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.
