Here's another approach to landing the egg safely -- a cardboard box with shock absorbing rubber bands to secure the payload.
In this vehicle, when the box experiences the jerk force of hitting the ground, the egg/CLUE will slow down more gradually by converting the kinetic energy into heat as the rubber bands stretch. This can act as an effective shock absorber!
For this vehicle you'll need:
- Medium sized cardboard box
- Rubber bands
- Bamboo skewer, or similar
- Scissors or snips to cut the skewer
Build the Suspension Rig
Use the skewer or an awl, nail, or screwdriver to poke a hole at the center of the box walls -- the sides, front, and back will do.
Thread a rubber band (or series of them looped together) through the holes, front to back. Use a small cutoff section of the skewer to hold them in place as shown.
Repeat for the side-to-side connection.
Now, test the new vehicle by dropping it -- you should get a very effective reduction in g-force.
With safe, sub-9g results, it's time to graduate to a real egg! A couple more carefully applied rubber bands make for a good connection system.
