Liquid in a bottle?

Hello,

I've got a quick question regarding something I've been trying to work out for quite some time. I would like to have fluid in a bottle and turn it into a particle effect when it is coming out (so there are no fluid simulations). I would like to have it very similar to the way Job Simulator handles its liquids (here is some examples:

and

around 3:43). If anyone has some source code or could lead me in the right direction, that would be great

Thanks and hope to hear from you guys soon,
Mike S.
