Soap bubbles will assume the shape of least surface area possible containing a given volume. No matter what shape a bubble has initially, it will try to become a sphere. The sphere is the shape that minimizes the surface area of the structure, which makes it the shape that requires minimum energy to achieve.
Experiment
Bend pipe cleaners into several different shapes. Make as many different shapes as you can. You might want to make some square, some circles, some squares, some triangles, some heart-shaped or some even the shapes of letters. Make sure each one has a handle.
Carefully pour the bubble solution in a pie pan. Take each shaped pipe cleaner and dip it into the solution. Now start your bubble blowing.
What shapes are the Bubbles?
