If you have some of the holiday fireworks left over, think of a better way to get rid of them that build a Home Made Rocket Launcher.
Building the first stage rocket launcher was incredibly simple:
1) 2″ pipe over 5" in length to avoid getting blowback in you face
2) Rocket engines, ignitors, launch controller or any device that puts out about 6v
3) Balsa wood and superglue
Cut balsa wood to a fin-like shape, glue onto rocket motor, put in ignitor, profit. This may sound oversimplified but it really isn’t, this will able to achieve a flight of over 2 city blocks with the launcher horizontal with this exact setup. The deviation on the horizontal axis for this flight was about 3". The engines are about $3 a piece and each rocket ends up costing us about $4 a piece, so you don’t want to throw them away, but it isn't outrageous. You can of course, use a standard model rocket, however don’t be prepared to get it back in any usable condition, and be sure to take out the parachute. Trying out new varieties of fins and motor configuration to achieve a steady flight path with regularity, it may take us awhile to get it right, but i assure you, stable flight or not, it’s damn fun.
