The two stage Easter egg rocket

I rigged up a two stage model to celebrate Easter this year. I don't know how it will fly, but it is interesting that it has a lot more propellant mass than anything else!

Update: We did not get to launch this two stage baby yesterday on Easter as it snowed and rained of and on all day long. In the mean time, I did a little research into the technical characteristics of the two stage Easter egg. It is essentially comprised of 22 grams of egg, cardboard fin, and recovery wadding (stuffed inside the eggs to stabilize the motors); 18.8 grams of cardboard engine casing; and 21.6 grams of black powder propellant. If the rocket would fly vertically, which it won't, it would go pretty high - each of the C6 "booster" class engines averages 4.76 Newtons of thrust over 1.86 seconds.

Maybe we will have time to fire it off today...
