rendering bubbles

any ideas on how to realistic bubbles, I would like maybe even water dripping and the colors being weird like in them too.

Sounds like you want semi-transparent spheres in a particle system. As for the ‘weird colors’ bit, you might want to use Nodes to create the material(s). I’m not really sure of the exact procedure, though.

The magic procedural texture set to ‘nor’ coordinates should do the trick.

If you want bubbles in water, model a water volume then create the bubble meshes as part of the same object, but with the normals pointing inward.
