Designing an Eggernaugt Landing Device?

It sounds like there is a favored design of your professor, but most of the successful egg-drop systems I've seen (I've been a Cub Scout leader for these events about a dozen times, and some Cub Scouts rival any engineering cl) are not the more elaborate. Consideration must be given not only to the impact side, but also to the following side, which carries it's own inertial force. An egg in a firm-foam cast, carefully fitted to close tolerances, was often the safest. I don't understand what all the paraphernalia is that you have to work with. I wouldn't use most of it. I think you'd be best carving out three egg shapes in the pool noodle and attach it safely inside the shoe box. By adding sand you're creating a traveling m that could crush the cargo.
