Now I don't know if this is My jedi force power manifesting or if they started making milk jugs bouncy, but I'd like your thoughts.
Btw it was half full, fell from about three feet up, and bounced about two and a half back up, and nothing was spilled.

A couple things were at work here:
Quantity of milk still in container
Height milk was dropped from
Material of milk jug
Material of floor
(Some others too, but you get the picture)
The force of the falling milk jug was counteracted by the normal force exerted back by the floor. This force, plus the pressure of the crumpled half-full milk jug (at the moment of impact) created enough force to "push" the jug back up into the air at the specified height.
If you were to drop a marble or any hard object onto concrete, the object will "bounce" because the normal force from the ground exceeds that of the marble's traveling force exerted on the ground. Newton's Third Law is what's really going on here.
But seriously... Jedi, If that were me, the carton would have exploded and I'd be out some pretty sweet cereal action...
