    It is easier to understand if u flip a bottle of water. The fluid will move inside and cause a bit of friction ( enough to stop it spinning after 1 or 2 turns). If u freeze the water in the bottle (plastic bottle might be better) and flip ( spin it) it will turn for a very long time. Same for the egg.

    It depends on how you spin it up.

    Energy is lost due to the viscose motion of the liquid in the raw egg, slowing it down faster.
