Hi...


Here is the reference of what I want.

Simple particles won't give the feel. I have seen one shot in h9 sneak peek, where 
bubbles are generated inside liquid, and they travel upwards.
here is the link....

I
did a simulation of object dropped in a liquid, Liquid reacts properly
but the bubbles are not created. I thought, i would add them, inside
the liquid in the same simulation.
I tried adding another fluid  inside a sphere which is below the water level (as a bubble), and pumping it up, but it doesn't interact properly with the water.

Yes! that's it - my apologies, I forgot it was in the downloadable shelf. 

Thanks for the correction Steve.

don't know that it behaves exactly as you need, but if I recall it just
sends tiny bubbles upwards in a stream from under water. Perhaps if you start
from there then dive into the network, you can get a basis for how to create
your own version?  Just an idea....
