I woud like to creat bubble in a glas.
I want the bubble to reach the surface an float one secont then
I tryed "die on emission voulume exit " but they don't stopp...
Do anyone know a expression i can write to make them stopp for a second?

you could use the top surface of the water as a collision plane for the particles.
have it have bounce and friction 0, so the will float along the surfce.
when they collide you can query that in a runtime expression and then set the lifespan by hand to one more second..

that should do it

there is a video tutorial @ gnomon
but you'll have to register.
I anyone knows how to render bubbles, as in how to setup the shader, it tried a few different IOR settings but couldnt get it to look right.
