Getting actors to fall when they aren't connected to the group?

[KoShamo]

I’m trying to make a bubble pop game demo and I’m having trouble trying to figure out how I would get floating actors or a group of floating actors to fall down if they are not connected to the main group. Also I’m not sure how I would connect the actors as well. How should I get the actors to fall according to the picture example?

Hey there see if this helps. It’s in html5 and javascript but it might help you organize the code to do what you want.
