here's my next Rig...The Juice Box Rig which stretches,squashes and twists....the juice can perform all these things by adding a non linear deformers like bend twist and squash these deformers help  in creating as sorts of deformations in the poly model..then a deformer known as sculpt deformer is added to show the juice is moving through the straw then a master ctrl is add for the over all scaling rotating and moving of everything ........the juice box rig was fun but quite complicated as many deformer have to be added and two objects had to be rigged...it was quite challenging but introduced me to a whole lot of new stuff.
