I take busted up Generic E2X rockets from the school launches and make two stagers out of them to use for demo flights the next year. I have always intended on painting them up and calling them Challenger III's to pay homage to my first purchased rocket, but I never do. Since we almost always lose the sustainer, I just leave the bodies painted as the kids had them when they were single stage rockets.

I'd post some pics from the last few years, but I don't have signed waivers from school. These days, I'd get fired and sued for every rocket penny I have just for posting a picture of a kid having fun on rocket day.
