How can I simulate water molecules?

Question

I'm trying to use Particle system to simulate water molecules, like this https://www.youtube.com/watch?v=iB7tLjqsKMY or https://phet.colorado.edu/sims/html/states-of-matter-basics/latest/states-of-matter-basics_en.html . But i don't know how to shake or wiggle the molecules. I'd like to make something very similar.

maybe my answer here will help: https://blender.stackexchange.com/questions/237249/how-can-i-recreate-this-emitting-rigid-body-force-field-animation/237276#237276 — moonboots, Nov 24 '21 at 20:48

I am using geometry nodes for this (which for sure will be or is already the better particle system) and with this node setup:

you will get this:

Note: of course you can do this better and play around with the values a bit, but i think it is a good starting point

Thanks so much for the reply. Was the model created in Blender 3.0 ? With all this tips, I think I can create a good model. Tks – john Nov 25 '21 at 18:18
The model was just 3 spheres and then I joined the objects – Chris Nov 25 '21 at 18:42
