What would be the force diagram of an egg drop land without breaking? If I used a cotton bag to protect the egg?

To stop the egg without breaking, you need to decelerate very slowly.This you can make it many ways. But you must try it several times. Fill the bucket with cotton bag up to half. On the top of it, put grass upto 1/4. Then fill remaining 1/4 by dry leaves. Now drop the egg from a height and check whether it breaks are not.
