# How can I simulate water molecules?

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.

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
