a place where I could buy a set of spring loaded fins.

Need advice on making a proposed rocket I've devised different to the ones seen on here, before I waste materials?

I was thinking of making a rocket and using the fuses in a party popper as the propulsion, I was going to set up 4 gutted poppers with just the fuses on a 600ml/1 or 2 lt bottle and use a string fuse attached to the popper fuses at equal distrance running into a centre fuse/string to light it and get clear.I would use skewers or something to make it launch straight up.I would have the bottom of the popper housing/film cannister against the ground/launch pad. Has anyone tried this? Would the popper/poppers just simply blow up the thing I put them in and not work? Would I be better of doing the film cannister cannon thing instead of poppers.?

Help with multistage balloon-tipped water missile

I'm designing the perfect water weapon of mass soakage-the super water missile, and I'm shifting my attention to multistage water rocket thrust systems. My finished product will hopefully be able to reach high altitudes, acheive moderate horizontal distance, and either drop many water balloons over a specified target area, or be tipped with a very large water balloon for a "wet impact" (very wet). I don't know how multistage water rockets operate though, and there are no instructables on how to build them. I searched Google, and all I got was pictures. No DIY's, how-to's, or tutorials. Could anyone tell me (or better yet-show me) how to make a multistage water rocket-or at least how they operate?
