Hi all,

I have a small problem I would like to solve :

Suppose 2 same soap bubbles on a table :

a) glued at each other with a plane separation, what is the volume and shape ?

b) if the separation is made away, forming a unique bubble, what is the final volume ? (note : Vfinal>V1+V2)

Bye.

a.) I kind of imagine two over-sized quarter spheres

attached to each other. I would say they each are 29%

spheres, but look rather like right angled walls: the floor

and the plane of attachment and then they both go upward

a little into the air from the top of the meeting point.

Hi John,

thanks for your info. Did you get 29% from a calculation ? I have a video about but I can't up load it, maybe it's seeable at : https://docs.google.com/leaf?id=0B9pGxyM9yy2fNDMxMjgyYWQtNjQ0Ny00NGYzLTllOTUtMzFkNmIwNGY1MTky&hl=en
