Rocket

thingiverse

This rocket features a CX-0 engine for launch, followed by a finned bottle rocket. However, this combination is yet to be tested; conduct trials by holding the rocket at its center of gravity while spinning it around. If parallel to your body, add weight to the nose, otherwise no adjustments are necessary. Note that the rocket lacks a parachute, so launch in unpopulated areas. Upon impact, it should not break due to lightweight. To create the finned bottle rocket, cut out notecard fins and attach them; stuff aluminum foil into the top, puncture for ignition upon launch.
