I've been drafted at the last minute to do a rocketry unit at my wife's school for TAG Week and I'd like to use my unbuilt Decaffeinator as the demo launch. Does anyone know what altitude an Estes BP D12 pushes the Decaffeinator to? Thanks!
 
How heavy is it?

You could use the rough dimensions (diameter, length, weight) and get a rough estimate from thrustcurve.org
 
Using Thrust Curve, assuming a Cd of .85 and a 5 ft launch rod, gives you an altitude of approx 245 ft. If that's a reasonable maximum then I should be ok. I'd be a little more comfortable with info from experienced Caf-heads since I do have a couple other largish low and slow rockets that I could use.
 
Without having the model in hand, that sounds like a reasonable figure.
It's relatively large diameter and very draggy for a D12, but also on the lighter side of life.

Either way, the kids won't lose sight of it! :D

And you could always play Estes E-roulette with an E9 or E12
 
Those estimates are about right, for altitude. A great kid magnet! :)
