Bubbles

I think I have a strange obsession with photographing bubbles.

I think I've done a few blips featuring these magical spherical items of happiness but never one so abstract as this. Although and abstract thought entered my head:

According to Oxford Dictionary, a bubble is designed as 'a thin sphere of liquid enclosing air or another gas'. However, when bubbles bunch together, they cease to be spherical. What do we call them then?

I may need to think of more creative ways of shooting them so I can continue to further investigate and satisfy my craving.
