Hello,
i want to make a simulation like this:
http://www.shutterstock.com/video/clip-8366917-stock-footage-effervescent-pill-dissolves-in-glass-of-water-tablet-dissolving-in-glass-water-blue-background.html
I don’t know how to make air bubbles in fluid, which look like those in that stock.
Any ideas? 
The most obvious way is to make a fluid using a particle system where each particle is a metaball, and then making air particles that are negative metaballs.
But that would require a very high metaball resolution for fine bubbles.
Hey.
Make a tablet than emit objects (spheres) with particles.
Is that it?
Take care.
Yes, but bubbles need to float on surface of a water 
Yes, make the surface of the liquid a collision surface e.g.
Did not come out so well because for transparency and refraction need a lot more samples
Maybe easier to see wireframe?
So this is with a particle system using meta-balls and a collision surface at the water boundary
Hope this helps
Martin
I think this could work, Thanks!
Hi! Metaballs works, but they are quite computational expensive. Instead of metaballs i just used normal icospheres and placed a plane on the water level to kill them once they reach it.
-here’s the result:
I would do something very similar to thankz, but in my mind you should flip the normals on the icosphere. Otherwise what you have is like glass marbles in the water.
