In another thread (link needed) jamesp posted about using match heads stuffed into a CO2 cartridge and lighting them off as unguided rockets. DANGEROUS! Here is a much safer but still.fun version

Impressive Brilliant Rocketry 101 Shoe string budget Match heads pack a punch of energy Scott. Tempts one to use 2 - 3 - 4 - etc match heads.
Layers of easy to form aluminum foil verses paper in fireworks for containment.
Always wanted to fire a CO2 rocket in a 1" pipe up in the sky over a calm lake and count time to return to earth. Some type of formula should give you an accurate altitude attained.
Thanks for sharing.

Has anybody made Match Rockets using Book Matches and a Paperclip as a Launch Pad ?

I'll stick to high-power rocketry. When you reach level II in the Tripoli Rocketry Association you can make your own propellant grains for your re-loadable engines!

But can you safely return them to launch pad and land them? Well.... we still have to go after them. To guide one coming down is still a no-no according to Uncle Sam. Sounds too much like putting a "payload" on a "target".... I have thought it would be neat to include a small "rover" with GPS and a video camera. Deploy the rover after landing, and have it drag the rocket back to the launch pad.

From the list of childhood do ( NOT ) repeat.
Do not put fire line ( Fast ) fuse, through a cup down the center of a 1" x 3 ft. shd. 40 white pipe Do not pack PINE PITCH around fuse to end of pipe. Do not lay pipe on angle iron at 40 degree lance path across river to rock bar. Three inches of pipe burned before pipe was gone in a cloud of black smoke. solid fuel was very dry Pine pitch, The pitch burn faster then the fuse and pipe. Sparklers, fuel not as good as pitch.

I took this picture of a friend firing a medium sized rocket that I built from an Estes Kit. Also made the Launch control system and the stove pipe launcher too. Probably made 100 rockets and launched 1000 times, still have a coupla boxes of rocket parts for custom rockets. Scanned negative

Probably made 100 rockets and launched 1000 times, still have a coupla boxes of rocket parts for custom rockets. Scanned negative Still got boxes of body tubes in storage, plus enough engines on hand to start W.W.III! Got my other nickname of "Evil Ed" as a vendor at launch sites. Parents would show up with their kids and want to buy parts to build a rocket. I'd refuse to sell them parts unless they had some experience building rockets. I didn't want them going home not knowing how everything fit together, getting discouraged, and never giving it a fair try. I always recommend to newbies to buy a couple kits from Hobby Lobby (use the 40% off coupon you can get online!), build 'em, then see me later for parts. I then ask the kids if they want to fly one of my rockets (never had a kid say "no"). I let them choose the one they want to fly, give them the motor, then talk them through the prep (if parents reach over to help, I have been known to swat their hands and say "let them do it!") the kids then fill out their own flight card, take the rocket through inspection by the Range Safety Officer, then set it up on the launcher- the short kids usually need some help.... . The clubs usually let the kids push the LAUNCH button themselves.... then THEY get to chase and retrieve the rocket! When they bring it back I give them their first rocket kit for free! The other dealers started calling me "Evil Ed" because I was like the corner drug dealer.... "first one's free"......

Two weeks ago I decided to help get a roommate interested in Model Rocketry and dragged out all of my rocketry stuff intending to get back into it. Haven't touched it since that day but I still look at it with interest everyday. I want to make some experimental models that I've been thinking about for a long time now. The last rocket I made was totally custom. It was a 2-Stage powerhouse with a first stage that could be loaded with 1 or 3 or 5 D-engines leading to an upperstage with a single D-engine sustainer. It was 25 years ago and I was planning to fly a 35mm film camera on it. My interests were changing at that time and I only flew that rocket once as a 2 stage with single engine booster without a payload. Have the parts to rebuild this one and will in the near future. Fancy rocket that looked great but didn't fly so well Still have this model but needs some major rework before flying again All scanned negatives

You have got to try the Estes "F" engines! A LOT like the old FSI engines. Estes even makes "F" engines with zero delay for boosters!
I REALLY miss the old FSI F-100 series. Two ounces of cored black powder grain burning in 0.5 seconds!
The f-7 FSI engines were end burning engines. Two ounces of black powder burning over 6 seconds...... We use to call them "steam engines".

When I was flying rockets the D-engines were introduced. There were larger rocket motors available but Estes did not recommend them, and they were mostly made and sold by hobbyists and not always predictable. I worked at a fireworks factory operating a Press that could make 100 tube devices at the same time. I took advantage and made myself 100 rocket engines on a couple of occasions. Even mixed the compositions myself. Made the time delays with Sparkle powder so it would be a little more exciting during the coast phase at the top. Yeah, I called my rocket with 5 D-engines a "powerhouse" but I know there is some really big stuff out there.
