Stylized Grease-pencil/toon shader Chem Beaker.
I also spent 6 hours making a geometry node setup to make the liquid look like the bubbles were more like tar or some sticky syrup that would stick to the bubbles as they floated off the top of the liquid, but then I realized that the toon shader just made it too hard to see, so lesson learned. I’ll include a screen shot of that node setup if anyone is interested, though.
Learned a lot from doing it though. Hope you like it. Included the animation this time, too.
