Adrian C. Koutz shows how to create a simulation of pouring liquid right in After Effects with the help of the Newton Physics Engine.

In this tutorial, I will explain how to use Newton to simulate liquid that interacts with the container it’s being poured in to

Adrain walks through the process of creating collisions between the liquid and its container, and also provides some alternative techniques for doing the same thing in Trapcode Particular with a 3D environment.
