Water enclosed in body with floating balls game in iPhone

This is my first post in stackoverflow so kindly bear with if i make any mistakes.

I am trying to develop an iphone game with water enclosed in a container with balls . I am not sure how to get about with the effects that would be required and which framework woul开发者_StackOverflow社区d be suitable for this work. Kindly anyone could direct me with some help would be greatly appreciated. Also the tutorials i would require during this process.

You probably need a physics engine to model the ball movement.

See the related question for information about physics engines that will run in the iPhone: Is there any physics engine SDK for iPhone/iPod touch and iPad?
