This one was hard. The node setup is simple, but it was really difficult to get something good from it. I'm not happy with the result, but decided to upload anyway. Would be fun if someone can improve on this and do something better.
The two main problems.
1. Y-resolution is terrible.This is due to the speed of the liquid.This animation is simulated with a time scale of 0.5. But it's still really bad.
2. Chaos. The liquid tends to do weird things that spoil the effect.Of course, without this it wouldn't really look like liquid.
