This is a rocket... based on a flower. We did a hike up to Hope Pass near Twin Lakes Colorado and we saw a flower I had only seen a couple other time before. It's a Red Columbine. It's got kind of a Sputnik look to it.
It is a rear eject spool design that utilizes laminated paper fins formed around a wooden buck.
The nose cone I turned on my wood lathe from a piece of pinyon pine from our own property.
It is powered by a 24mm motor and has an 18" nylon parachute.
Stability calculated using Open Rocket software and verified via a swing test.

Ignition was quick, almost no hesitation lighting the motor.
This rocket is pretty heavy (10.5 ounces) and there was some time lapse between ignition and lift off.
The rocket accelerated quickly, plenty of speed at launch rod exit (33.4 mph per sim)
Winds were less than 5 mph and from the northeast. Surprisingly the rocket weathercocked into the wind, but only a minimal amount.
The simulation software estimated apogee @ 328 feet, and the launch seemed to reflect that (no altimeter was used).
Visually as the rocket descended, the chute was fully deployed.
The rocket ground hit just south of the launch horse.
Photo's were taken of the rocket at it's ground hit location. Upon further review the rocket was undamaged.
