Thanks to Geometry Nodes, the effect is very easy to set up.
Blender FX Artist Max Edge has released a cool new add-on for Blender called Liquid on Curve. With this add-on, you will be able to create fake liquids directly in Blender. The downloadable file contains two collections with the simple setup of just liquid on a curve and the liquid "interacting" with a surface. You can also hover over the input fields in the Geometry Nodes for a tooltip. Evidently, the tool is powered by Geometry Nodes and works in Blender 3.1.
Previously, Max had also released a cool eye rig, also made using Geometry Nodes. The rig allows you to change the eye's color, alter the depth and size of the pupil, iris, and cornea, and even grants you the ability to create narrow, cat-like pupils. You can learn more about the eye rig here.
