Juice box

This rig is featured for the following things:
1)stretch & squash
2)twist
3)bend
4)sipping action with size of it (quantity of juice)


 * Stretch & squash
This feature is created using squash handle which is available in create deformer  nonlinear  > squash deformer > nonlinear > squash deformer . (maya)

*Twist
This is created using the twist deformer which is also available in nonlinear  deformer

*Bend
This is created using the bend deformer which is also available in nonlinear  deformer . This and the squash deformer give this juice box a jelly movement

*Sipping action
This action is created sculpt deformer , this deformer is connected to a path curve so that the sip movement can happen all around the straw so repeat this action turn on the infinity under view in graph editor and go to curves under this option turn on post infinity and pre infinity . by doing this your action will be repeated several time(∞)

Here is what I have done with some screen shots:
1)Outliner

 2) Naming with functions of curve

 3)For looping your animation (action) several time

And finally the test rig that I have created watch it for more info
